I tested it with your URL, but I didn't see any errors in logcat. Could you please give me some clues about it?

@himanshu8443 I tested it with your URL, but I didn't see any errors in logcat. Could you please give me some clues about it?

Whenever I play this URL player closes and logs the above error. I don't know if it is a device-specific issue but I am also getting the same error in android emulator. Have you tried it in emulator? And also try changing the audio track

I tested it on the emulator, and it works correctly.

The answer is here : google/ExoPlayer#6525
The mime type is audio/mpeg-L2 which is not mandatory on android device integration. The solution should be to build with ffmpeg (I never try)

[himanshu8443]

ok, I can confirm when I tried playing it without using selectedAudioTrack property video played fine. The error only occurs on using onAudioTracks property and changing the audio track using selectedAudioTrack
by default audio selected is index 1 (audio/mp4a-latm) changing to 'audio/mpeg-L2' causes error
so just adding selectedAudioTrack={{ type: SelectedTrackType.INDEX, value: 0, }} in player properties should reproduce the issue

I tested in some other player that also claims to uses Exo Player it was playing fine that's why I thought its not Exo Player issue may be it is

I reproduce the issue on an exoplayer sample (without ffmpeg). In fact in the sample, the track is grey because it is not supported. Here user cannot identify the track as unsupported. I will add a new flag to be able to track unsupported tracks.
I really think the solution is to enable ffmpeg in exoplayer to be able to play this track...

yes ffmpeg is really needed to provide support on various devices. this is the only blocker i am facing currently.
