I try to transcode with quick sync, but it doesn't work.
I did follow:  https://ffmpeg.org/general.html#Intel-QuickSync-Video

When i use this command:
./ffmpeg -y  -fflags +genpts -loglevel warning  -probesize 10000000
-analyzeduration 15000000 -i
"udp://@:4012?fifo_size=1000000&overrun_nonfatal=1" -map 0:0 -map 0:1
 -strict -2 -dn -vcodec  h264_qsv -preset veryfast -profile:v baseline
-level 3.0 -acodec aac -b:v 1000k -r 25  -b:a 128k -minrate 200k -maxrate
1200k -bufsize 1200k -vf scale=720:576 -aspect 16:9  -ar 48000 -ac 2  -f
flv rtmp://

I get this error
[h264_qsv @ 0x3017580] Error initializing an internal MFX session
Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height

How can I solve this please?
