I'm new to FFMpeg so this may be a dumb question, but I don't see the answer in the documentation.

I want to decode frames from a DVD vob files. Opening the first VOB in the group works fine, but how do I tell ffmpeg to continue on to the next VOB and read all the VOBs on a DVD?

I have the VOB files in a folder on a hard disk.

VOB format is a subset of mpeg, so you should be able to combine the VOBs you want to read in just as you would mpeg data: by concatenating them together.

cat first.VOB second.VOB third.VOB | ffmpeg -i - outfile.mp4

Hoisting Matt Gallagher's comment to increase longevity/visibility:

Newer versions of ffmpeg support concatenation as an operator on the input file. So you could use... ffmpeg -i concat:VTS_01_0.VOB\|VTS_01_1.VOB\|VTS_01_2.VOB outfile.mp4
