[FFmpeg-user] More information about command options

[Jesús Aguilar Armijo]

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.
