pyvnc2swf not working? outputs video of duration 0sec

i need to convert video from swf to flv. im开发者_JAVA百科 using pyvnc2swf : edit.py but it's not working. shows no errors but outputs a file with one blank frame.

here is the command:

/usr/share/pyvnc2swf/edit.py -o outlet.flv -s 1 1.swf

output:

Using pygame 1.9.1release there is no soundcard Input movie: version=7, size=718x351, framerate=24fps, frames=1, duration=0.0s. Output movie size: 718x351 Scanning source swf file: 1.swf... .1 frames written (duration=0.0s)

i got the answer on my own : pyvnc2swf is working perfectly but it won't work with the swf's which are interative(require clicking etc). u can only convert simple swf's to flv.
