ExoPlayer live stream freezes on Askey Android TV box, audio continues

Question

On play-out of some of our own DASH+widevine protected live streams, the video freezes after just a few seconds on an Askey Android TV box (Android 9) while audio continues. I also see video chunks still being fetched. The same streams play successfully on every other Android device we used so far.

After trying several ExoPlayer versions (v2.7.3, v2.9.x), I integrated the play-out code in ExoPlayer's demo player on github (v2.10.5). Here the same problem occurs: video freezes, audio continues.

As other live streams work without issues on the Askey AndroidTV box, the conclusion is probably that the stream's config somehow triggers this issue. But stream config is the same for working/failing streams, and the player logs don't show any clue on why it happens. Except maybe for this error that appears constantly, also when the player is not active:

E libc    : Access denied finding property "persist.vaudio.debug.search"
W HwBinder:3034_1: type=1400 audit(0.0:285045): avc: denied { read } for name="u:object_r:default_prop:s0" dev="tmpfs" ino=13267 scontext=u:r:hal_audio_default:s0 tcontext=u:object_r:default_prop:s0 tclass=file permissive=0

Below is the log of a play-out with video freeze. The freeze happens just after timelineChanged's timestamp 4.34.

The stream has 4 video tracks:

  • 400x224, 0.40 Mbps
  • 600x360, 0.80 Mbps
  • 704x396, 1.10 Mbps
  • 1024x576, 1.60 Mbps

The freeze issue occurs on all tracks, except for the 0.40Mpbs. Here the video continues, but very choppy. In this case logs show frames being dropped:

D/EventLogger: state [773.80, -4.02, window=0, period=0, true, READY]

    ]

Finally, here is a manifest of the freezing stream:
