ffmpeg quicksync not working

[saveli]

When I set GPU acceleration to qsv, ffmpeg can't transcode: 20:09:58 INFO Process C:\Program Files (x86)\Universal Media Server\bin\ffmpeg.exe has a return code of 1! Maybe an error occurred... check the log file

(There's no ffmpeg log file)

What's wrong here?

All the other GPU acceleration options work, but they are worse. We need QuickSync.

@threedguru is this something you're interested in looking at?

QuickSync? Aaah, ok, it is a "new" param for the former one I used - VAAPI for INTEL HW implementaion in FFMPEG 👍 https://trac.ffmpeg.org/wiki/Hardware/QuickSync It will be nice to have INTEL supported as well 👍 Thx!

I mean, it does recognise the supported hardware en-/decoders listed by

qsv

and provides them in the transcoding dropdown menus, but selecting qsv will always crash with error 1.

On a side note, where can one edit the bitrate and so on for these hardware accelerators?

Hardware accel for encoding need a full review on ffmpeg encoding params as each methods have it's own params.
