Strange freeze behavior when playing videos in the background #8030

Closed silvaDominic closed 2 years ago

silvaDominic commented 2 years ago

Checklist

Affected version

~21.14+

Steps to reproduce the bug

  1. Open a video
  2. Play it in the background
  3. After several minutes the video will freeze and
    • never return to playback
    • return to playback when unlocking the phone or tapping the volume up/down button

Expected behavior

A video should play in the background, possibly buffer, and return to play once buffered without any human interaction.

Actual behavior

Video freezes and does not return playing unless intervening.

Logs

This is not the error log for the above video

Usually this does not produce an error. However, while listening to a fireplace video last night, it did. Unfortunately, I accidentally saved the non-formatted version. Sorry :/

I was able to produce an error on same video stream as above.

Affected Android/Custom ROM version

Android 11

Affected device model

Samsung 10e

Additional information

This started occurring during the same time issue 8029 started happening. I know this because there are 2 routines where I use the background player for extended periods of time:

After the update, I was unable to use the background player for extended periods of time and had to just play it via the video player. Typically what happens is after 2-5 minutes the audio playback will freeze. I will interact with the phone which will immediately resume playback and then playback will continue to freeze every 30-60s.

What is particularly weird is that it does not appear to be a buffering issue. As you can see in the video, playback returns after the phone is unlocked. I was not able to capture it, but it also often returns when simply using the volume up/down keys without unlocking the phone. Mind you, that my internet speed is 300Mb/s in the above video. For the videos I watched on the train prior to the issue, my connection was significantly slower than this, relying only on data and I still never had this issue.

Seeing as your phone is a Samsung device, have you made sure that it's not just the system killing the app in the background?

See this for info: https://dontkillmyapp.com/samsung#android-11

@TacoTheDank Wow just tested it and this fixed the issue. I also tested with a Sony device and the issue was not present.

This is the line from the link you provided that gave it away:

"Despite Android team promise to enforce OEMs to be transparent about non-standard app killing, in Android 11 Samsung has introduced a new severe (default ON) restriction. Apps can no longer hold wake lock in foreground services. This breaks many use-cases, for instance health apps are now unable to gather sensoric data for their users."

Within the same week as the update that created bug #6989 I had installed a new major Samsung update. I suspected that could have something to do with it, but given that the only app affected was NewPipe, and that there was already another issue, I associated it with that update. I also didn't have issues with other services playing in the background like Pandora/Spotify so that led me to believe it was even less to do with the Samsung update.

Great tip and thanks! I can finally use the main feature I got NewPipe for lol.

Closing.

Issue was caused by Samsung update turning on battery optimization by default for all apps. This explains why playback would resume on wake/phone interactions.

I have a Samsung device too (albeit running Android 10), so I know this problem a little too well.

Glad I could help! :)
