Player get stuck with particular h264 stream

[vitekn]

I am trying to play multicast stream encoded with h264.The player versions are 2.0.1 - 2.0.3. The only message from player is STATE_BUFFERING and nothing else happens. I recorded this stream to file and checked it again streaming with ffmpeg -re -i file2.ts -c copy -f mpegts udp://235.10.20.6:1234, but the result is the same. If I transcode this stream like ffmpeg -re -i file2.ts -c:v h264 -f mpegts udp://235.10.20.6:1234 it plays fine.

I have tried it on 2 android stb Vermax HD100 and MXQ.

Handler mainHandler = new Handler();

TrackSelector trackSelector = new DefaultTrackSelector(mainHandler);
LoadControl loadControl = new DefaultLoadControl();
pl = ExoPlayerFactory.newSimpleInstance(ctx, trackSelector, loadControl);
DataSource.Factory udsf = new UdpDataSource.Factory(){
@Override
public DataSource createDataSource() {
return new UdpDataSource(null, 1500);
}}
videoSource = new ExtractorMediaSource(uri, udsf, TsExtractor.FACTORY, null,null)
pl.setPlayWhenReady(false);
pl.prepare(_videoSource);

The recorded stream appears to have no IDR frames. Try setting FLAG_ALLOW_NON_IDR_KEYFRAMES to treat non-IDR I frames as synchronization samples. This makes the video play on my test device.

See also #1894 and #1660 which are similar.
