    It seems that this particular series is choppy and out of sync. Everything else plays fine. Can anyone shed some light on this?

    Hi !

    I may use this thread instead of opening a new one, since my problem is similar.

    I'm using a RPi4
    I have some problem with Libreelec/Kodi with some stuttering, lags etc etc. After checking all my files and their format thanks to VLC, i may have found the source of those "bugs" and imo it comes from the decoded format, planar 4.2.0 YUV.

    So is there a solution ? Is it a software/hardware problem? Can it be resolved or nah? Just asking, if i can't make it work, i might try my luck on a different OS and use VLC/Others :)

    As HiassofT already stated, the media is 10-bit H264 so the Pi is software decoding it tto 8-bit and doesn't have enough CPU grunt to do this without dropping frames. Nothing supports HW decoding of 10-bit H264 because it is not a broadcast standard, so most people who need this (Animé fans) use a decent Intel x86_64 CPU device that can handle the task.
