Inaccurate cuts with -ss

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]<

 



Hi all,

I'm trying to do something like this:
mencoder \
 $src             -ss 30 -endpos 1 \
 $src -vf hue=180 -ss 31 -endpos 1 \
 $src             -ss 32 -endpos 1 \
 $src -vf hue=180 -ss 33 -endpos 1 \
 $src             -ss 34 -endpos 1 \
 -o outfile.avi -oac pcm -ovc lavc -lavcopts vcodec=mjpeg

The output is not smooth but stutters at every cut point.  As I
understand it, -ss seeks to the nearest keyframe.  What would it take
to implement frame-accurate seeking so that a command like the above
would produce smooth output?
