[FFmpeg-user] how to use Intel qsv codec for ffmpeg 4.0

[Li, Zhong]

Looks like qsv transcoding on system memory is broken. 
Would you please create a ticket on https://trac.ffmpeg.org/?

And for you case, switching to full hardware path is benefit to performance.
Try: ffmpeg -hwaccel qsv -vcodec h264_qsv -i input-file -acodec aac -ac 2 -b:a 48k -vcodec h264_qsv -b:v 2000k -vf " scale_qsv=960:720" -g 25 -r 25.0 -f flv output-file
