October 3, 20233 yr Since I re-installed 23.8 Jammy with the extra ppa:liujianfeng1994 repo - I haven't been able to play any videos on my OPI5. All players I tried seem to have kernel issues decoding any h264. I've narrowed down the error message to a 4Gb memory limit with the selected version of the drivers but I was wondering if anyone had luck with playback. I had better luck with Jammy 23.4 and I regret upgrading. What is the recommendation? Should I try nightly with 6.6.0-rc1 kernel? I assume this one doesn't need panfork drivers anymore or are there other recommendations for h264 playback?
October 4, 20233 yr Author I figured out a workaround if anyone else if having this issue. I added the following option in armbianEnv.txt - it will limit your memory to 4gb but fixes video decoding. I believe a real fix for the current 5.10.160 kernel would be an updated version of the panfrost drivers. @amazingfate - any chances you could look into a new build? extraargs="mem=4G"

Without the 4G limitation the playback is choppy (one frame every minute + tons of frames skipped) and they end up with all kinds of weird error messages. mpv shows this one [h264_rkmpp @ 0xffff833fb620] Doing slow software conversion The kernel ends up full of these messages Oct 04 01:51:28 kitchen-opi kernel: rga_mm: RGA_MMU unsupported memory larger than 4G!

October 4, 20233 yr All players based on ffmpeg 4.4 should have this issue. You can try ffplay v6.0: sudo apt install ffmpeg ffplay test.mp4
October 4, 20233 yr Author 2 hours ago, amazingfate said: ffplay test.mp4 Wow yes I can confirm that one works even without the memory limitation. Is there any way to get vlc to use ffmpeg 6? I assume they are linked to avcodec58 instead of avcodec60? I had the video playback working correctly in a previous Jammy version with your previous package. Is the 4Gb memory limit the best solution today? What do you recommend?
October 5, 20233 yr A rebuild of vlc or mpv can use the new libavcodec60 package in ppa. I'm going to upload new packages to trigger rebuild.
October 5, 20233 yr WHile your at it can you create a mesa panfork for lunar? Having only jammy is a bummer. Kinetic dont count nobodys using that interim release.

Million thanks sir! You saved the whole armbian for OPI5, your latest packages work like a charm with VLC - and that is a clean fix. My video playback is perfect again, if not better.
