The error is from trying to open an MPEG5 (h256) stream, which is not supported by the HW decoder on the RPI. Do you get a similar problem when playing an MPEG4 file ?

@mitu I downloaded and tried one such MP4 video for testing; it ran without any problems.

I also played a new retropie system on another memory card and just installed KODi directly, the error was still there with said video.

As I said, this video runs on an old Retropie system with Kodi 18.2 without any problems. If necessary, is it somehow possible to install an old version of KODi and remove the current 18.7?

No, I don't think so.

@mitu Not sure... I kept my old OSMC (latest) image (fresh install, setup and backuped) including OMX player for my Pi3s for future use, I am not sure what repos for Kodi/arm are available/kept, but for me (and no, I am not able to do it) it sounds like a <core_of_choice_state/year_of_legacy> option..?.. And maybe, if there are people able and willing to setup such a pi3/retropie-legacy fork, it could be possible after all ?

@Turrican2k best option, if you really want to use HEVC Videos with a Pi3 in Kodi/Retropie, is to find the people which are able to create such an install/fork.

P.S.: ... For me I never understood why Retropie included Kodi, or my Kodi based OS of choice (OSMC) included emulators (mixing purpose and context).
P.P.S.: But that is just me and I never was a fan of "suits" and always prefered single solution/context apps/programms (Edit: bloody me, why am I using retropie/libretro at all on the pi? dough? Sigh...).

Edit: Ok, forget about that thought -> as I had forgotten that HEVC decoding on the Pi3 is due to OMX Player, and as that one (sadly as it is) is decapricated under bullseye (and AFAIK only works under fkms, not kms), such a repo would just be another dead-end :/

You're confusing HEVC with MPEG. The Pi3 doesn't have any HEVC (MPEG5) HW decoding/encoding capabilities, this was added on the Pi4 hardware. The Pi4 also doesn't have HW MPEG decoding, which is largely unnecessary on the PI4's CPU.

@mitu Nope ;), even if the Pi3 had no HW Decoding for HEVC, MMAL/OMX somehow utilized parts of the existing HW-Decoding capabilities for h265 Playback. With Leia I have no playback issues for 720p/1080p HEVC content (most encoded via x265 with preset medium/crf 16) on my OSMC install (Pi3B+), with later versions that is a nogo.

Edit: In the time of the introduction of Matrix, posts like this one from pi3 users where emergent.
Edit2: Ok, and maybe my memory served me wrong and it wasn't due to MMAL/OMX but a modified ffmpeg-version applying the magic (together with MMAL?).

As I said, in an old version, videos are displayed smoothly on the RPI3, which no longer works in the new version. Does anyone know where exactly KODi is installed under Retropie? Then I could copy KODi from my old Retropie version to a stick and overwrite it on my new Retropie version (?).

i think the path for kodi is this /opt/retropie/ports
