Живой эфир ExoPlayer останавливается на Askey Android TV box, звук продолжается

0 голосов
/ 16 октября 2019

При воспроизведении некоторых из наших собственных потоков прямой трансляции, защищенных DASH +, видео останавливается через несколько секунд на Askey Android TV box (Android 9), а звук продолжается. Я также вижу фрагменты видео, которые все еще загружаются. Те же потоки успешно воспроизводятся на любом другом устройстве Android, которое мы использовали до сих пор.

После нескольких версий ExoPlayer (v2.7.3, v2.9.x) я интегрировал код воспроизведения в демонстрационный проигрыватель ExoPlayer наgithub (v2.10.5). Здесь возникает та же проблема: видео останавливается, звук продолжается.

Поскольку другие живые потоки работают без проблем в окне Askey AndroidTV, можно сделать вывод, что конфигурация потока каким-то образом вызывает эту проблему. Но конфигурация потока одинакова для рабочих / неудачных потоков, и журналы проигрывателя не показывают, почему это происходит. За исключением, может быть, этой ошибки, которая появляется постоянно, даже если плеер не активен: 

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

Ниже приведен журнал воспроизведения с остановкой видео. Заморозка происходит сразу после временной отметки timelineChanged 4.34.

Поток имеет 4 видеотрека:

  • 400x224, 0,40 Мбит / с
  • 600x360, 0,80 Мбит / с
  • 704x396, 1,10 Мбит / с
  • 1024x576, 1,60 Мбит / с

Проблема замораживания возникает на всех дорожках, кроме 0,40 Мбит / с. Здесь видео продолжается, но очень изменчиво. В этом случае в журналах показываются пропущенные кадры:

Наконец, вот манифест потока замораживания:
