MediaSource.endOfStream()

The endOfStream() method of the MediaSource interface signals the end of the stream.

endOfStreamError Optional

A DOMString representing an error to throw when the end of the stream is reached. The possible values are:

• network: Terminates playback and signals that a network error has occurred. This can be used create a custom error handler related to media streams. For example, you might have a function that handles media chunk requests, separate from other network requests. When you make an XMLHttpRequest call for a media chunk, and onabort or onerror triggers, you might want to call endOfStream('network'), display a descriptive message in the UI, and maybe retry the network request immediately or wait until the network is back up (via some kind of polling.)
• decode: Terminates playback and signals that a decoding error has occurred. This can be used to indicate that a parsing error has occurred while fetching media data; maybe the data is corrupt, or is encoded using a codec that the browser doesn't know how to decode.

The following snippet is from a simple example written by Nick Desaulniers (view the full demo live, or download the source for further investigation.)

var assetURL = 'frag_bunny.mp4';
// Need to be specific for Blink regarding codecs
// ./mp4info frag_bunny.mp4 | grep Codec
var mimeCodec = 'video/mp4; codecs="avc1.42E01E, mp4a.40.2"';

if ('MediaSource' in window && MediaSource.isTypeSupported(mimeCodec)) {
  var mediaSource = new MediaSource;
  //console.log(mediaSource.readyState); // closed
  video.src = URL.createObjectURL(mediaSource);
  mediaSource.addEventListener('sourceopen', sourceOpen);
} else {
  console.error('Unsupported MIME type or codec: ', mimeCodec);
}

function sourceOpen (_) {
  //console.log(this.readyState); // open
  var mediaSource = this;
  var sourceBuffer = mediaSource.addSourceBuffer(mimeCodec);
  fetchAB(assetURL, function (buf) {
    sourceBuffer.addEventListener('updateend', function (_) {
      mediaSource.endOfStream();
      video.play();
      //console.log(mediaSource.readyState); // ended
    });
    sourceBuffer.appendBuffer(buf);
  });
};
