Currently i'm using MKVToolNix for my needs which is fine but i would prefer some CLI also. As far as i know ffmpeg supports chapters management.

;FFMETADATA1 - header [CHAPTER] TIMEBASE=1/1 - forcing ffmpeg use seconds START=0 - beginning END=60 - ending title=chapter \#1 - title itself [CHAPTER] TIMEBASE=1/1 START=61 END=120 title=chapter \#2 [CHAPTER] TIMEBASE=1/1 START=121 END=140 title=chapter \#3 – Quintana

ffmpeg -i INPUT -i FFMETADATAFILE -map_metadata 1 -codec copy OUTPUT - Reinserting edited metadata information from the FFMETADATAFILE file – Quintana

Isn't mkvtoolnix a frontend for the command line tool mkvmerge? – Wellman

Answer 1

The ffmetadata format allows you to add chapters to a file.

Have a look at https://ffmpeg.org/ffmpeg-formats.html#Metadata-1 for an example.
