[Vnc2swf-users] Re: assertion error problem

[Yusuke S. <yu...@cs...>]

Bill,

This assertion error occurs when the flash file is not finished
properly. Usually this should never happen, because when you hit
Ctrl-C vnc2swf.py captures the signal and take a proper action to
close the movie. But when you hit a bad timing, it might end up in
the middle of something (probably image transfer/conversion
routine) and just jumps out from it without doing the job. I
experienced this a couple of times, and I think the probability
gets higher when you have a larger screen, because the duration of
this "critical section" gets longer.  And it is even higher when
you're using "Video" type encoding, because it is known to be
slower so you more likely will get a bad timing.

So, the answer I can propose is to use "shape" encoding instead of
"video" and convert it into "video" swf after recording.
