@Igor Thanks for the answer! So you run the latest Armbian to test? https://armbian.com/boards/orangepi5 from here? Which image? Would using the CLI version also work (I don't need a desktop). Can you maybe also verify if HEVC works? (H264 works also quite okay in pure CPU iirc).

Thanks for the responses! TBH I am not very familiar with the software stack from userspace required for video playback. So, some questions: - @chaitan3: You mentioned using a custom ffmpeg for mpv. Do you know if ffmpeg is also needed for kodi (when just using it to playback videos, not converting)? In https://github.com/mpv-player/mpv/pull/14690#issuecomment-4159253319 you mentioned you used kernel 6.19, but this didn't have mainline support yet, maybe the situation with 7.0 is different? - Does anyone here have a rough idea what is still needed for Kodi (including the whole software stack below) to fully support HW video decoding on said platform (good if you know if specific PRs), without needing custom patches and possible ETA for that?

Hello everyone Just would like to start a discussion about the current state of video acceleration (decoding only, h.265/h.264/av1). The soc (rk3588) recently got mainline support for these features in 7.0: https://gitlab.collabora.com/hardware-enablement/rockchip-3588/notes-for-rockchip-3588/-/blob/main/mainline-status.md Has anyone tested this on a OPI5 already, especially using Kodi? Does this work ootb there now? Regards, XXXBold

Hello everyone I did some more tests now, and most things seem to work pretty good so far. There's one thing that makes watching movies with (not burned in) subtitles a bit a bad experience: Whenever a subtitle is shown, the Image of the video will turn Black and stay black, sound keeps playing normally. This seems to happen every time when a subtitle is shown, so you should be able to reproduce it easily. I found 2 workarounds, but both are not really nice: 1: After the subtitle disappeared, let the movie play for ~15s, then jump back 10s, that will make the image reappear (simple pause-play won't). However, when this is done too often, the stream hangs and the OPI needs a hard reboot (Kodi is no longer responsive), seems the system doesn't like that skipping much. 2: Disable subtitles completely. This is possible but obviously bad for scenes that require them (e.g. native language dialogs etc.). Did anyone experience this aswell, were you able to fix it?
