[MEncoder-users] Mencoder SIMPLY Freezes or gives a mpg123: Can't rewind stream by 20 bits! error

[Lucas Linard]

When I run the following command, mencoder starts ok, but at some
point during 1st pass, it just freezes. It won't accept any command,
no ctrl+c or something. ust there's no way (that I know) to get it
working again.
It happens always at specific point of the video (it changes as I
change the video file).
The command is this:

mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf -vf
crop=704:400,scale=720:400,expand=720:576,harddup -srate 48000 -af
lavcresample=48000 -lavcopts
mbd=2:trell:last_pred=2:dia=-1:vmax_b_frames=2:vb_strategy=1:cmp=3:subcmp=3:precmp=0:vqcomp=0.6:vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=1800:keyint=15:vstrict=0:acodec=ac3:abitrate=192:aspect=4/3:border_mask=0.3:vpass=1:turbo
-o "/dev/null" "movie003.mp4"

mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf -vf
crop=704:400,scale=720:480,expand=720:576,harddup -srate 48000 -af
lavcresample=48000 -lavcopts
mbd=2:trell:last_pred=2:dia=-1:vmax_b_frames=2:vb_strategy=1:cmp=3:subcmp=3:precmp=0:vqcomp=0.6:vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=1800:keyint=15:vstrict=0:acodec=ac3:abitrate=192:aspect=4/3:border_mask=0.3:vpass=2
-o "movie_converted_03.mpg" "movie003.mp4"

Also with some videos I get this error:
"Skipping frame!

I use mencoder from Ubuntu Feisty repos.
