I am running Ubuntu 24.04 Noble (Armbian Linux 6.1.115-vendor-rk35xx) and no additional packages affecting VPU performance have been installed; everything is stock. Jellyfin is running in Docker, and transcoding works perfectly, except for some movies.
I tried to play a 4K video in Chrome (native HEVC support), set the bitrate to 40mbps, and the video played normally at a transcoding speed of about 3x, but after a while, Orange Pi crashed. In Firefox inside neko (where there is no hardware acceleration and HEVC), the crash happened even faster, after ~2 seconds of playback.
The crash happens as if the board loses power: journalctl is not saved, nothing is visible via ssh. I use a 100W Baseus GaN Pro Desktop Power Strip (model CCGAN100-1ACE) and the Orange Pi is the only device connected to it. I also have a 100W cable that shows the current consumption in watts. During transcoding, it showed 10, and then the board hard rebooted again, so I don't think this is related to power issues.
Before that, I used Ubuntu 24.04 from Joshua Riek, and there was a problem with the Mali driver crashing under heavy load or simply after a while. A similar hard reboot also occurred if the driver was “too slow” to crash.
Here is Jellyfin's video info:
ffprobe:
I also have a 4 GB model of Orange Pi 5 (not B), and there were no problems with transcoding this video; it was just slow due to the small amount of RAM.
I don't even know where to start. What should I do to at least understand the cause of this issue?
