This release adds microphone processing controls and local chat controls, expands platform packages, and synchronizes the website and guides. It also fixes native H.264 input/format handling, signaling recovery, fresh STUN discovery, and UDP ownership during overlapping connections.
This is **v1.8.0**. Browser/Server v23, Native control v9 and capture v7 remain unchanged, with the existing 1440p ceiling. Additional resolutions, capability negotiation and Magicsock are separate follow-up work.
## Validation
- Full local Web check: 79 files / 1,317 tests, TypeScript and production build.
- Full Go checks, platform builds and Windows native capture regressions/probe.
- Native H.264 Host lifecycle, Browser-to-App fanout and App-exit recovery, and Native H.264 through embedded SFU: all passed with owned process/port/profile cleanup.
- Website build, documentation and repository hygiene passed. Existing UI acceptance covers narrow screens, both languages/themes, architecture downloads and all 23 film checks; final packaging and Go race checks run on the merged revision in CI.
- Physical macOS/Linux capture, representative public networks and unmatched field reports retain their documented evidence limits. No claim that every blur/disconnection report is resolved.
## Release notes
### 中文
这是一次功能与兼容性更新：麦克风和聊天增加了实用的小选项，App 与 Server 支持更多设备，同时修复了原生分享和连接恢复中的若干问题。现有 1.x 协议保持不变。
#### 新增与改进
- 浏览器麦克风新增「降噪与回声消除」开关，默认开启回声消除、降噪和自动增益；分享音乐或使用虚拟音频输入时，可按需关闭。
- 可调整弹幕字号和透明度，并将当前保留的聊天记录导出为 TXT。当前会话最多保留 1,000 条文字消息，刷新页面后清空；需要保存时请先导出。
- 新增 Intel Mac、Linux ARM64 App，以及 Linux ARM64 Server 和容器镜像。官网下载区可直接选择对应架构，并显示最新版本和发布时间。
- 更新官网演示、README 截图和中英文教程，明确浏览器分享也可选择窗口或屏幕；开始分享前显示房间号占位，保持底栏控件位置稳定。
- 官网新增直达问题排查的入口，补充浏览器 WebRTC 限制、校园网和 Windows 显卡相关的排查步骤。
- App 模式选择页显示免费开源说明、作者与贡献者署名，以及官方网站和源码链接。
#### 修复
- 修正部分 H.264 原生分享的格式兼容性校验，以及 Windows 编码器输入长度和输出缓冲区对齐问题。
- 清理已失效的重连任务和 Native 接收信令，避免旧连接继续影响当前会话。
- 修复 App 重连时可能复用过期公网地址的问题；重新探测使用当前地址，并处理探测丢包和过期响应，保留其他正常连接。
- 修复 App 新旧媒体连接重叠时共用端口造成的冲突，避免准备或撤销新连接打断仍在使用的画面；关闭连接时及时取消未完成的端口映射请求。
- 无站点密码时，连接恢复不再误引导用户输入站点密码。
- 房间失效或会话终止时，开播前后的原因提示统一显示在电视状态图标中，避免额外提示条。
- 修正 Linux 原生采集的时间戳与关键帧时间基准。感谢 Pedro Antonio 在 [#449](https://github.com/TNTcraftHIM/Piik/pull/449) 的贡献。
#### 使用说明
下载对应平台的完整压缩包，退出旧 App 后解压使用。Windows 继续提供 x64；macOS 提供 Apple 芯片与 Intel 版本，原生采集需要 macOS 13 或更新版本。Linux 提供 x64 与 ARM64，原生采集还需安装[系统组件](https://github.com/TNTcraftHIM/Piik/blob/main/native/capture/linux/README.md)。macOS 和 Linux 的实机覆盖仍有限，欢迎反馈。
### English
This update adds useful microphone and chat controls, brings Piik to more devices, and fixes several native-sharing and connection-recovery issues. The existing 1.x protocols remain unchanged.
#### New and improved
- Browser microphones now have a “Noise & echo reduction” toggle. Echo cancellation, noise suppression and automatic gain control are on by default; turn them off when appropriate for music or virtual audio inputs.
- Adjust chat-overlay text size and opacity, and export retained messages as TXT. The current session keeps up to 1,000 text messages and clears on page refresh; export first if you want to keep them.
- Added Intel Mac and Linux ARM64 App packages, plus Linux ARM64 Server and container images. The website provides architecture selectors and shows the latest release and publication date.
- Updated the website demonstration, README screenshots and bilingual guides, clarifying that browser capture can also select windows or screens. A room-code placeholder keeps the bottom bar stable before sharing starts.
- Added direct website links to troubleshooting, with steps for browser WebRTC restrictions, campus networks and Windows graphics issues.
- The App mode-selection page now shows its free and open-source status, author and contributor credit, and links to the official website and source.
#### Fixes
- Corrected H.264 format compatibility checks and Windows encoder input-length and output-buffer alignment handling.
- Retired stale reconnect tasks and Native receive signals so they cannot continue affecting the current session.
- Fixed App reconnection reusing an expired public address. Fresh discovery handles lost probes and stale responses while preserving other working connections.
- Fixed UDP socket conflicts between overlapping App media connections so preparing or canceling a replacement preserves the active picture. Closing a connection now cancels unfinished gateway mapping requests.
- Connection recovery on passwordless sites no longer incorrectly asks for a site passphrase.
- Expired-room and session-termination reasons now use the same TV status indicator before and during sharing, without an extra notice strip.
- Corrected Linux native capture timestamps and keyframe time bases. Thanks to Pedro Antonio for [#449](https://github.com/TNTcraftHIM/Piik/pull/449).
#### Updating
Download the complete archive for your platform, quit the old App, and extract the new package. Windows remains x64-only. macOS packages support Apple silicon and Intel; native capture requires macOS 13 or newer. Linux supports x64 and ARM64 and requires additional [system components](https://github.com/TNTcraftHIM/Piik/blob/main/native/capture/linux/README.md) for native capture. Physical-device coverage on macOS and Linux remains limited; feedback is welcome.

## Problem and outcome / 问题与结果
This phase adds lightweight room interaction without making media depend on chat,
and adds Windows source-audio exclusion and optional SFU-only hosting at their
existing owners. It also corrects confirmed encoder/capture ownership and native
color-conversion defects. Host microphone commentary remains on the shared media
path; room voice and 4K are outside this phase.
## Release notes
### 中文
这是一次功能更新：Piik 加入了文字聊天与表情互动，并完善了 Windows 声音采集、画面颜色和自部署选项。
#### 新功能
- **边看边聊。** 在可移动、可缩放的聊天窗口中发送消息，或开启弹幕。停止分享后，房间中的朋友仍可继续聊天。
- **表情互动。** 点击沙发上的人物，给自己发表情，或把番茄等表情送给朋友；各端按同一事件显示动画。
- **排除应用声音。** Windows App 分享整个屏幕时，可排除一个应用及其子进程的声音，适合同时使用语音软件。所选应用退出后，来源声音停止，避免恢复为未过滤的系统声音。
- **可选的纯 SFU 模式。** 自部署管理员可让共享画面和声音统一通过媒体服务器转发。默认仍为优先 P2P；App 公网邀请保持纯 P2P。
- **Windows HDR 转 SDR。** 原生采集与缩略图自动将 HDR 来源转换为 SDR，沿用现有观看链路。
#### 修复与改进
- 修复原生颜色转换的范围与矩阵处理，避免已复现的暗部丢失、高光裁切和颜色偏差。
- 修复共享编码器切换时使用过期需求或过期帧信息的问题，保护正在观看的画面；修复换源后旧采集事件可能影响新来源的问题。
- 统一新控件、浮窗与来源选择文案，补充中英文使用说明。
#### 使用与升级
聊天与表情需要新版站点页面和 Server；声音排除需要新版页面与支持此能力的 Windows App。聊天只保留本页最近收到的消息，刷新后清空，不补发历史，且不提供端到端加密。
HDR 转换输出为 SDR，不代表端到端 HDR 或多声道支持。既有房主麦克风与立体声能力保留。
### English
This feature update brings text chat and reactions to Piik, alongside improvements to Windows audio capture, picture colors and self-hosting options.
#### New features
- **Chat while watching.** Send messages in a movable, resizable window, or enable on-screen chat. Friends can keep chatting after the host stops sharing.
- **Reactions.** Select a person on the sofa to react above yourself or send a tomato and other reactions to a friend. Participants animate the same shared event.
- **Exclude application audio.** When sharing a whole screen with Windows App, exclude one application and its child processes, useful when using a separate voice app. Source audio stops if the selected app exits, preventing a return to unfiltered system sound.
- **Optional SFU-only hosting.** Site operators can require shared video and audio to pass through the media server. P2P-first remains the default; App Public invite remains P2P-only.
- **Windows HDR-to-SDR conversion.** Native capture and source thumbnails automatically convert HDR sources to SDR for the existing viewing path.
#### Fixes and improvements
- Correct native color-conversion ranges and matrices, addressing reproduced crushed shadows, clipped highlights and color shifts.
- Correct stale demand and frame evidence during shared-encoder handoffs to protect the current picture. Prevent events from a replaced capture from affecting its successor.
- Align new controls, floating panels and source-picker copy, with updated Chinese and English guides.
#### Using this update
Chat and reactions require updated site pages and Server. Audio exclusion requires updated pages and a Windows App that supports the capability. Chat retains only recent messages received by the current page, clears on refresh and does not replay history. It is not end-to-end encrypted.
HDR conversion produces SDR; it does not add end-to-end HDR or surround sound. Existing host microphone commentary and stereo support remain available.
## Verification / 验证
- Web type checks, 78 test files / 1275 tests and production build: PASS.
- Go core tests, formatting/vet and target builds: PASS; Darwin cgo remains platform-limited on this Windows runner.
- Native build/check/color probes and synthetic HDR-to-SDR H.264/VP8 browser reception: PASS.
- Access/privacy gate, Native H.264 SFU-only media gate and local Auto/H.264 Host gate: PASS.
- Three real production pages: chat/reactions, stop/resume, idle-room join, host departure/return, offline draft recovery and invitation revocation: PASS.
- Synthetic parent/child process-audio exclusion and target lifetime: PASS; no raw audio retained.
- Windows candidate archive extraction and packaged Local startup/shutdown: PASS.
- Documentation and website build: PASS.
- [Candidate CI](https://github.com/TNTcraftHIM/Piik/actions/runs/36873766646) at
`f26cd208d03bc0dcbe353f8cac217f993216b0a3`: Go core and race checks, Web tests,
Server/container checks and Windows/macOS/Linux App packaging all PASS.
Publication was skipped as intended.
The owner accepted the UI/model and bounded local walkthrough for phase closure.
Physical HDR/mixed displays, mobile keyboard,
real voice applications across output devices and macOS/Linux capture remain
unverified. Existing field reports without matched evidence are not claimed
resolved. The owner authorized v1.7.0 publication on 2026-10-02. The final
documentation-only commit records that authorization; product code matches
the verified candidate above.
## Impact / 影响
Authorized version: **v1.7.0**, matching the local release planner. Current wire
contracts remain Browser/server 23, Native control 9 and capture 7. Optional
capabilities gate new functionality; existing room/media authority remains owned
by the existing services. No new ports, message persistence, room voice or
automatic room creation on page visit. Updated README, guides, standards,
research evidence and TODO stay with the candidate phase.
## Problem and outcome / 问题与结果
This maintenance phase fixes failures around native capture startup, room reconnection and media handoffs. Capture mutations stay cancellable, relayed-content failures remain request-scoped, and failed media connections return to the existing route controller. Windows Auto codec selection measures delivered cadence instead of timer-sensitive per-frame work estimates.
The phase preserves P2P-first routing, one committed graph and one route operation. It adds no signaling replay mechanism, changes no wire/schema version, and includes no interaction prototype or 4K feature work.
## Release notes
### 中文
Piik v1.6.8 是一次稳定性修复，重点改善 Windows 原生采集、断线恢复和分享过程中的控制响应。
#### 修复与改善
- **更准确地选择编码器。** Windows 的自动模式按实际出帧表现评估 H.264，并正确区分启动预热和持续性能不足，减少计时误差导致的不必要 VP8 回退。硬件编码事件改为异步等待。
- **改善断线与线路切换。** 房间信令短暂断开后保留观众成员身份 20 秒；修复线路切换、SFU 订阅恢复及声音重协商卡住的问题。失效连接及时交回现有路由控制器处理，原生 SFU 发送端不再把短暂断连直接判为终止。
- **保持 App 控制响应。** 开始分享和更换来源时仍可取消操作；合法消息突发不再直接关闭控制连接。中继信令的单条内容错误不会连带结束整场原生分享。
- **修正设备列表与配置保存。** 来源或麦克风数量达到上限时保留可用列表；配置替换失败时保留原有设置。
- **改善紧凑布局和辅助功能。** 调整手机横屏下的画面与播控布局、画质预设标签和长邀请链接显示，修正部分提示与辅助功能语义。
- **加强站点访问保护。** 站点登录 Cookie 使用独立随机签名密钥，应用自身阻止被其他页面嵌套。发布说明也会在合并前检查。
#### 升级说明
通信协议和持久化格式保持不变。设置了站点密码时，App 或 Server 重启后需要重新输入站点密码；持久化房间和邀请授权不受这项 Cookie 调整影响。Piik 操作页面不再支持嵌入 iframe。
### English
Piik v1.6.8 is a stability update focused on Windows native capture, connection recovery and responsive sharing controls.
#### Fixes and improvements
- **More accurate codec selection.** Windows Auto mode evaluates H.264 using delivered frames and distinguishes startup warmup from sustained performance limits, reducing unnecessary VP8 fallback caused by timing noise. Hardware encoder events now use asynchronous waiting.
- **Improved reconnection and route handoffs.** Viewer membership survives brief signaling outages for 20 seconds. Fixes cover route activation, SFU subscription recovery and stalled audio renegotiation. Failed connections return to the existing route controller, and the native SFU publisher no longer treats a transient disconnect as immediate termination.
- **Responsive App controls.** Starting a share and replacing its source remain cancellable. Valid message bursts no longer close the control connection, and an invalid relayed payload cannot terminate the entire native sharing session.
- **Device lists and saved settings.** Source and microphone enumeration retain a usable list at their limits. Failed configuration replacement preserves the previous settings.
- **Compact layouts and accessibility.** Improved picture and playback-control layout on landscape phones, quality preset labels and long invitation links, with corrected tooltip and accessibility semantics.
- **Stronger site-access protection.** Login cookies use an independent random signing key, and the application prevents embedding by other pages. Release notes are also checked before merge.
#### Upgrade notes
Wire protocols and persistent formats are unchanged. If a site password is configured, restarting the App or Server requires entering it again; this cookie change does not revoke persisted rooms or invitation grants. Piik operation pages can no longer be embedded in an iframe.
## Verification / 验证
- `npm run check`: passed, 76 test files / 1,171 tests, TypeScript and production Web build.
- `npm run check:go-core`: passed; full Go/native checks also passed during integration of the capture changes. macOS cgo builds remain native-runner checks.
- Windows native Host gates: Auto, H.264 and VP8 passed during the phase; final control changes rechecked with Auto, including live/paused quality, source replacement, failure retirement and subsequent sharing.
- Embedded SFU browser VP8 recovery: passed with production Host/Viewer route owners.
- Embedded SFU native H.264, two rooms: passed, including recovered decoded video/audio, independent room retirement and resource cleanup.
- Documentation, repository hygiene and diff checks: passed. Final follow-up changes only align operations documentation with the PR note check.
- Go race checks could not run locally because no cgo/GCC toolchain is available; the existing Linux CI race job remains required. AMD/Intel hardware, broader device combinations, public-NAT field reports and long endurance are not established by these local checks.
## Impact / 影响
Compatible patch release after v1.6.7. The cookie and frame-protection effects are disclosed in the public upgrade notes. No automatic retry budget, room-code admission policy, room lifetime or media topology is replaced. Reports without matched diagnostics and unmeasured native performance costs remain in the TODO ledger.
## Problem and outcome / 问题与结果
Native sharing could start capture before discovering that the browser could not create its local media connection. Connected Viewer routes could also be retired solely because decoded frames stopped advancing, including quiet or backgrounded game sources. This maintenance phase acquires the browser bridge before capture, preserves connected routes through frame silence, scopes Native keyframe recovery to the requested outputs, and reports terminal Browser sender failures to the existing connection owner. It also includes the accepted narrow-screen layout and tooltip corrections.
## Release notes
### 中文
这是一次维护更新，重点修复分享启动、观看连续性和手机窄屏布局。
- 修复浏览器媒体连接无法初始化时，App 仍启动采集后立即停止的问题，并保留更明确的失败原因。
- 避免仅因画面暂时没有更新，就断开已连接的观看线路；适用于游戏切后台等静止画面场景。
- 修正原生画面恢复请求的范围，避免某一路请求关键帧时影响其他输出；浏览器发送失败也会及时通知现有连接处理流程。
- 修复窄屏下房间号与操作按钮的排布，改善长标题和提示浮层的显示。
短时模糊与部分用户报告的偶发断流仍在调查，本次更新不代表所有相关情况均已解决。升级 App 或自部署 Server 后刷新页面即可，无需修改配置。
### English
This maintenance update focuses on sharing startup, viewing continuity, and compact layouts on phones.
- Fix capture starting and immediately stopping when the browser cannot initialize its local media connection, and preserve clearer failure details.
- Keep connected viewing routes alive when the picture temporarily stops updating, including quiet or backgrounded game sources.
- Keep Native keyframe recovery scoped to the requested outputs and report terminal Browser sender failures to the existing connection handler.
- Fix room-code and action layout on narrow screens, and improve long headings and tooltip placement.
Brief quality drops and some reports of intermittent stream loss remain under investigation; this update does not claim to resolve every reported case. Update Piik App or your self-hosted Server and refresh the page. No configuration changes are required.
## Verification / 验证
- `npm run check`: 76 files / 1,133 tests, TypeScript and production Web build passed.
- Targeted Browser sender/pool checks: 97 tests passed on maintenance and interaction candidates.
- Go mediaedge/nativehost/nativecapture/forwarding tests and scoped vet passed; output-scope regression tests reject the old behavior.
- Matched Chrome 152 VP8/H264 ordinary/pool tests with two viewers and a one-second network constraint completed with healthy sibling isolation. VP8's deeper pooled quality dip remains open.
- Physical startup/resource-exhaustion and quiet-game reproduction boundaries are documented in the existing research owners.
- `npm run check:go`: formatting, Go tests/vet, Windows/Linux builds, Windows native capture compilation/probes and regressions passed. Darwin packaging and Go race checks run on the native CI runners.
- Actual Windows App H264 and VP8 Host gates passed: decoded video, live/paused profile changes, quiet/background-source recovery, source replacement, failure cleanup and subsequent sharing; all experiment-owned processes and ports closed.
- Website build and repository hygiene checks passed. Independent full-phase frontend and native reviews found no release-blocking regression.
## Impact / 影响
Patch release v1.6.6. Browser/server v23, Native control v9, capture v7 and SQLite schema 2 remain unchanged. No interaction prototype, route-selection policy, new quality heuristic, or configuration migration is included. Real-phone and heterogeneous network/device coverage remain bounded by the existing verification record.
Public invitations could stop after an early tunnel-process exit, and connection progress and Viewer status did not consistently describe the current attempt or Host state. This maintenance release adds bounded startup retries, aligns enhanced NAT retry feedback across entry paths, and fixes camera-preview and room-entry layout.
The existing route owner and published contracts remain in place. Four-attempt progress is advertised and opted into; older readers retain supported messages. Interaction/chat experiments are outside this PR.
Validation: npm run check (74 files, 1072 tests and production build), npm run check:go (including Windows capture compile), documentation/repository hygiene, 10 production Viewer-entry discovery cases, and a real public-link gate with remote HTTP/WebSocket access and shutdown cleanup all passed. Existing device/network evidence limits remain documented.
## Release notes
### 中文
这是一次维护更新，重点改善公网邀请启动、连接重试反馈和分享状态提示，并修正两处界面布局问题。
- 公网邀请服务在连接就绪前意外退出时，会自动重试，最多重试 3 次；所有尝试仍共用 30 秒启动预算。
- 增强穿透连接在首次尝试失败后最多重试 3 次，重试进度显示为 1/3、2/3、3/3。邀请链接和房间号加入都支持新版进度提示。
- 修正观众状态提示：房主离线时不再误报“没有可用的媒体线路”，服务器连接恢复与媒体恢复也会分别呈现。
- 修正电视内房间号输入界面的居中位置，以及摄像头选择预览被裁切的问题。
- 尚未确认来源声音状态时，不再提前提示“未分享来源声音”。
本次保持现有版本兼容；新版重试进度需要页面与服务端均支持。额外重试不能保证所有网络都能直连。
### English
This maintenance update improves public invitation startup, connection retry feedback, and sharing status messages, with two layout fixes.
- If the public invitation service exits before connecting, Piik retries up to three times within the existing shared 30-second startup budget.
- Enhanced NAT traversal now allows up to three retries after the initial attempt, shown as 1/3, 2/3, and 3/3. Both invitation links and room-code entry support the updated progress display.
- Viewer status now distinguishes an offline host from an unavailable media route, and reports server reconnection separately from media recovery.
- Fixed the alignment of room-code entry inside the TV and cropping in camera-selection previews.
- The missing-source-audio notice now waits until the source's audio availability is known.
Existing version compatibility is preserved. Updated retry progress requires support from both the page and server. Additional retries cannot guarantee a direct connection on every network.
## Problem and outcome / 问题与结果
Add camera sharing and Host microphone commentary to the existing Host workflow,
with shared source cards, device selection, input gain and grouped sharing settings.
Browser and native capture keep one outgoing audio track and the existing room/media
owners. Include optional password-free invitations, public-tunnel protocol fallback,
capture retirement and App-discovery feedback fixes. This is the complete capture
maintenance phase; interaction, x86 capture and 4K experiments are excluded.
## Release notes
### 中文
这次更新让分享多了两种表达方式：用摄像头展示现场，用麦克风边分享边讲解。
分享设置也重新整理，并修复了公网邀请、音视频切换和采集退出中的一些问题。
#### 新功能与使用改进
- **摄像头分享**：在原有选源器中选择摄像头，支持设备选择和画面预览；支持摄像头访问的手机浏览器也可使用。
- **房主麦克风**：浏览器分享和 App 原生采集均可混入房主声音，支持选择麦克风、静音和输入音量调节。观众仍使用原有音量控件收听。
- **更集中的分享设置**：画质、声音和详细连接选项集中在画面下方，常用操作保持直接可用，并调整了窄屏播控与等待提示的布局。
- **邀请链接可选择是否免密加入**：关闭后，链接不再附带免密邀请；接收者按当前站点和房间的准入设置加入。
- **更清晰的启动设置**：可选站点口令默认收起，已有站点地址提供 `demo.piik.tv` 建议，并澄清 NAT 增强选项的含义。
#### 修复
- 公网邀请在 UDP 受限但 TCP 可用的网络中，可使用隧道组件原有的协议回退，减少这类启动失败。
- 调整音频时保留健康的视频发送；修复旧采集事件干扰当前分享的情况。
- 停止或取消原生采集时，先正常释放采集会话，超时才强制退出；修复本地复现的强制终止后 Windows 黄框残留问题。
- 从 App 打开的页面无法连接 App 时，选源器保留明确提示，不再只剩浏览器和摄像头选项而缺少原因说明。
#### 使用说明
摄像头和音频能力取决于系统、浏览器与设备。Windows 仍可能因权限或其他采集要求显示边框。
使用新增的 App 麦克风功能，请更新 App；连接自部署站点时，也请更新站点以获得对应页面功能。
### English
This update adds camera sharing and Host microphone commentary, alongside a
clearer sharing-settings layout. It also fixes several public-invitation,
audio/video transition and capture-shutdown issues.
#### Features and usability
- **Camera sharing:** choose a camera in the existing source picker, with device selection and thumbnail previews. Phone browsers with camera access can share too.
- **Host microphone:** add commentary to Browser sharing or App-native capture, with device selection, mute and input gain. Viewers listen through their existing volume controls.
- **Grouped sharing settings:** picture quality, sound and detailed connection options sit below the picture, while frequent actions remain directly available. Narrow-screen playback and waiting layouts are refined.
- **Optional password-free invitations:** turn this off to copy a link without an invitation credential. Recipients then follow the site's and room's current admission settings.
- **Clearer startup settings:** optional site-password settings are collapsed, the existing-site field suggests `demo.piik.tv`, and the NAT enhancement option has a clearer description.
#### Fixes
- Public invitations can use the tunnel component's existing protocol fallback when UDP is blocked but TCP is available, reducing startup failures on those networks.
- Audio changes preserve healthy video sending. Retired capture events no longer affect an active share.
- Stopping or cancelling native capture releases the capture session before enforcing the shutdown deadline. This fixes a locally reproduced case where forced termination left a Windows capture border behind.
- Pages opened from the App keep a clear connection warning in the source picker when the App cannot be reached, instead of showing only Browser and Camera without an explanation.
#### Usage notes
Camera and audio support depend on the OS, browser and device. Windows may still
require a border because of permissions or another active capture.
Update the App to use its new microphone feature; update self-hosted sites as
well to receive the matching page controls.
## Verification / 验证
- npm run check: 74 files / 1054 tests passed, TypeScript and production Web build passed.
- npm run check:go: Go tests, vet, target builds and Windows native compile/regressions passed.
- npm run gate:app-native-host: actual Windows H264 Host/Viewer, live/paused profile changes,
quiet-source recovery, source replacement/failure, subsequent share and cleanup passed.
- Windows 11 capture-border check: parent cancellation retires the actual WGC session and
clears its border; subprocess tests verify normal, concurrent and timed-out retirement.
- Website build, scripts typecheck, documentation and repository hygiene passed.
- Native macOS/Linux packaging and Linux race checks run in CI before publication.
Physical phone camera and real audio-level/echo/multiple-device coverage remain recorded
limits; the owner authorized release with those limits. No universal NAT/border fix is claimed.
## Impact / 影响
Compatible feature release **v1.6.0**, explicitly approved by the owner. Browser/Server v23,
Native control v9 and capture v7 stay unchanged; new App microphone commands use capability
negotiation. No new dependency, port, media route, room lifecycle or storage migration.
Published Server cutover retains configuration and room storage and uses bounded health
checks with the previous executable available for rollback. Source, tests and owned
documentation ship together; exact artifact/deployment identities remain outside the repo.
## Problem and outcome / 问题与结果
Windows App users can now choose whether to show the capture border. The same border owner handles source previews and active capture; unsupported or denied requests keep normal capture available. The source picker distinguishes an absent/incompatible App, unavailable capture capability, failed enumeration and a genuinely empty list. Chrome's pending local-access permission no longer holds optional Viewer reception.
This phase also reduces tooltip obstruction and contains a failed Linux encoder output within its own branch. Browser/server v23, Native control v9 and capture v7 remain compatible. Closes#401.
## Release notes
### 中文
这是一次分享体验更新，重点改进 Windows 采集边框、App 选源反馈和提示浮窗，并修复 Linux 采集输出的故障隔离。
- **采集边框可选。** Windows App 选源器新增「显示采集边框」，位于声音开关左侧，默认关闭。支持的系统上，来源预览也会隐藏边框。
- **找不到窗口时，提示更明确。** 区分 App 未连接、版本不兼容、采集不可用和读取失败；授权后可以刷新列表重试。改善 Chrome 首次访问时的观看连接，避免本机授权等待拖慢入座。
- **提示浮窗更顺手。** 统一 500 毫秒悬停延迟，减少对画面和控件的遮挡，改善触屏长按和关闭操作；只用于说明的控件使用普通鼠标光标。
- **Linux 分享更稳。** 修复单路编码输出失败可能连带中断其他输出的问题。
- **排查文档更完整。** 补充 App 来源列表、Windows 10 黄框及浏览器 WebRTC 设置的排查说明。
使用新的采集边框开关，请更新 Windows App 并刷新已打开的网页。Windows 10 没有对应的系统接口，边框仍由系统显示；文档中心提供可选处理方法。系统权限或其他采集会话也可能要求保留边框。
### English
This sharing update improves Windows capture borders, App source selection and tooltips, and fixes failure isolation between Linux capture outputs.
- **Choose whether to show the capture border.** The Windows App source picker adds a **Show capture border** switch to the left of audio, off by default. Source previews also hide the border on supported systems.
- **Clearer source-selection feedback.** The picker distinguishes an unavailable or incompatible App, unsupported capture and a failed source list. Refresh after granting access to retry. Pending local-access permission in Chrome no longer delays Browser reception for Viewers.
- **Less intrusive tooltips.** A consistent 500 ms hover delay, improved placement and touch-hold behavior make guidance easier to read and dismiss. Help-only controls use the ordinary cursor.
- **More resilient Linux sharing.** A failed encoder output no longer interrupts healthy sibling outputs.
- **More useful troubleshooting.** The documentation covers App source lists, Windows 10 capture borders and browser WebRTC settings.
Update the Windows App and refresh open pages to use the capture-border switch. Windows 10 lacks the corresponding system API and retains its system border; an optional procedure is available in the documentation center. System permission or another capture session may also require the border to remain visible.
## Verification / 验证
- `npm run check`: TypeScript, 998 tests and production Web build passed.
- `npm run check:go`: Go formatting/tests/vet/target builds and Windows native capture checks passed. macOS cgo builds require their native CI runner.
- Documentation, repository hygiene and website build passed.
- Real Chrome 152 profiles: first-use local permission, recovery after consent and source-list refresh; optional Viewer discovery before/after consent; App Local without cross-address-space consent.
- Public invitation gate: link creation, remote page and WebSocket access, App exit and link retirement passed.
- Windows 11 border on/off, source preview and concurrent-capture checks have physical evidence. Tooltip hover, keyboard, touch-hold, dismissal and narrow-layout checks passed.
- [Candidate CI](https://github.com/TNTcraftHIM/Piik/actions/runs/35157993032) passed at `1d159831`: Server/container, Windows/Linux/macOS packages, Go race checks and frontend validation. Publication was skipped.
- Local Windows ZIP passed packaged startup, capture probing, embedded Web, helper identity/notices and clean-shutdown checks.
- Windows H.264 and VP8 Host gates passed live/paused settings, background recovery, source replacement, source-end/restart, decoded Viewer frames and complete resource cleanup.
- Final `0b370e6a` differs from the CI candidate only in TODO/status closure. Full Web/Go/native checks and website build passed again. The access/privacy gate passed credential-leak and cleanup checks.
## Impact / 影响
Compatible feature update for **v1.5.0**. No wire or storage version change. Older Apps retain their existing capture behavior through capability negotiation. Publication and matching deployments follow the release workflow.
The independent Windows x86 experiment is excluded. Physical 32-bit Windows, macOS/Linux capture, unsupported Windows border control, and actual border-permission denial remain outside this candidate's acceptance evidence. The original missing-window, public-link timeout and URL-handler crash reports still need affected-machine diagnostics.
Waiting feedback and tooltips now share consistent presentation lifecycles, while App shutdown and native-media operation failures stay within their owning session or output. This phase also consolidates the project standards and publishes searchable English/Chinese reader documentation alongside the homepage.
Validation: repository hygiene and Markdown links; TypeScript, 971 Web tests and production build; website/documentation build; Go tests, vet and Windows/Linux builds with Windows capture checks; desktop/mobile UI and documentation review. Linux race, container and three-platform packaging checks run in the release pipeline. Physical macOS/Linux capture and broader network coverage remain outside this acceptance.
The owner approved v1.4.0 publication. Existing empty-source, Windows URL-handler and public-invitation timeout reports remain tracked; this release makes no claim to resolve those device/network reports. The Windows capture-border request is next-phase work.
## Release notes
### 中文
这是一次以稳定性和交互一致性为重点的功能更新。等待与提示更有反馈，App 启动、原生分享和连接恢复的边界处理得到改善，使用与部署指南也有了统一的文档中心。
#### 新增与改进
- 欢迎语、等待短句和六类可轮换的标签页标题共用一致的显示规则。等待短句从一开始就出现，并在停留时轮换；明确的错误与操作提示保持固定。
- 房间准入等漫画采用更克制的小人物与循环动效。改进 tooltip 的定位与指向，减少对播放器的遮挡；状态、图标和文案保持相同含义。
- 新增中英文文档中心，提供搜索、手机目录、使用教程、问题排查与自部署指南。官网 FAQ 聚焦开始使用前的问题，详细排查统一进入文档中心。
#### 修复
- 使用 `--local` 启动不再清空已保存的 Piik 站点地址。
- 打开系统浏览器不再阻塞 App 的退出流程；改进临时公网邀请、终端和诊断导出在关闭时的清理及错误反馈。
- 单条原生媒体连接的操作失败不再被误判为整个会话的协议错误；重复停止分享保持幂等。
- 修复连接替换、转发停止和异常退出时的部分资源清理问题，避免迟到结果影响当前连接。
- Windows 原生采集中，单个输出的编码错误只结束对应输出；共享采集源本身的错误仍会结束分享。
#### 升级与已知边界
本次保持现有协议版本与配置格式。更新 App 或自托管 Server 后，重新打开页面即可使用对应的新界面。
个别设备的空窗口列表、Windows 浏览器启动异常，以及 Linux 编码输出的故障隔离仍在跟进。macOS/Linux 的物理采集和更广泛的公网网络场景仍需实机验证；本次不宣称这些问题已经解决，也不承诺所有网络都能直连。
### English
This feature update focuses on stability and consistent feedback. Waiting states are easier to follow, App startup and native sharing handle several failure cases more reliably, and the new documentation center brings usage and deployment guides together.
#### New and improved
- Welcome lines, waiting captions and six groups of rotating tab titles follow one presentation lifecycle. Waiting captions appear immediately and rotate while visible; actionable errors and instructions remain fixed.
- Room-admission comics use restrained characters and looping motion. Tooltips point more accurately to their controls and interfere less with the player, with consistent meanings across illustrations, icons and copy.
- A new English/Chinese documentation center includes search, mobile navigation, usage guides, troubleshooting and self-hosting. The homepage FAQ covers questions before getting started and links to the documentation for detailed help.
#### Fixes
- Starting with `--local` no longer clears a saved Piik site address.
- Opening the system browser no longer blocks App shutdown. Temporary public invitations, the terminal and diagnostic exports handle cleanup and exit errors more consistently.
- An operation failure on one native media connection no longer becomes a protocol failure for the entire session. Repeated stop-sharing requests are safe.
- Fixed cleanup cases during connection replacement, relay shutdown and unexpected exits, preventing late results from affecting the current connection.
- On Windows, an encoder failure for one native output stops that output only. A failure of the shared capture source still ends sharing.
#### Updating and known limits
Protocol versions and configuration formats are unchanged. After updating the App or your self-hosted Server, reopen the page to use its updated interface.
Empty source lists on some devices, Windows browser-launch failures and Linux output-failure isolation remain under investigation. Physical macOS/Linux capture and broader public-network coverage still need device testing; this update does not claim to resolve those cases or guarantee a direct connection on every network.
## Problem and outcome / 问题与结果
Browser sharing can remain connected to a local encoding transport that never becomes usable, leaving viewers without frames. This phase bounds that startup at eight seconds and restores ordinary encoding through the existing failure path. It also keeps ready App services running after a browser-open failure, preserves user presentation/playback choices, and aligns room feedback, illustrated hints, metrics and documentation.
部分环境下，本机编码连接一直无法建立会让观众收不到画面。本轮在八秒后进入现有降级流程，同时修复客户端启动移交、播放状态和前端反馈的一致性问题，并更新官网与中英文教程。
Closes#399.
Related: #396. The release contains relevant startup/error-handling repairs, but the reporting machine has not been retested. Keep this issue open for a current-build result. #401 (optional Windows capture-border hiding) remains deferred.
Release / 发布版本：**v1.3.1**.
## Release notes

- 统一提示漫画、状态图标与动效，改善选源器还焦、键盘操作、剧场布局和触控目标尺寸。
- 服务端默认支持 20 位观众，可在配置中设为 1–20 位，房主不占观众名额。
- 更新官网、教程入口和中英文说明，清理过时预览及失用代码。
兼容说明：使用旧版 App 连接更新后的站点时，站点会优先保留自己的显示偏好。如需更改语言或主题，请在进入后的页面调整。
### English
- Remember the last confirmed App launch mode and preserve saved language, visual-mode and theme choices during launch handoff.
- Keep the App running if the system browser fails to open, with the page address, retry action and error details available in the terminal.
- Improve the browser sharing startup fallback and avoid treating brief signaling outages as App media failures.
- Keep existing video and local pause state when audio tracks change. Reconnecting and resuming no longer replay the television startup animation over the picture.
- Fix nickname editing and full-name access, remove redundant role hints, and distinguish participant selection from connection state.
- Clarify room access, passwords and invitations. Copy feedback now belongs to the current link and operation, so late results cannot replace newer feedback.
- Correct capture details, metric units and observation intervals. Unknown capture values are no longer replaced with configured ceilings.
- Align illustrated hints, status icons and motion. Improve source-picker focus, keyboard operation, theater layout and touch targets.
- Default the Server to 20 viewers, configurable from 1 to 20. The host does not count toward that limit.
- Update the website, guide links and bilingual instructions, and remove obsolete previews and unused code.
Compatibility: when an older App connects to an updated Site, the Site keeps its saved presentation preferences. Change language or theme on the destination page when using an older launcher.
## Verification / 验证
Non-publishing [CI candidate run 34919320511](https://github.com/TNTcraftHIM/Piik/actions/runs/34919320511) passed Go core, race, Web checks, Server/container verification and all three native App package checks at source 188376e8. Subsequent commits only update deployment documentation, status and TODO; documentation/hygiene checks passed. Product inputs are unchanged.
- `npm run check`: TypeScript, 64 test files / 854 tests, and the Web production build passed.
- `npm run check:client-core`: final Go source passed tests, formatting, vet and core target builds. Windows capture compilation and geometry checks passed earlier in this phase; later edits did not change native capture.
- Website build, documentation checks, repository hygiene and diff checks passed. Existing documentation-size and bundle-size warnings remain.
- Actual browser flows covered sharing, source changes, pause/resume, late audio, brief signaling loss, invitation/copy feedback, entry preferences, source-picker focus, and narrow layouts.
- A local three-viewer P2P relay check covered quality-report expiry, recovery and cleanup without interrupting video. A controlled browser-helper failure returning `0xc0000005` left the real App launcher and Local service available.
- Homepage checks covered Chinese/English, light/dark preferences and inline-film open/close after removing the separate-page entry.
Limits: no new reporter-machine confirmation for #396 or the Windows URL-handler crash; physical Safari/mobile, macOS/Linux capture and wider public-network/endurance coverage remain deferred. Formal release artifacts will be built from the approved squash-merge revision. Hero-loop controls and video-adjacent tooltip placement remain open design items in TODO.
## Impact / 影响
Compatible patch; signaling, Native control and capture contracts are unchanged. Older App launch handoff keeps the updated Site's saved presentation preferences. The Server's default viewer limit is corrected to 20; an explicit 1–20 configuration remains valid.
Service updates retain persisted room authority but restart active media sessions. Deploy the verified immutable Server artifact through the existing bounded health/recovery process. Public Demo remains open and P2P-only; deployment does not enable SFU or change infrastructure/configuration.
Piik now has one public presentation and a coordinated App/Server release path. This phase unifies the room UI, rewrites the bilingual README and guides, adds a static website with an inline product film, and prepares matching GitHub/Gitee packages and update links.
The film uses the current homepage and shared product controls on one seekable timeline. Runtime fixes preserve presentation when the App opens a room, normalize Site origins, and keep capture and media-recovery status in the television indicator. New visits use Chinese for a Chinese system language and English otherwise; explicit language and visual-mode choices remain available. An optional site passphrase controls site entry, while room authorization remains enforced.
GitHub is the release authority. Gitee mirrors verified packages and provides update metadata when GitHub is unavailable. Reviewed PR release notes become the GitHub Release description. The separate public demo uses P2P only, with HTTPS and STUN verified.
Validation: 756 Web tests, TypeScript and production build; Go core tests, formatting, vet and available target builds; bounded Windows capture and App/Site interoperability; browser film checks, audible playback and narrow layouts; anonymous Gitee Windows-package download, checksum and launcher/update-link checks. Public demo acceptance covers authenticated WebSocket signaling, synthetic P2P video and room cleanup on one network. macOS/Linux physical capture and the wider device/network/endurance matrix remain explicitly deferred.
Publication builds every package from the merged source SHA. The repository is public, main protection is active, and Pages is configured for piik.tv. CI/publisher and Pages deployment records own publication results.

Windows App and desktop browsers are the primary validated paths. macOS and Linux have not yet been tested on physical devices; testing and feedback are welcome. The demo and App public invitations rely on P2P and may not connect on restrictive networks. Self-hosted sites can enable media forwarding.
Rename the active product, Go module, binaries, configuration, protocols and documentation to Piik while retaining the TV mascot and existing media/room behavior.
Use one current private contract without old-name aliases. Preserve SQLite authority and copy compatible local settings once; other settings start fresh. Git-message cleanup and the infrastructure name cutover are coordinated with this phase, with original history and deployment data archived externally.
Validated locally with Web and Go checks, Windows capture compilation, matched Client/Server builds, packaged Client control handshake and history-rewrite integrity checks. Skip duplicate hosted CI for this owner-authorized local release.
[skip ci]
* fix: allow Linux interface discovery in embedded media service
* feat: expand local diagnostic reports
* research: validate independent Browser encoding producers
* feat: prototype Browser pool ownership and record remaining media gates
* feat: refine Browser shared encoders and native output reuse
* Refine carrier costs and simplify release entry points
* Close media phase and prepare piik design handoff
Embed STUN and SFU in the shared Go process, reuse native encoding pipelines with independent adaptation, and complete Client lifecycle, settings, diagnostics and packaging fixes. Retain standard Browser senders after measured encoded-reuse limitations.
Complete the Native Client source/audio boundary, strict v5 loopback contract, Browser media lifecycle handling, and non-blocking release checks. Keep unverified platform/physical gates explicit; do not rewrite the Go Server.
Merged after local npm run check, 20-Viewer Chromium loopback gate, and documentation validation. GitHub Actions validation was not started because the repository account billing/spending limit prevented runner start.
Fixes the production-proven P2P-to-SFU quality misrouting. Local full checks and independent P0/P1 review passed; the GitHub job did not start any steps.
Implements the accepted opt-in native-edge local convergence controller and the pre-share topology optimization and peer-only policies. Local full checks and independent P0/P1 reviews passed; the GitHub job did not start any steps.
Modularize durable truth, bound always-loaded instructions, and keep domain-document size checks advisory. Local cross-platform repository hygiene checks pass; GitHub-hosted steps were not started because of the account billing state.
