m3u8 stream can not buffer properly

[s123121]

Describe the Bug Some m3u8 playlist can not be buffer while playing. This lead to undesired behavior: player stop playing after a while (because no buffering) -> buffering -> play -> buffering -> paused. OTOH, the "good" m3u8 playlist buffer while playing so it never stop mid-playing

Steps To Reproduce

https://github.com/s123121/react-native-track-player/tree/test/playlist-paused

I add 2 files in the tracklist. The first one is a"bad" stream, the second one is a "good" stream

How I can Help I can see in Event.PlaybackProgressUpdated logging that the "bad" stream 's buffered value always remains 0, and the"good" stream have the value working as intended

Any solution on this one ?

Try changing this line: https://github.com/s123121/react-native-track-player/blob/test/playlist-paused/example/src/services/SetupService.ts#L10

to

await TrackPlayer.setupPlayer({
  waitForBuffer: true
});

or wait for this pr to be merged: https://github.com/doublesymmetry/react-native-track-player/pull/1695

I did change it to waitForBuffer: true but the problem still persist. Here is the log:

The bad stream:

Both is m3u8 and livestream

Okay just to reiterate, the following stream keeps playing, buffering, playing: https://vnno-pt-1-tf-playlist-live-zmp3.zadn.vn/hpOx2UjqVEQ/zhls/live/standard-audio/855a669d5ad8b386eac9/standard-audio.m3u8

Results of a curl:

While in general m3u8 streams are working as illustrated by the following url: http://113.163.216.23:1935/live/radio1.sdp_audio/playlist.m3u8

I just also experienced this issue listening to the stream on QuickTime player version 10.5.. It did take something like 2 minutes before the audio stopped and buffering started.. What kind of time are you talking about?

[puckey]

So from my experience the first stream just seems pretty choppy - probably due to a slow server?

[s123121]

Probably, there are some codec intervention to prevent others from using the stream. I will close this issue for now until I find other streams with similar problem

@s123121 Thanks – please do get in touch if you are able to pin something down to RNTP being the cause of the issue.
