Hey folks.
I've been using vobcopy and dvdbackup, and want to be able to extract the
multichannel audio. I have only been able to get 2 channel audio out at any
time. In fact, I recently ripped a dvd that I *know* has 5.1 a/52 stream on
it, and when I run tcprobe -i on the file, this is what is returned to me:
tcprobe -i ./DVD_VIDEO1.vob
[tcprobe] MPEG program stream (PS)
[tcprobe] summary for ./DVD_VIDEO1.vob, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
aspect ratio: 16:9 (*)
frame rate: -f 29.970 [25.000] frc=4 (*)
PTS=0.0610, frame_time=33 ms, bitrate=9800 kbps
audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x2000 [0x2000]

audio track: -a 1 [0] -e 48000,16,2 [48000,16,2] -n 0x10001 [0x2000]

PTS=0.0610, bitrate=192 kbps
-D 0 --av_fine_ms 0 (frames & ms) [0] [0]
I've tried extracting with the following combinations:
transcode -a 0 -x null,ac3 -y null,ogg -N 0xfffe -i ./DVD_VIDEO1.vob -o
./pinkfloyd.track1.ogg
transcode -a 0 -x null,ac3 -y null,mp2 -N 0x2000 -i ./DVD_VIDEO1.vob -o
./pinkfloyd.track1.mp2
I am currently running transcode 1.0.2 on Slamd64 (x86_64 unofficial
slackware) built with:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
--libdir=/usr/lib64 --enable-ogg --enable-vorbis --enable-libdv
--enable-mjpegtools --enable-gtk --enable-libiconv --enable-theora
--enable-libmpeg3 --enable-a52 --enable-freetype2 --disable-mmx
--enable-3dnow --disable-sse --enable-sse2 --disable-avifile
--disable-static --enable-libpostproc --enable-imagemagick
--with-a52-libs=/usr/lib64 --with-libpostproc-libs=/usr/lib64
--with-libpostproc-includes=/usr/include/postproc
--with-libavcodec-includes=/usr/include/ffmpeg
--with-libavcodec-libs=/usr/lib64
If anybody can assist and provide me with the information necessary to get
the 5.1 channel stream out, I'd appreciate it. I must be misunderstanding
something in the manpage.
Thanks in advance.
