Reproduction steps
player = ExoPlayer.Builder(this).setRenderersFactory(DefaultRenderersFactory(this).setExtensionRendererMode(DefaultRenderersFactory.EXTENSION_RENDERER_MODE_ON)).build()
findViewById<PlayerView>(R.id.playerView).player = player
player.addAnalyticsListener(EventLogger())
val mediaItem = MediaItem.fromUri("https://raw.githubusercontent.com/every-time/samples/refs/heads/main/sample1/master.m3u8")
player.playWhenReady = true
player.setMediaItem(mediaItem)
player.prepare()I'm using the pre-built FFmpeg decoder module from here, which was compiled with ENABLED_DECODERS=(vorbis opus flac alac pcm_mulaw pcm_alaw mp3 amrnb amrwb aac ac3 eac3 dca mlp truehd)
Otherwise, it plays with no video (black screen) AND no audio due to audio/mpeg-L2 being unsupported on my device:

group [
[X] Track:0, id=0, mimeType=video/avc, container=video/mp2t, codecs=avc1.4D001E, res=720x576, par=1.455, color=NA/NA/NA/8/8, supported=YES
]
group [
[ ] Track:0, id=769/4, mimeType=audio/mpeg-L2, container=video/mp2t, channels=2, sample_rate=48000, supported=NO_UNSUPPORTED_TYPE
]
group [
[ ] Track:0, id=769/8219, mimeType=application/cea-608, container=video/mp2t, supported=YES
]
group [
[X] Track:0, id=null, mimeType=application/id3, supported=YES
]
]Expected result
Since the video track should be natively supported by my device, and the audio track is supported through the FFmpeg decoder module, I'd expect ExoPlayer to play both video and audio normally.
Actual result
ExoPlayer plays audio only with a black screen despite logs indicating my device supports all tracks, including video.
