[FFmpeg-user] ffmpeg 4.0 fails to transcoding one 4k clip

[qw]

Hi,


I use the following command, which reports error:


ffmpeg -nostdin -y -hwaccel qsv -c:v h264_qsv -i src_AVC_4K.mp4 -b:a 80000 -ar 44100 -c:v h264_qsv -g 300 -profile:v high -preset veryfast -c:a libfdk_aac -max_muxing_queue_size 4000 -b:v 17418000 -movflags +faststart -strict -3 -vsync passthrough -f mp4 dst_AVC_4K.mp4

Is it a ffmpeg bug?


Thanks!
