TS can't play on ExoPlayer but can on android.media.MediaPLayer

[xuxucode]

HTTP-TS https://raw.githubusercontent.com/edwardaa/aaa/master/exoplay_cannot_play.ts can't play on ExoPlayer, but it can play by using android built in MediaPlayer. I tried it both on Amlogic TV box (6.0.1) and my mobile (4.4).

I am using ExoPlayer r2.0.1.

Hi, this happens frequently when playing HD ts, any progress on this? Thanks for your help.

[gpinigin]

Do your sample have IDR frames? If not - you should alter Exoplayer implementation (TSExtrator) to setup workaround flag in default constructor.

[xuxucode]

@gpinigin Yes, it has IDR frames.

Frames:

[FRAME]
... audio frames
[/FRAME]
[FRAME]
media_type=video
stream_index=0
key_frame=1
pkt_pts=4380960183
pkt_pts_time=48677.335367
pkt_dts=4380960183
pkt_dts_time=48677.335367
best_effort_timestamp=4380960183
best_effort_timestamp_time=48677.335367
pkt_duration=3600
pkt_duration_time=0.040000
pkt_pos=564
pkt_size=235758
width=1920
height=1080
pix_fmt=yuv420p
sample_aspect_ratio=1:1
pict_type=I
coded_picture_number=4
display_picture_number=0
interlaced_frame=1
top_field_first=1
repeat_pict=0
[/FRAME]
[FRAME]
... audio and video frames
[/FRAME]

As your suggestion I changed two places:

• TsExtractor.java#97

public TsExtractor(TimestampAdjuster timestampAdjuster) {
  this(timestampAdjuster, new DefaultStreamReaderFactory(DefaultStreamReaderFactory.WORKAROUND_ALLOW_NON_IDR_KEYFRAMES));
}

• HlsChunkSource.java#374

int workaroundFlags = DefaultStreamReaderFactory.WORKAROUND_MAP_BY_TYPE | DefaultStreamReaderFactory.WORKAROUND_ALLOW_NON_IDR_KEYFRAMES;

It works for this media and other medias that don't have IDR frames! Thank you very much!

But this media mentioned above has IDR frame, I don't know why it can't play normally.

[AquilesCanta]

I will be closing this now. I think the file contains I-Frames, which are not actual IDR frames. We will possibly investigate this in the future, but it's not high priority right now. As @gpinigin said, try using the FLAG_ALLOW_NON_IDR_KEYFRAMES flag.

[needz]

How is it possible to apply this FLAG_ALLOW_NON_IDR_KEYFRAMES workaround in ExoPlayer 2 (preferably during player preparation)? I found H264Reader parameter, but is it possible to do without modifying the library code? Thanks!

[AquilesCanta]

Have a look at DefaultTsPayloadReaderFactory. The constructor's flags argument allows you to set the flag. No library code needs modification.

[needz]

Thanks, I found it, but it seems to be buried deep inside TsExtractor and I can't figure out where exactly I should override it during player preparation. Could you point me in the right direction? Should I override it in buildMediaSource somehow?

case C.TYPE_OTHER: return new ExtractorMediaSource(uri, mediaDataSourceFactory, new DefaultExtractorsFactory(), mainHandler, eventLogger);

[AquilesCanta]

You will need to provide your own ExtractorsFactory(instead of the default one), replacing the default TsExtractor constructor for the one that takes a PayloadReaderFactory. If you know you are going to play only Ts files, you can just provide that one.

[needz]

@ojw28, sorry to bother you, but do you think it's somehow possible to add an easy way to pass FLAG_ALLOW_NON_IDR_KEYFRAMES argument in ExtractorMediaSource or DefaultExtractorsFactory to avoid building complex custom ExtractorsFactory etc., since it's the only thing I have to change in the library for many TS streams to work?
