no, there are no such things as timestamps in mencoder. that's why it
sucks. the frames will just be missing, so mencoder will duplicate the
previous frame over and over to make up for them.

ironically, what vj wants _can_ actually be done with audio filters.
if you make an audio filter that drops a huge segment of audio at the
same time as dropping the video, mencoder's bad a/v sync system will
kick in and should do the right thing.

but with mencoder's design, neither of these tasks should be performed
with filters...
