Hi all,
I have about a five and a half hour long concert I would like to burn as
audio on a DVD. I assumed that cdrdao or cdrecord would simply make an
"audio dvd" from the wav files, but that is not the case! My guess is
that there is something in the CDDA spec which prevents making an audio
CD over a certain length, because I get "illegal time code" errors from
cdrdao.
So, three questions:
1) Is there a way to master an "audio dvd" without encoding to a closed
DVD-A format? By this I mean a DVD disc with uncompressed audio which
can be played back by most CD/DVD combo players.
Hi;
Well, you could make a simple ordinary dvd video that (with luck)
would play in a stand alone unit, or in your computer. Something like:
(this is for NTSC, framerate different, the image size would be
different for PAL, and at least the '-n n' option should be '-n p'
in mpeg2enc)
Get a 720x480 jpeg image.
Turn image into couple second mpeg video:
# jpeg2yuv -n 100 -I p -f 29.97 -j my-pic.jpg | mpeg2enc -f8 -n n -o my-mpeg.m2v
Turn your giant audio blob into *raw* PCM 48000 sample rate, 2
channel, 16 bit, and apparantly *big endian*. (not a wav.) Name
it 'something.lpcm' The extention matters. An editor like
rezound, or sox, or ecasound can do this. (youll know if the
endian-ness wasnt right, it will sound like loud static)
Mux them together:
# mplex -f8 -L 48000:2:16 -o my-vid.mpg my-mpeg.m2v something.lpcm
(you can play the mpg at this point, but the player might stop after
the short video runs out...but, the sound should be there and a dvd player
should keep going.)
Make the dvd image:
(This is the dead simplest example; you can get much more fancy,
but Im not going into that now.)
# mkdir dvd
# dvdauthor -o dvd my-vid.mpg
# dvdauthor -T -o dvd
Test it:
xine dvd:/full/path/to/wherever/dvd/
(and I mean full path, and dont forget the trailing slash)
Burn it:
growisofs -dvd-compat -Z /dev/dvd -dvd-video dvd/
If you have problems or want to persue the question in another
forum, https://lists.sourceforge.net/lists/listinfo/dvdauthor-users
mailing list might be a good place.
