I’ve been playing around with ffmpeg trying to get the proper parameters for the best quality using intel qsv. One desktop (Intel UHD 630 version 27.20.100.9168) I get the following error:
[hevc_qsv @ 0000018e9a302e00] Could not load the requested plugin '6fadc791a0c2eb479ab6dcd5ea9da347': specified object was not found (-9)
[hevc_qsv @ 0000018e9a302e00] Error loading plugins
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
But works fine on another desktop (Intel Iris Pro 580 version 27.20.100.8681). I am using the included ffmpeg but am running the job manually via command prompt. Here is what I’m running:
ffmpeg.exe -hide_banner -threads 0 -hwaccel qsv -i D:\Temp\input.mp4 -vf yadif=0:-1:1,hqdn3d -vcodec hevc_qsv -preset slow -crf 26 -vsync 2 -map 0:v -sn -acodec copy -map 0:a -f matroska c:\Temp\output.mkv
Anyone know how to resolve this error?
