[MPlayer-users] problems with NTSC

[Dominik Szczerba]

Hi,

I ma considering switching from Transcode to MPlayer (MEncoder, to be 
strict). I am trying to mencode NTSC vobs:

cat *.vob | nice -n 19 mencoder -oac mp3lame -lameopts cbr:br=128:q=2 
-ovc frameno -o frameno.avi -noskip -ofps 25 -
cat *.vob | nice -n 19 mencoder -oac copy -ovc divx4 -divx4opts br=1600 
-vop scale=640:360,crop=698:476:12:2 -sws 2 -noskip -ofps 25 -pass 1 -o 
movie.avi -
cat *.vob | nice -n 19 mencoder -oac copy -ovc divx4 -divx4opts br=1600 
-vop scale=640:360,crop=698:476:12:2 -sws 2 -noskip -ofps 25 -pass 2 -o 
movie.avi -

I am having the following problems:
1) video file is not in agreement with what I calculate (it's much smaller)
2) audio is not synchronized.

'Mplayer -v' says my vobs are 29.something fps. I tried without -ofps 
option as well. I didnt try without -noskip yet, but I believe that 
leaving out some frames results in slightly shaky video. Or am I wrong?
My version is MPlayer 0.90pre6-2.95.3. I havent found in CHANGELOG 
anything that seemed a good reason for an update. Or am I wrong?

Transcode has the same problems, no matter what options I choose.

I would do more debugging but MPlayer lacks a very usefull option 
-startpos, counterpart of -endpos, which makes it impossible to test 
critical parts of DVD.

I tried browsing mail archives, but my modem connection is too slow to 
browse thru everything, and what I found was not conclusioned.

would you please advice?
thanks
