Hi， IG-88，
my board is j4105.
DSM version 6.2.3 25426
extra.lzma v0.13.3
I tried to transcoding some videos with hardware acceleration and found that it didn't work
the result video size is very small, and no video frame in it, just only audio data. I try transcoding command line(same MOV format video), get the same result.
Partial transcoding log(return video:0kB audio:159kB)：
[aac @ 0x564733e9ef00] Trying to remove 128 more samples than there are in the queue

Transcoding Command Line:
ffmpeg -y -report -init_hw_device vaapi=foo:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device foo -i input.mov -filter_hw_device foo -vf 'format=nv12|vaapi,hwupload' -c:v h264_vaapi -b:v 10683833 output.mp4
the /dev/driv/ is normal，
and the driver is normal
Everything looks normal, but it just doesn't return normal results, I found an error in a section of log in DMESG, I don't know whether it is related to this, please help to confirm whether this section of log indicates that the graphics card has been driven normally
