(FFMPEG) Concatenateing VOB files, no audio problem

[Simon_]

Hello, i am looking to merge 2, or more VOB files, in FFMPEG from the same source (a home made DVD)

I have used the code below:

ffmpeg -i "concat:VTS_01_1.VOB|VTS_01_2.VOB" -f mpeg -c copy output.mpg

However when i play the output.mpg in VLC there is no audio. Both original VOB play in VLC with the video and audio working fine.

I am new to FFMPEG and so i need to know how i can convert the audio into a playable format whilst retaining a high audio quality.

Thanks for your help.

Try vobmerge. Or use the command line copy /b vts_01_1.vob + vts_01_2.vob joined.vob and see if it works better.

Or vob2mpg and see how it works.

is there a way to merge vob's in FFMPEG? so.. VOB +VOB = VOB

[aedipuss]

you were given 3 answers that will work with vobs that have identical specs. why are you beating a dead horse?

Thanks for all the help.
I used this in the end:

Step 1:
turn the vob into mp4

ffmpeg -i VTS_01_4.vob -c:v libx264 -c:a aac -strict experimental VTS_01_4.mp4

Step 2:
Create a text file and include the paths and names of each file to concatenate (or "join"). Example file,
input.txt:

file '/home/jenia/input1.mp4'
file '/home/jenia/input2.mp4'
file '/home/jenia/input3.mp4'

Step 3.
Now you can use the concat demuxer:


ffmpeg -f concat -i input.txt -codec copy output.mp4
