Hello,
I wrote about this problem some days ago, but after several tries (and
ditto useless burned dvd's...), I still have the same problem. So I'll
post a more detailed description of the process. I'd be very happy if
you could give it a look, and see if the error is obvious. In any case,
the information might be usefull for other people anyway.
The problem in short: I burn 8 mpegs, converted from minidv, to dvd. All
work, except the one in which I added a 6 second intro (made with one of
the first frames repeated). I've done this used kino (simply copying the
frame several times), and now I use png2yuv (because I editted the image
a little bit with the Gimp). The mpeg starts playing, but the time
counter (on the standalone player) stays at 1 second, and once the real
part of the mpeg (after the created intro) starts, it plays only about 1
second, and then it skips back to the beginning. If I search to 7 seconds,
it continues playing correctly.
====================================================================
#
# Grab the dv video, resulting files: dvgrab-001.avi dvgrab-002.avi , etc
# This process is the same for all eight tracks.
#
dvgrab --autosplit
#
# The custom step for the track-with-intro.
# Generate the intro, as dvgrab-000.avi , so it will be encoded before
# the dvgrabbed avis. (nb: not 100% sure about the lav2wav/lavaddwav
# settings, writing this from the top of my head)
#
png2yuv -n 150 -f 25 -I b -L 1 -j intro.png | yuv2lav -o tmp.avi
lav2wav -r 48000,16,2 > tmp.wav
lavaddwav tmp.avi tmp.wav dvgrab-000.avi
#
# convert to mpeg, based on florin andrei's howto
# (same for all eight tracks, but in case of the track-with-intro, it
# will include the generated dvgrab-000.avi)
#
bitr="8500"
flags="-c -q 6 -4 2 -2 1 -K file=matrix.txt -R 2"
lav2yuv dvgrab-*.avi mpeg2enc -f 8 -a 2 ${flags} -n p -b $bitr -o out.m2v
lav2wav dvgrab-*.avi | mp2enc -r 48000 -b 224 -s -o out.mp2
mplex -r 9800 -f 8 out.m2v out.mp2 -o out.mpg

# create menu with spumux, and after running dvdauthor, burn the image
#
growisofs -dvd-compat -speed=2 -Z /dev/scd0 -dvd-video /data3/dvd
====================================================================
(at some point, I managed to create two DVD's that _did_ work, but
then I lost my history... so I am not sure if that has been luck, or
some change in the used settings...)
Thanks in advance!
Maarten
