This is why browser developers are free to choose what combinations to support. To sum it up, the HTML5 spec doesn’t describe protocols, transports, or codecs.

For instance, H.264 is a standard for compressing huge video frames into small amount of bytes, libx264 is a video compression library that uses this standard, and there’s also eponymous software for Windows that decodes h264 and plays it on the screen. Most streaming services don’t deal with codec-level compression and work with protocols and transports only.īecause the word codec can mean a lot of related things, it’s easy to get confused. Codecs are about compressing the video before streaming, transports are about sending the compressed video over a particular protocol. For example, the RTSP protocol uses RTP transport.Ĭodec actually means a lot of things but in our case it’s a way to compress raw video. protocol) and how the video should be packed (i.e. That is because RTMP’s spec describes both how the communicating parties should interact in order for the video stream to flow (i.e. Notice that RTMP is both a protocol and a transport. container defines how compressed video get packed into bytes for transmission over the wire from one party to another (using some protocol).Įxamples of containers: MPEG-TS, RTMP, RTP. Even when a monstrous petaFLOPS supercomputer connects to a tiny IP camera, the supercomputer is the client and the camera is the server.Ī protocol usually implies at least the Play command (“start playback”), but there can be are others: pause, continue, broadcast, fast-forward, etc.Įxamples of protocols: RTSP, RTMP, HTTP, HLS, IGMP. The stream can flow from the server to the client (video playback) or from the client to the server (broadcasting). The two parties are almost always a client and a server, client being the one initiating the communication. Protocol defines how communicating parties exchange data to receive data. Technically speaking, the HTML5 spec tell nothing about which protocols, transports, or codecs should be used with HTML5 video. It only cares about src pointing to any video stream. The tag doesn’t care how the stream is formed or transmitted, or whether the browser will be able to play it at all. YouTube does HTML video, Twitch does HTML5 streaming. HTML5 streaming is the same thing but when src points not to a complete video file but rather to an ever-updating video stream. HTML5 video is when you put a tag in your web page and set a certain src for it. We’ll tell what kinds of HTML5 streaming there are, which of them are any good, and why, for God’s sake, you can’t say “mp4 streaming.” Glossary In this article, we will once and for all clear up the confusion. It’s hard to blame the customers though: due to confusing terminology, technical complexity, and overwhelming variety of ways to stream video on the web, it’s no big deal to get confused. “The end result is a better viewing experience for our community,” says Twitch product marketing manager Noreen McInnis.Customers often ask us if our server can do “mp4 streaming to HTML5.” In 99% of cases, they don’t understand what they’re talking about.

There’s no word on when the full transition will be complete, though the Flash player will definitely be phased out entirely at some point, likely in 2016, as Google plans to block Flash in its Chrome browser later this year.Īccording to Twitch, the updated video player is among the most-requested features from its users. For those in the beta, HTML5 will be available as an optional feature in the video player.
Today’s beta will only be available to select users, though Twitch says it will open up to more people throughout the summer.
Twitch originally announced its plans to move to HTML5 last year, not long after both YouTube and Facebook made similar transitions.
Today the company is launching a closed beta for its new HTML5 player, which the company says will result in “a smoother streaming experience with faster load times and more consistent delivery of high frame rate broadcasts” compared to the current player. Video game streaming site Twitch is making good on its promise to ditch Flash.
