[FFmpeg-devel] [PATCH 1/2] libavcodec/qsvenc_av1: add av1_qsv encoder

wenbin.chen at intel.com wenbin.chen at intel.com
Thu Oct 13 11:25:23 EEST 2022


From: Wenbin Chen <wenbin.chen at intel.com>

It is available only when libvpl is enabled. MSDK doesn't support av1
encoding.

sample command:
ffmpeg -f rawvideo -pix_fmt nv12 -s 1920x1080 -i input.yuv \
-c:v av1_qsv output.ivf
