从客户端到服务器的视频流:哪个替代使用，websocket 或 webrtc [英] Video streaming from client to server: which alternative use, websocket or webrtc

问题描述

我希望做几个小项目来试验从客户端到服务器以及从客户端到服务器的多个点的视频和音频流，我有几个问题:

1) 我知道使用 webrtc 从点到点避免服务器中间的硬流传输不是难事，但是可以使用 webrtc 将客户端流式传输到服务器(通过 websocket 这样做有一些好处，或者 webrtc 中的好处是避免中间通信)...流视频和音频怎么样?

使用 websocket 流式传输视频或音频非常简单，但我找不到有关使用 webrtc 流式传输客户端-服务器的任何经验.

2) 将视频流式传输到多个点怎么样，我知道最近有一些 webrtc 实验，因为最初这是不可能的，现在:当它用于 1 到多个点时，webrtc 性能会降低?...流式传输到服务器(可能使用 webrtc)然后使用 websockets 流式传输到几个点会是一个更好的主意??.

非常感谢，请不要粗鲁，我的问题不是主观的或比较两种技术，更重要的是了解哪些是限制以及我可以在哪里使用每种技术......谢谢！

解决方案

Peer2Peer?

可以用 WebRTC 来完成，而不是用 WebSockets.请参阅 websockets 是否允许 p2p(浏览器到浏览器)通信?

浏览器支持?

WebRTC:Chrome + Firefox (+ Opera)

WebSockets:Chrome + Firefox + IE + Safari(+ Opera 和其他一些)

交通?

WebRTC:UDP (SRTP)，(也可能:使用 TURN 服务器的 TCP 模式)希望总是端到端加密，但 我不确定在 TURN 服务器的情况下

WebSockets:TCP，可以通过 HTTPS/WSS 进行保护，但不能在对等点之间进行端到端的保护！

I wish do several little projects experimenting with video and audio streaming from client to server and from client-server-multiples points, I have several questions:

1) I know than is not hard streaming from point to point avoiding server middle using webrtc, but is possible stream client to server using webrtc (exist some benefits doing this over websocket, or the benefit in webrtc is avoid middle communication)...what about streaming video and audio?

Streaming video or audio with websocket is really simple but I can't found any experience about streaming client-server using webrtc.

2) What about streaming video to multiples points, I know than recently there are some experiments with webrtc because originally this wasn't possible, now: the webrtc performance degrade when it is used for 1 to many points?...would be a better idea streaming to the server (maybe using webrtc) and then streaming to the several points using websockets??.

thanks so much and please don't be rude, my question is not subjetive or comparing both technologies, is more related to know which are the limitations and where can I use each one...thanks!.

解决方案

Peer2Peer?

Can be done with WebRTC, not with WebSockets. See Do websockets allow for p2p (browser to browser) communication?

Browser support?

WebRTC: Chrome + Firefox (+ Opera)

WebSockets: Chrome + Firefox + IE + Safari (+ Opera and some others)

Transport?

WebRTC: UDP (SRTP), (also possible: TCP mode with TURN server) hopefully always end-to-end encrypted, but I'm not sure in case of TURN servers

WebSockets: TCP, can be secured via HTTPS/WSS, but not end-to-end between peers!
