Dear ffmpeg community, Where can I find more information about the command options? For example, the muxer dash command example is: ffmpeg -re -i <input> -map 0 -map 0 -c:a libfdk_aac -c:v libx264 \ -b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline \ -profile:v:0 main -bf 1 -keyint_min 120 -g 120 -sc_threshold 0 \ -b_strategy 0 -ar:a:1 22050 -use_timeline 1 -use_template 1 \ -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \ -f dash /path/to/out.mpd But I don't know what is each option (i.e. -bf, -keyint_min, -g... etc) and I can't find in the documentation anything about that. Could you please help me? Thank you, best regards.

This is the official documentation with all the subsections combined: https://ffmpeg.org/ffmpeg-all.html (Caveat: Options may be documented without dashes. E.g. "-bf" may not be found as "-bf", but as "bf". That makes it a bit difficult for one or the other option.) Running $ ffmpeg -h full will also get you documentation created "from source". You will need to view the output of that command in a pager or editor, and search, as it is quite a lot, and not meant for reading from front to back. Do consider that some options live in multiple incarnations. If you have more questions, don't hesitate to ask here anyway. Cheers, Moritz

I submitted a patch to address that and to at least make it consistent, but there were disagreements, so the sloppy status quo remains.

Great and thanks. The bug was from me: https://trac.ffmpeg.org/ticket/7740 But I missed the patch, since I'm subscribed to the devel list only since March. -Ulf
