Bug Description

Hardware accelerated decoding/encoding stopped working at some point in the past on Ubuntu 22.04 with a Radeon RX580 (only used h264 in the past). H264 doesn't show up in the list when connecting to this computer, and when connecting from this computer to another one, UVD usage in radeontop shows 0% and the CPU load is high (due to CPU decoding).

$ vainfo

ffmpeg on the system can still encode and decode video. Tested successfully with the following command, which uses the GPU to both decode and encode video:

ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device /dev/dri/renderD128 -i input.mp4 -c:v h264_vaapi output.mp4
