FFmpeg 6 taking more time than FFmpeg 5 for dash file generation
9 mars 2023, par QCoderI tried to generate a MPD file along with the audio and video stream files using the dash muxer in FFmpeg. This is the command I am using :


ffmpeg -y -i video.mp4 -f dash mpd_file



I tried it on 34 min video. For FFmpeg [5.1.2] it took almost 2min 10 sec to generate everything and for FFmpeg [6.0] it took about 4min 41 sec. Amost double the time.


I tried trimming also and for that also the time comparison was almost same, FFmpeg 6 took double the time than that of FFmpeg 5.


What could be the possible reason for it ? Am I missing some flag for FFmpeg 6 or is there any new addition ? Because when I checked the release notes of FFmpeg 6, there was no new filter which was added related to this particular case.


I tested this comparison on the same machine and it is very unbelievable that FFmpeg 6 is taking so much time, considering this is a new and an advanced version of FFmpeg 5.
