After fumbling with options I came up with a command line that seems to almost
work; however, the last and seemingly(?) crucial option I added, "-A", produces
the fatal error " critical: Oops, this version of transcode only supports PCM
data for audio transformation"
That led me to search for a way to rebuild my (1.0.6) transcode with AC3
support enabled but i didn't find any clues in documentation.
Bottom line here: how do I transcode VOB's to AVI's, with AC3 audio fully
preserved, with as many channels as i start out with?
I found a wiki saying that transcode automatically mixes 3 or more audio
channels down to stereo (2 channels). But what if i don't want this?
I know there is a way to preserve 5.1 or whatever, when transcoding VOB to
avi's (ffmpeg) -- (handbrake does it, for example)
Below is my commandline.
With the "-A" option ommitted from it, transcode proceeds and finishes (save
for the glibc problem addressed earlier, as well as a couple of other issues
like wrong aspect, which i'll address in a separate post)
