chromecast - Google cast receiver throwing "Uncaught NotSupportedError: Failed to execute 'addSourceBuffer' on 'MediaSource' -

we have launched chromecast support on our app , working fine, past few days stopped working(the receiver alway sending buffering status sender , continuously buffering), have used chrome debugging , able find exception in console "uncaught notsupportederror: failed execute 'addsourcebuffer' on 'mediasource': type provided ('video/mp2t; codecs="mp4a.40.2,avc1.77.31"') unsupported." in media_player.js file (on 80th line - according chrome debugger). not able understand why error thrown, our customers started complaining chromecast support not working.

i did saw answer post: is avc1.66.31,mp4a.40.2 supported chromecast device? have different version of avc codec - avc1.77.31 don't know, what's best way working.

note: have posted same question on g+ community, update answer there if find working solution here. thanks.

try replacing codec avc1.77.30

host.processmanifest = function(manifest) {   return manifest.replace(/codecs=\"avc1.77.([0-9]*)/g, 'codecs=\"avc1.77.30'); };
