[MPlayer-users] encoding problems after upgrade to 1.0-pre3

Thu Dec 25 16:19:33 CET 2003

i was using 0.90 for some time, and recently upgraded to 1.0-pre3. this seems 
to have had a crippling effect on encoding. i understand very little about 
video, or about the different mencoder options, but after going through the 
list archives at some length, it seemed to me that this was a good 
commandline for two-pass encoding from vob files:

mencoder -sws 2 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=800:vhq:v4mv:trell:\
precmp=3:cmp=3:subcmp=3:vmax_b_frames=1:qpel:vlelim=-2:vcelim=7:\
lumi_mask=0.05:dark_mask=0.05:naq:vqcomp=0.7:mbcmp=2:psnr:vpass=x\
-oac mp3lame -lameopts q=0:aq=0 -vop crop=700:372:8:104 -o castaway.avi\ 
castaway.vob

sorry about the wrapping lines.

for some movies, i need to add -ofps 23.976, or the resulting video is jerky, 
because of something called telecine which i don't really understand. i'm 
doing most of this parrot-fashion, without really understanding what does 
what, because i'm quite ignorant about video.

now the above commandline used to work pretty well in 0.90, but it has stopped 
working after the upgrade. stopped working in any useful way, that is. the 
first pass goes through, but gives almost no compression. castaway.vob was 
5.2 gigs, the resulting castaway.avi was 4.8 gigs. antz.vob was 2.3 gigs, 
antz.avi 2.1 gigs. this was not the case in 0.90.

the second pass refuses to get going. it takes a few seconds to read the log 
files from pass 1, then exits with a segmentation fault. the exact output 
(with -v) is attached herewith.

someone please take a look and tell me what's wrong.

my system is SuSE 9.0 on athlon 2100+ xp, Asus A7V8X mobo (Via KT-400 
chipset), built-in sound, NVidia Geforce 3 Ti 200 AGP card, 256 megs of ddr 
ram @ 333 mhz (running at 266 really).
