Are you specifying any track selection overrides to DefaultTrackSelector, or does this happen just by trying to play the content without doing this? Can you reproduce it in the ExoPlayer demo app?

[DorisGM]

We don't specifying any track selection overrides to DefaultTrackSelector. I can't reproduce by the exoplayer demo app with decoderwithExtensionsDebug (build variant). But i want to know when i build app with withdecoderwithExtensionsDebug ,does it include all video format by ffmepg extensions? Because of I found only when our app include ffmpeg extensions with all video format, the video can't play

[DorisGM]

Thanks for you tips. I found us set track multiple. I'll close this issue
