[FFmpeg-user] Rip DVD with ffmpeg

Thu Feb 22 14:59:22 EET 2018

Thanks Steve and ZikZak. I've dumped the DVD with mencoder onto the HDD
but the chapters are still lost. I thought the chapter marks are stored
in Stream #0:0 below but they are not as VLC nor ffprobe don't show them...
I wanted to process the vob-file with ffmpeg afterwards ;)
FYI: I didn't encode anything in this dumping-step in order not to loose
quality.

used commands:
mplayer dvd://11 -nocache dvdnav://11 -dumpstream -dumpfile
~/Videos/movienav.vob
adi at HOST ~/Videos $ ffprobe movienav.vob

I don't understand where the chapter information is stored in the DVDs.
Anybody knows?
@ZikZak: How do you preserve the chapter marks with mencoder dumping a DVD?

I'd preferably use an commandline-tool but as it seems the next step for
me would be to try makeMKV - the newest Linux Version I found ist from
year 2009 - is this correct?
