Newpipe: v20 background playback stops and doesn't recover

Checklist

• [x] I am using the latest version.
• [x] I checked, but didn't find any duplicates of this issue in the repo.
• [x] I have read the contribution guidelines given at https://github.com/TeamNewPipe/NewPipe/blob/HEAD/.github/CONTRIBUTING.md.
• [x] This issue contains only one bug. I will open one issue for every bug report I want to file.

Steps to reproduce the bug

1. Add a few long videos to background queue
2. Maybe lose connectivity after a few minutes (I'm not sure it's the cause)

Actual behaviour

I was playing a long video in background and it stopped after a few minutes. I think it was buffering (notification showed the hourglass instead of the play button).
It never recovered.

I tried jumping to next in queue, but it still stayed on buffering (I don't remember if it switched to next video or ignored the "next video" command).

This could be a different bug - on v19 you could press next when the current video was stuck and it would play the next queued video.

Finally, I exited with the X notification button.

Expected behavior

Background playback should recover from connectivity issues.

Device info

• Android version/Custom ROM version: stock Android 9
• Device model: Samsung S8

_Just installed v20 and this hasn't happened with v19 so I think it's a bug._

_Immediately after, I reinstalled v19 and it played back the same videos with no problems._

If you need more info, please advise on a way that I can contribute further.

Do you know how to capture a log?

[aand18]

@opusforlife2 I'll try to reproduce and have a log

[aand18]

Do you know how to capture a log?

@opusforlife2 No idea :D

I thought there was an option in the menu, somewhere, but I guess not.

[opusforlife2]

Do you have root?

[aand18]

@opusforlife2 no root.

I've reinstalled v20 yesterday and it was impossible to listen to anything of long duration in the background. I'd be really surprised if it wasn't a widespread issue.

I have encountered this issue several times as well. Mostly on my tablet - Teclast T30, stock Android 9.

Same here
Sonx Xperia XZ2c, Android 10

Same here on a Xperia 10 II android 10
It always happens(for me atleast) at exactly 1:04 with at least two videos enqueued. It does not matter what window you have open(be it queue list or off the application completely).
A simple workaround is opening the queue, sending the queue to main or popup player, and just clicking the background icon again. This will fix the issue for the whole queue, it wont happen again unless you fully clear the queue and add new videos.

I tried logging via logcat, but there seems to be no logs from newpipe

@ventilaar: Does your phone have some battery saving thingy? If so, could you try turning that off?

Here is a full adb logcat dump from a LG G6 android 10 custom rom not rooted.

• 22:50:00.970 started application
• 22:50:16.973 background player started
• 22:51:22.619 playback stopped

Getting a very similar problem. If I have more than one video in my background queue, Newpipe will immediately stop loading audio for the background player. It will keep playing anything that's in the cache, but as soon as it runs out it will start buffering and never resume playback. This doesn't seem to be 100% consistent, but I'm having a really hard time identifying what specific set of circumstances cause it to occur or not occur.

Playback won't recover even if I remove all items from the queue except 1. The only way to get the background player going again is to completely empty the queue and then add a singular item back to it.

I can try to obtain a log myself as well, if it'd be useful.

[opusforlife2]

I can try to obtain a log myself as well, if it'd be useful.

Please do. We really need to pin this down.

[Idiotten]

Also have this issue. A majority of the time it stops at 1:04 time, but I've had it in the 2 minutes area before as well. Hopefully I did the log thing correctly. It happened at 9:37.

logcat.txt

I think the 'exact' log where it broke is: "10-16 09:37:59.988"

It shows as a red error and then after that error are a bunch of messages saying "Newpipe tried to update with no new data"

[Stypox]

I tried to extract some infromation from that logcat, here is what I have found.

Up until 09:37:27 there was no activity for more than 30s, so I guess that data before that is pretty much useless. Then some notification updates can be seen:

Then for some reason the MediaSession disconnects from NewPipe and is destroyed, and from then on the playback isn't updated correctly anymore (see PlaybackState {state=0, position=7954, buffered position=7954, speed=0.0, updated=211412333, actions=2364287, custom actions=[], active item id=1, error=null} compared to PlaybackState {state=3, position=1689, buffered position=64644, speed=1.0, updated=211406065, actions=2364287, custom actions=[], active item id=1, error=null} above)

@Idiotten thank you for collecting a logcat. Unfortunately I could only understand roughly what happened, since there is no debug information from NewPipe itself but only from the system. Could you try installing a debug apk and collect a logcat with that? E.g. the one in #4549

[Idiotten]

@Stypox Assuming you mean just do the same thing with that apk, and I don't have to do anything different within settings of that version or something then:

logcat 22-49.txt
On this one playback stopped at 22:49.

logcat 22-53.txt
This one stopped at 22:53.

If I have to do something in the app to capture the log and the above are just the same as the previous one then lmk.

[Stypox]

Thank you! Did you manually open the app at 22:49:21? I assume you didn't. So what happens is basically that Android resumes NewPipe's MainActivity completely at random in the background. The player receives the ACTION_VIDEO_FRAGMENT_RESUMED intent and after a brief second the ACTION_VIDEO_FRAGMENT_STOPPED intent. Probably during this transition something bad happens inside the player, making it not work anymore. @avently do you have some time to look into this? I am unable to work with Android services, service connections and exoplayer ;-)
