Flutter Android TV: app crashes when loading streams quickly one after another
I created a test app for Flutter on Android TV that can play external streams via a streamingUrl. Initially loading the stream and playing it works fine.
The problem starts when I want to 'zap' through the different streams that are available by using the channel up/down buttons on the remote control. When doing this often, at a certain point the app will crash giving me nothing more than a 'tombstone' with a vague description of what went wrong.
I already tried the Flutter profiler to check if it is memory/performance related, but so far that does not seem to be the problem.
Also: there are devices with varying hardware specs on which this problem never occurs.
I'm using the Android Media3 library with some customizations to play the stream and handle DRM cases. So the playing of the stream is handled natively.
It seems that the Skia rendering engine wants to render a frame, but fails to do so, causing a crash at some point. But why and how this is happening is still a big mystery to me.
Can anyone help me by pointing me in the right direction to solve this issue, by answering one of the following questions:
- Is this a known issue?
- Could it be caused by the Flutter rendering engine?
- Will Impeller maybe solve this issue, and should I just wait until that is released?
- Other pointers would be great as well!
The tombstone's stacktrace starts with this line:
2024-01-24 14:49:16.152 29103-29103 DEBUG crash_dump32 A signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0xe675b014
The last method that was called and is readable looks like this:

The solution was to use a lower quality stream. Apparently some devices don't like it when you feed them a high quality stream. So downgrading to 720p fixed the issue on the devices I'm currently testing on.

Had a similar issue and the problem was that I was not releasing the player (calling player.release()) after each zap.
You say it's not a memory problem but may be give it a try.
