[MEncoder-users] accuracy of -ss -endpos function

[belcampo]

Hi all,

I'm using the -ss -endpos function but results in a/v sync problem, the 
v-part got bigger after putting the parts together.

What I did
mencoder sourcefile -nosound -noskip -mc 0 -ovc x264  -x264encopts ..... 
-of rawvideo -o destination.h264

results in Duration 00:28:56.960

mencoder sourcefile -nosound -noskip -mc 0 -ovc x264  -x264encopts ..... 
-of rawvideo -o part0.h264 -endpos 350
mencoder sourcefile -nosound -noskip -mc 0 -ovc x264  -x264encopts ..... 
-of rawvideo -o part1.h264 -ss 350 endpos 350
mencoder sourcefile -nosound -noskip -mc 0 -ovc x264  -x264encopts ..... 
-of rawvideo -o part2.h264 -ss 700 endpos 350
mencoder sourcefile -nosound -noskip -mc 0 -ovc x264  -x264encopts ..... 
-of rawvideo -o part3.h264 -ss 1050 endpos 350
mencoder sourcefile -nosound -noskip -mc 0 -ovc x264  -x264encopts ..... 
-of rawvideo -o part4.h264 -ss 1400 endpos 350
cat part0.h264 part1.h264 part2.h264 part3.h264 part4.h264 > part01234.h264
results in Duration 00:29:07.520
