When playing (with MPC) some of the MP4/ AVC videos have marks to indicate semantic parts (vertical lines in the timeline).
Is there a way to keep/ insert those separators with avidemux?
I'm sorry, but chapters are not supported.
Thank you! ... nevertheless ... :)
Found out.
It's the metadata:
If one wants to avoid MB-sized GUIs its possible to insert chapters (metadata) with ffmpeg:
https://ffmpeg.org/ffmpeg-formats.html#Metadata-1
Transfer chapters works by:
ffmpeg -i INPUT -f ffmetadata FFMETADATAFILE
To get ALL the streams then:
ffmpeg -i INPUT -i FFMETADATAFILE -map_metadata 1 -vcodec copy -c:a copy -map 0 OUTPUT
However quite uncomfortable if one wants to create new chapters.
