extra_hw_frames is needed for some cases. (eg: qsv decoding + qsv vpp + qsv look_ahead encoding, transcoding failed if no extra_hw_frames supported: ffmpeg -hwaccel qsv -c:v h264_qsv -i bbb_sunflower_1080p_30fps_normal_2000frames.mp4 \ -vf vpp_qsv=w=1280:h=720:extra_hw_frames=100 -v verbose -c:v h264_qsv \ -look_ahead 1 -look_ahead_depth 100 out1.mp4 ) Signed-off-by: Zhong Li <zhong.li@intel.com>
