Intel QSV transcode error - honofre - 2025-04-07
Hi all,
I have been trying to activate video transcoding on a N150 server with Debian OS and after some research, I suspect that the problem is related to the ffmpeg command.
When I try to transcode any file, I get the following error in the web gui:
La reproducción falló por un error fatal del reproductor.
Which translates to: Fatal Error has Occurred
The following error raises in FFmpeg.Transcode-2025-04-07_10-59-46_1eed8ccc38725d0b59c7ba57bfba8f0e_c9058753.log file:

Error opening output file /dev/dri/renderD128,driver=iHD.
The ffmeg command run is the following:

I think there is a problem with a space that shouldn't be there (after the
:vaapi=va: /dev/dri/renderD128,driver=iHD
If I run the command as root, /dev/dri/renderD128,driver=iHD is created. If I run the same command without that space, it seems to run well.

RE: Intel QSV transcode error - TheDreadPirate - 2025-04-07
Can you show me a screenshot of Dashboard > Playback > Transcoding? Based on the ffmpeg command from your log, it looks like you put /dev/dri/renderD128 in the QSV device field. This field should be blank since you only have one Intel GPU in your system. IIRC, if you did have more than one Intel device you would put the index number for the desired QSV device. Like 0, 1, 2, etc.
/dev/dri/renderD128 would only be used for VAAPI.
When the QSV device field is left blank this is what is populated in the ffmpeg log and works properly.
Code:
vaapi=va:,vendor_id=0x8086,driver=iHDRE: Intel QSV transcode error - honofre - 2025-04-07
Hi @TheDreadPirate,
That made the trick, I have changed the QSV Device from "/dev/dri/renderD128" to "" and now it's working perfectly!
Thanks for your help, you made my day!
