Is avc1.66.31,mp4a.40.2 supported by the Chromecast device?

问题

I have an m3u8 file that looks like this:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=2048805,CODECS="avc1.66.31,mp4a.40.2",RESOLUTION=1280x720
chunklist_w517510829.m3u8

And I get the following error when trying to play it:

Uncaught NotSupportedError: Failed to execute 'addSourceBuffer' on 'MediaSource': The type provided ('video/mp2t; codecs="avc1.66.31,mp4a.40.2"') is unsupported.
player.js:1682 Uncaught TypeError: undefined is not a function

Strangely enough it plays fine on the Chromecast if I remove avc1.66.31,mp4a.40.2. I am using this sample as a player https://github.com/googlecast/Cast-Player-Sample

Thanks.

回答1:

Some builds of Chromecast reject "avc1.66.31" so it is recommendation to use "avc1.66.30" instead either by updating the playlist or using host.processManifest workaround

host.processManifest = function(manifest) {
  return manifest.replace(/CODECS=\"avc1.66.([0-9]*)/g, 'CODECS=\"avc1.66.30');
};

in a custom receiver.
