Audio from VOB?

DataCable · 9th August 2003, 15:13

Is there currently a method of reading an audio stream directly from a VOB, without the need to decode/demux it out first? I found this thread, in which Nic offered to add direct VOB support to Marc FD's ac3Source, but that's the only reference to such I could find.

Hi and welcome. I don't believe there is any method. The only program right now I know of that can read audio direct from VOB's is BeSweet along with DVD2SVCD's vobinput.dll. You could, however, Use nic's call plugin along with besweet to do it in an avisynth script. Something like:

LoadPlugin("call.dll")
Call("Besweet.exe -core ( -input 'whatever.lst' -substream 0x80 -output 'whatever.wav -2ch) -azid ( ... )", "-2" )
audio=Wavsource(whatever.wav)
video=MPEG2Source().# your other commands and filters here
AudioDub(video, audio)

Then run the script through your encoder of choice, inserting paths as necessary, where whatever.lst lists the .vob's, this example would be for wav audio, and using the "-2" at the end of the command would start the besweet encoding before any video is encoded. hth,
