## 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 ### 中文 - 客户端记住上次确认的启动模式；启动移交保留已保存的语言、纯视觉模式和主题选择。 - 系统浏览器未能自动打开时，客户端继续运行，并在终端保留页面地址、重试入口和具体错误。 - 改善浏览器共享画面的启动兜底，避免 App 媒体因短暂信令中断被误判为失败。 - 音轨变化保持现有视频与观众的本机暂停状态；连接恢复和暂停恢复不再重复播放电视开机动画。 - 修复昵称编辑及长昵称查看，减少重复的角色提示，统一人物选择和连接状态的区别。 - 完善房间准入、密码和邀请说明；复制反馈对应当前链接及当前操作，避免迟到结果覆盖新反馈。 - 修正采集参数、统计单位与采样区间的展示，未知参数不再用配置上限代替。 - 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.

Features
- Watch without installing. Friends join by invitation in a desktop or mobile browser.
- Share from Piik App or an existing Piik site. Capture a screen, window or browser tab; available sources and audio depend on the platform.
- Direct connections first. Media travels between participants where possible (P2P). A self-hosted server can provide automatic media forwarding (SFU) as a fallback.
- Rooms you control. Invitations, room codes and optional room passwords, for one host and up to 20 viewers.
- Flexible viewing. Light and dark themes, playback controls, picture-in-picture and a connection topology view.
- One program to host a site. Web UI, room management and optional media forwarding are packaged together.

Get started
To watch: open the invitation your friend sends you. Select Play if the picture does not start automatically.
To share: download Piik App to get started. To share without installing, you can also create a room in the online version.
| Start here | What you need to do |
|---|---|
| Use Piik online | Open it in a desktop browser to create a room and share. |
| Download Piik App | Extract and open the App, choose Public invite, then Open Piik to create a temporary room. |
| Use an existing Piik site | Open the address your friend or administrator provides. Hosting your own is an advanced option. |
- Select Start sharing, then choose the picture and audio to share.
- Select Copy invite link and send it to your friends. Keep the sharing tab open.
Piik follows your system language: Chinese or English, with English as the fallback. Use 中 / EN / ✦ in the header to switch language or try the visual mode. The App offers a local room, a temporary public link, or a connection to your own site. Keep the App running while sharing through it.

Browser capture requires HTTPS or localhost. Windows App and desktop browser
sharing are the primary tested paths. The macOS and Linux apps have not yet been
tested on physical devices; test results and feedback are welcome.
P2P-only modes, including the App's temporary public
link and the online version, may not connect on restrictive networks.
Self-hosting
Piik Server is a standalone binary with the web interface built in.
Download the Linux x64 Server package (piik-<revision>-runtime.tar.gz),
extract it, and run:
./piik-server
Open http://localhost:8787 to try it locally. For a public site, configure your
domain, HTTPS reverse proxy and STUN address. Room data is stored in SQLite.
For containers, use the Docker Compose setup.
