(RPi4] LIVE-TV non-fluid playback after 4e4a6f9

    LIVE-TV non-fluid playback after 4e4a6f9


    I've been using tvheadend to watch live-tv with libreELEC.

    Up to LibrEELEC 13 compile for 01 feb 2025 (4e4a6f9) all was ok.


    Compilations made after that one gives me non-fluid play back - noticed mostly in full screen panes (left-right or right-left).
    Perceived mainly in sports (football, or sports cars races).

    Every compilation I've tried up to 1st July has he same symptoms.
    Going back to 4e4a6f9 works just fine.

    I've tried to understand what's happening by looking into source code changes but without success.
    Anyone else with similar issues or suggestions on how to trace and solve ?

    I don't believe that my configuration poses an issue as it is the same for every test i've made, but here it goes:

    - Raspberry Pi4, 4GB RAM
    - tvheadend 4.3
    - PAL-HD TV channels (Western Europe)
    - SONY android TV
    - HDMI connection
    - 1920x1080 resolution
    - 23.976, 25, 29.97, 50, 60 fps playback unlocked


    Thanks

    To avoid ambiguity, are you saying a build you make from commit 4e4a6f9 is good and the very next commit (a794735ee) is bad?

    Or are you testing official nightly builds (which may jump a few more commits).

    I'm not sure exactly when the issue started.

    It was after 4e4a6f9 , but don't know exactly which commit started with issues. I've tried several, but was not able to find exactly which one.

    I might try a794735ee if you think it would help (which should have pvr addons changes only - but not for the tvheadend pvr client).


    Thank you
