Exoplayer: IMA Extension video freezes on Huawei: seek to trigger midroll and seek before midroll position

[fpittersacc]

[REQUIRED] Issue description

On Huawei devices with 8.1.0, when playing content with midroll, perform a seek operation that triggers the midroll (see steps below) and then return to a position previous to the midroll position. The video gets frozen while audio keeps playing.

We couldn't reproduce the issue on other Samsung or Xiaomi devices.

[REQUIRED] Reproduction steps

On a Huawei device, modify IMA demo with content & Ad uri shared below.

1. Start the app and let preroll to finish.
2. Seek to a position that triggers midroll (> 15s). Wait midroll to finish.
3. Seek to a position previous to midroll [0 - 15s].
4. Audio playback continues but video is frozen.

• If we don't perform the first seek that triggers midroll and let playback to reach that position the issue is not reproduced.

@fpittersacc Sorry for the long delay. I don't have a Huawei device here to try to reproduce this. It would be helpful if you could check out dev-v2, set ImaAdsLoader.DEBUG = true, try to reproduce the issue using the main demo app (the IMA demo has been removed as it was redundant) and attach a bug report if it's still reproducible. By testing in the main demo app we should be able to tell if video frames are getting dropped based on EventLogger output.

Hey @fpittersacc. We need more information to resolve this issue but there hasn't been an update in 14 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

@fpittersacc Any luck getting the new bug report?

@andrewlewis, sorry for the delay.

We have been checking on Huawei devices and latest 2.11.6 it's performing well on every case.

Thanks, closing!
