Comment:
Can you please check the command I used (`ffmpeg -i ./hang_1.mp4 -filter:v
scale=360:-1 -c:a copy -f mp4 -y /dev/null`)? It seems that when
converting to `avi` there is no such a problem; however quite bad when
converting to MOV/MP4. I also found several others that have this issue
(see https://github.com/ntu-sec/pocs/tree/master/ffmpeg-5aeb3b0080/hangs).
All of them took more than 120s to finish.
