    I think the stutter with hardware decoding disabled is due to the slow cpu-performance.

    It is not a bug and it existed also on the previous versions of libreelec and kodi.

    So no reason to complain with hardware decoding disabled.



    DaVu

    Matching refresh rate is missing 25Hz, 29,97Hz and 30Hz.

    Theses are accomplished with framedoubling, so the system uses 50Hz an 60Hz. (nearest match)


    and here goes something wrong, wich worked fine in the previous versions of libreelec or kodi.


    DaVu

    what platform are you using?



    i don't have 30fps material, it would be interesting to find out if it also stutters, if so, it should have something to do with framedoubling.

    Here is a second log, this time i put in

    Code
    <advancedsettings>
        <loglevel>1</loglevel> <!-- Change this to "1" to hide the on-screen debug log text -->
    </advancedsettings>


    that means no overlay while video-playback, and my 25fps video stutters.

    The feeling is that at least every second frame is not displayed or delayed.


    Since displayrefresh rate is 50Hz i can't be shure which of two possibilitys happens.

    possibility a) every second frame of the videofile is droped, that means on a 50Hz display refreshrate i get a new picture every 4 frames.

    possibility b) the frames are not evenly distributed to be shown every two frames, instead this could be happening:

    videoframe 1 is schown on refreshrateframe 1

    videoframe 2 is schown on refreshrateframe 2, 3 and 4

    videoframe 3 is schown on refreshrateframe 5

    videoframe 4 is schown on refreshrateframe 6, 7 and 8

    videoframe 5 is schown on refreshrateframe 9

    and so on.

    I think the log will not provide any answers because while logging with overlay it does not stutter


    Here is my log:

    All videos (24fps, 30fps and 60fps) are playing fine, only files with 25fps are stuttering since libreelec 9.0


    If there are overlays like when skipping back, media info, or if i activate debugging with an overlay in the upper left corner, the stuttering is gone.


    Also if i switch to software decoding the stutter is gone.


    With libreelec 8.2.5 and older everything works fine.


    I'm running libreelec on NUC DN2820FYKH
