FAQ常见问题

Good to know.你可能
还想知道。

Do I need my own server?需要自己搭服务器吗?

No. Try the online demo, or choose Public invite in Piik App to create a temporary room. You can also use a Piik site provided by someone else. For a permanent site under your own domain, follow the self-hosting guide. 不需要。可以直接体验在线 Demo,或在 Piik App 中选择公网邀请创建临时房间,也可以使用别人提供的 Piik 站点。想用自己的域名长期运行一个站点,再看部署指南。

Does everyone need Piik App?每个人都需要安装 Piik App 吗?

No. Friends watch in a desktop or mobile browser without installing anything. You can host from a supported desktop browser on an existing Piik site, or use Piik App to create a room.不需要。观众用电脑或手机浏览器就能看,无须安装。房主可以在已有 Piik 站点上,用支持屏幕共享的电脑浏览器开始分享,也可以通过 Piik App 创建房间。

How many friends can join?最多能叫多少朋友?

One host and up to 20 invited viewers fit in a room. Piik is made for a private group hanging out around one screen.一个房间支持一位房主和最多 20 位受邀观众。叫上熟悉的朋友,看看游戏、演示作品,或者围观彼此的新发现。

Can I share sound too?声音也能一起分享吗?

Yes, when the selected source and capture method support audio. Check the sound option when choosing what to share. Browser and operating-system support varies; viewers may need to press Play and turn on the video’s sound.可以,前提是选择的画面来源和采集方式支持声音。选择分享内容时,检查声音选项。浏览器和系统支持有所不同;观众可能需要先点播放,再打开视频声音。

Can we watch from different places?不在同一个地方,也能一起看吗?

Yes. Use the demo, an Internet-accessible Piik site, or Public invite in the App. Public invite gives your room a temporary address that can change or become unavailable; closing the App ends the room. The demo and Public invite use direct media connections without server forwarding, so some networks may load the page but block the video. You can also use a Piik site with media forwarding enabled for a fallback connection.可以使用在线 Demo、能从外网访问的 Piik 站点,或客户端的“公网邀请”。公网邀请的地址是临时的,可能中断或变化,退出 App 后房间也会结束。 Demo 和公网邀请的画面靠设备间直连传输,没有服务器转发兜底;部分网络可能出现页面能打开、画面连不上的情况。 也可以使用已启用媒体转发兜底的 Piik 站点。
