I use the above command to do transcoding, but output's video is incorrect.
The source file can be downloaded from http://u.163.com/N3GUSNJN, and password is IeIZuu4M.
but the following command results in correct output's video:
ffmpeg -init_hw_device qsv=hw -filter_hw_device hw -i "4k_ffmpeg_h264_20m.flv" -acodec libfdk_aac -profile:a aac_he -ar 44100 -ac 2 -ab 64000 -vcodec h264_qsv -vb 20000000 -r 25/1 -force_key_frames "expr:gte(t,n_forced*5)" -minrate 20000000 -maxrate 30000000 -bufsize 40000000 -preset veryfast -profile:v high -vf "format=nv12, vpp_qsv, hwupload=extra_hw_frames=64,format=qsv" -vsync 1 -async 1 -max_muxing_queue_size 2000 -threads 16 -f flv 4k_ffmpeg_h264_qsv_debug.flv
