RPI4 Crash while reading mkv file with MMAL Hardware acceleration enabled

  • Hello everyone, I'm looking for help with a raspberry PI 4

    I have just installed my new raspberry Pi 4 with libreelec 9.1.502

    When I try to read a film (mkv through smb) kodi crash every time.


    I noticed that when I disable hardware acceleration MMAL, Kodi won't crash, but instead, my CPU load is very high, and the raspberry overheat quickly.

    Here are my logs

    Thanks

  • I've tried to duplicate your issue but cannot get any sort of crash. I played a .mkv file over SMB without issues.

    I have a feeling it may be the way the file was created/decoded that is causing the problem, Can you provide a snippet of the offending file (IF LEGAL) so we can try and duplicate the issue.

    Yes: If you disable H/W acceleration, then it is decoded in S/W and thus the CPU has to work a lot harder - and WILL get hot,

  • Hello,

    Thank you for your answer.

    Actually, I had this problem with different files.

    Sometime, it happen in less than one minute, sometimes, it's longer (30min)

    Before the crash, I have green artefact on screen, and freeze, before the complete crash

    Maybe it's simply a hardware issue from my Raspberry PI4?

  • Please provide a full debug log.
