Hi - first time for me to post here...
I have been using transcode for about a year to (amongst many other
things) encode backups of DVDs to xvid for use on a portable hardware
player. This works very well, but with the following snag: when I rip
the dvd in chapter mode (using the -U flag), many of the individual avi
files don't start with a key frame. This causes either the hardware
player (or playback software like mplayer) to show a broken picture
until the first key frame is found.
I use the following shell script to do two pass encoding. Have I
forgotten something?
RATE=700
for PASS in 1 2
do
transcode -i /dev/hdc -U movie_700_$PASS -R $PASS -V -x dvd -y
xvid -w $RATE -Z 720 -J dnr
done
I find that I can re-rip the chapters which are broken using the -T1,n
option (where n is the chapter number) and this does produce files which
have an opening keyframe, although this is sometimes itself slightly
broken (has empty blocks).
Any ideas?
