Investigating. Seems behavior changed in: 4280511a33e961ad18670cb99432cc617ce32dfe

ojw28 commented 9 years ago

ExoPlayer doesn't like the chunklist_b320000.m3u8 variant of this stream. Or chunklist_b256000.m3u8, although the issue is less pronounced. I'm not sure why yet.

The underlying issue exists prior to the change referenced above; it's just that before that change the player wouldn't have switched to these variants.

ojw28 commented 9 years ago

Are you sure the audio is correctly encoded? VLC doesn't seem to be able to play it either. It spews logs like:

Assuming the media is bad. Please re-open if you disagree.

http://music.hdi.cdn.ril.com/mod/_definst_/smil:test/1_2021_2.smil/playlist.m3u8 same url playing fine in mx player and exo player old versions but in updated exoplayer audio streaming getting struck

ojw28 commented 9 years ago

Exact same comments as in the 3rd, 4th and 5th posts in this thread apply to that stream as to the one at the top of this issue. I tried the stream in MX Player, and wouldn't describe it as playing fine. It jumps around all over the place for me, and MX Player spews the following messages about the media into the logs. So yes, I'm pretty sure the media you're trying to play is broken:

so should i replace media content or any solution is there in latest exoplayer lib,changing buffer size or any parameters for playing that content. one more is oldversion of exoplayer lib is playing that content without getting struck why new exoplayer lib is unable to play that content is there any reason for that

ojw28 commented 9 years ago

The reason for the difference is already described in the third post in this issue (i.e. the older version switch up to the higher quality variants of the stream, which are the ones that are broken).

Ideally you should replace the content. Alternatively you can play the initial stream directly, which will prevent the player from switching to the other variants. For the example link above, you can play the initial stream using:
