FFmpeg script for DVD to mp4

[Ghost_Mazal]

Morning all , I want to convert DVD movie to mp4 using x264 and aac. I'm having some issues with GUI apps.

Does anybody have a ffmpeg terminal script to do this ?
I use ffmpeg in terminal for all my single file converts and prefer to use it but don't know how to use it in terminal for a DVD movie to mp4.

Thank you

Handbrake might be the easiest tool to do this. It has a GUI.

Or if you prefer FFmpeg. This example combines two vob files because the movie was split into several vobs.

ffmpeg -i concat:"/media/dvd/VIDEO_TS/VTS_01_1.VOB|/media/dvd/VIDEO_TS/VTS_01_2.VOB" \
-acodec libfaac -aq 100 -ac 2 -vcodec libx264 -vpre slow -crf 24 -threads 0 output.mp4

You'll probably need to compile FFmpeg to use that example:

HOWTO: Install and use the latest FFmpeg and x264

This example probably won't work on an encrypted DVD. See vobcopy (and possibly tccat or mplayer) for that additional step.

Thanx , that example is exactly what I need I knew how to do 1 vob file but didn't know how to combine vob files in ffmpeg.

My ffmpeg is already compiled and working using your guide

Will give that example a go thank you.

Will this work if I am standing in the folder where the .VOB's are ?

 
for f in *.VOB; do ffmpeg -i "$f" -acodec libfaac -ac 2 -ab 128k -vcodec libx264 -vpre fast 
-crf 21 -threads 0 moviename.mp4; done

Or will that just overwrite the output file with each VOB.

Just trying to find a way to make the input a bit easier rather than to specify each input file.

[Ghost_Mazal]

Or this maybe :

 
for f in *.VOB; do ffmpeg -i concat:"$f" -acodec libfaac -ac 2 -ab 128k -vcodec libx264 
-vpre fast -crf 21 -threads 0 moviename.mp4; done

Ok all 3 those scripts of mine was flawed. But with some fiddling this straight forward one works perfect for someone like me who always copies the files to a hdd folder first:

cat *.VOB > moviename.vob; ffmpeg -i moviename.vob -acodec libfaac -ac 2 -ab 128k -vcodec libx264 -vpre fast -crf 20 -threads 0 moviename.mp4

Standing in the folder where the vob files is.

I didn't know you already had the vobs on hard drive. To avoid a large intermediate file you could also try:

cat *.vob | ffmpeg -i - -acodec ...

I believe this is similar to the FFmpeg concat protocol as shown in my earlier example.

[Ghost_Mazal]

Will try that also thanx... (what's the difference between the | and ; ) I'm still very new to the scripting thing.

[FakeOutdoorsman]

The | is a pipe, meaning that cat is giving it's output to FFmpeg instead of outputting to a file. The ; means "do the first command and then do this next command".

And all of a sudden ffmpeg doesn't work anymore After doing a lot of converts with no problems , now suddenly the output file's audio and video is out of sync. Still using the same commands. Now what ??????
