Widevine DASH streaming does not start

[ogawa-ma]

■ Question
I have publishing an application using ExoPlayer, but streaming playback does not start for some users.
Playback does not start even after 1 minute after setMediaItem and player.prepare().
When this event occurs, if the user can't wait and ends playback, player.release() is called in onPause of the playback screen class, but an error occurs there.
Can you tell from the log why playback is not possible?

• 2.16.1

■ Some of the devices that are occurring

• Pixel 4a (5G)(OS version 12)
• arrows NX9 F-52A(OS version 12)
• Xperia 5(OS version 11)
• Xperia XZ3(OS version 10)

■ Android version in which this is occurring

• 5~12

■ Playback Video Format

• Widevine DASH (H.264)

I have sent the media file URL and the license server URL to dev.exoplayer@gmail.com.

@ogawa-ma I tried playing the media file sent via email and was able to play it successfully on Pixel 4a (5G) running Android 12.

This exception occurs when one of the renderers times out releasing its resources.

Without being able to reproduce I'm afraid there's not much more help we can offer.

@rohitjoins

This exception occurs when one of the renderers times out releasing its resources.

In what cases does the renderer time out on releasing resources?

[rohitjoins]

@ogawa-ma I believe #10621 and #10610 is related to this issue. I have closed the other two issues in favour of this.

So the main issue seems to be the MediaCodec exception that you get on the device, which in turns doesn't allow the player to release its resources properly as it is not in a defined / known state.

I'll try to find a way to recover from such exceptions and update you on this ticket.
