  1. hi !
    I have vob files with multiple audio inside.
    I would like to extract all the audio streams from all the vob files automatically.

    I have tried this :

    for %%a in ("*.vob") do ffmpeg -i %%a -vn -acodec copy %%~na.ac3

    but this will extract only one ac3 track from each vob.
    So how to batch extract all ac3 streams included in vob files please?

    I guess you have to use the map command.

    Or maybe try pgcdemux,
    Code:
    Command line support
    PgcDemux [option1] [option2] ... [option12] <ifo_input_file> <destination_folder>
    option1: [-pgc, <pgcnumber>].      Selects the PGC number (from 1 to nPGCs). Default 1
    option2: [-ang, <angnumber>].      Selects the Angle number (from 1 to n). Default 1
    option3: [-vid, <vobid>].          Selects the Angle number (from 1 to n). Default 1
    option4: [-cid, <vobid> <cellid>]. Selects a cell vobid (from 1 to n). Default 1
    option5: {-m2v, -nom2v}. Extracts/No extracts video file. Default NO
    option6: {-aud, -noaud}. Extracts/No extracts audio streams. Default YES
    option7: {-sub, -nosub}. Extracts/No extracts subs streams. Default YES
    option8: {-vob, -novob}. Generates a single PGC VOB. Default NO
    option9: {-customvob <flags>}. Generates a custom VOB file. Flags:
               b: split VOB: one file per vob_id
    		   n: write nav packs
    		   v: write video packs
    		   a: write audio packs
    		   s: write subs packs
    		   i: only first Iframe
    		   l: patch LBA number
    option10:{-cellt, -nocellt}. Generates a Celltimes.txt file. Only in PGC/VID mode. Default YES
    option11:{-log, -nolog}. Generates a log file. Default YES
    option12:{-menu, -title}. Domain. Default Title (except if filename is VIDEO_TS.IFO)

    Or ReJig. It also has an option to fix the audio delay.
