Hi !
Today I tried to extract the audio track from a DVD, so I typed this
command in the console (my OS is Ubuntu 12.04 with a 3.13.0-44-generic
kernel) :
transcode -i /dev/sr0 -x null,dvd -y null,wav -T 1,1,1 -a 0 -E
44100,16,2 -m 01.wav
It's the 4th time that I run this command (with 4 different DVDs), but
this is first one where I encountered a problem :
[audio_trans.c] critical: Sorry, source audio format not supported
And the wav output blew my ears ! Besides that, I can read the DVD with
VLC, Totem and mplayer without any problem.
I looked for any similar issues on Google and on this mailing list but I
didn't find any. I just found the code that generates this error here :
http://fossies.org/linux/transcode/src/audio_trans.c and there :
http://fossies.org/dox/transcode-1.1.7/audio__trans_8c_source.html
Unfortunately I'm not a programmer so I don't understand very well what
is going wrong.
Anyway, if anyone is interested in this problem, I put the output of
transcode below. Thanks for your attention (and sorry for my bad english).
Best regards,
David
