ExoPlayer can't play mpeg-ts dump

[apptrash]

Hello! There is a dump that cannot be played by ExoPlayer (even with demo application). But VLC for Android, VLC for Linux and ffplay are able to play it. MediaPlayer can play at least video track.

ExoPlayer stops with following exception:

2022-01-13 16:07:38.397 4276-4276/com.google.android.exoplayer2.demo E/EventLogger: playerFailed [eventTime=281.36, mediaPos=0.00, window=0, period=0, errorCode=ERROR_CODE_FAILED_RUNTIME_CHECK

    ]

I know for sure that after transmuxing via ffmpeg, ExoPlayer starts playing the dump normally.

• ExoPlayer version number: 2.16.1
• URI to test content for reproduction: http://stand.netup.tv/downloads/T7609.ts
• Additional: http://stand.netup.tv/downloads/T7609.aux aux file for 'multicat' utility if you wish to test it via UDP
  for example:
  > ls -l
dump.ts dump.aux <-- In the same folder
> multicat -uU dump.ts 239.0.0.1:1234

Tested on:

1. Google Pixel 4
2. Samsung Galaxy S21+
3. Huwaei Honor 9
4. Samsung Galaxy S8+

Can you, please, help me with this dump?
I will provide any information you need.

I can reproduce the problem using the provided TS file. I also see this logged repeatedly before the failure exception:

2022-01-13 16:19:25.282 11206-12000/androidx.media3.demo.main W/DefaultLoadControl: Target buffer size reached with less than 500ms of buffered media data.

@kim-vde could you take a look at this TS file to understand why ExoPlayer is not able to start playback?

You need to set Flag FLAG_DETECT_ACCESS_UNITS in the extractors factory. See https://exoplayer.dev/troubleshooting.html#why-do-some-mpeg-ts-files-fail-to-play for details.

We have an improvement tracked by #7560 to avoid the need for this flag.

Sir, please help i have zero knowledge but I'm trying to understand, sir can you give step by step tutorial to understand where I have to set FLAG_DETECT_ACCESS_UNITS and FLAG_ALLOW_NON_IDR_KEYFRAMES
set on a DefaultExtractorsFactory (where I can find).

@Qhashan, for example

val extractorsFactory = DefaultExtractorsFactory()
extractorsFactory.setTsExtractorFlags(DefaultTsPayloadReaderFactory.FLAG_ALLOW_NON_IDR_KEYFRAMES or DefaultTsPayloadReaderFactory.FLAG_DETECT_ACCESS_UNITS)
val mediaSourceFactory = DefaultMediaSourceFactory(this, extractorsFactory)
val player = ExoPlayer.Builder(this)
     .setMediaSourceFactory(mediaSourceFactory)
     .build()
