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

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Establish a connection to google cast with our android app - (Receiver app 
gets open on TV)
2. start playing the content from android app.
3.

What is the expected output? What do you see instead?
It should start playing the content as it was playing couple of days back.

We have successfully launched with chromecast support on our app and it was 
perfectly working fine, from the past few days it suddenly stopped working(the 
receiver was alway sending the buffering status to sender and it was 
continuously buffering), i have used the chrome debugging and able to find this 
exception in console "Uncaught NotSupportedError: Failed to execute 
'addSourceBuffer' on 'MediaSource': The type provided ('video/mp2t; 
codecs="mp4a.40.2,avc1.77.31"') is unsupported." in the media_player.js file 
(on the 80th line - according to chrome debugger). not able to understand why 
suddenly this error is thrown, all our customers started complaining that 
chromecast support is not working.

can you please guide me through the problem.

Note: I have used the custom receiver sample from google cast github and 
modified the styling.

we are using HLS for streaming videos: here is the sample m3u8 file content:

I did saw answer to this post: Is avc1.66.31,mp4a.40.2 supported by the 
Chromecast device? but as we have different version of avc codec - avc1.77.31 
don't know, what's the best way to get it working.

What version of the product are you using? On what operating system?

Please provide any additional information below.

The same m348 file, which i have copy pasted here was working few days back, 
seeing this problem around 6th or 7th of july. users were able to cast the 
movies with our app.

again want to mention that saw the similar kind of query on stackoverflow 
http://stackoverflow.com/questions/31256129/is-avc1-66-31-mp4a-40-2-supported-by
-the-chromecast-device and issue no 609.

tried adding this code to player.js file :
 host.processManifest = function(manifest) {
    return manifest.replace(/CODECS=\"avc1.77.([0-9]*)/g, 'CODECS=\"avc1.66.30');
  };

but the problem still exists.

Thanks,
Ramakanth.G

Do you still see the issue when you use 'CODECS=\"avc1.77.30' instead of 
'CODECS=\"avc1.66.30'?
