New Post: watermark video mp4/mov/avi

hello

i use your code example, for watermark a video,
as in this link ,that you published: code_sample2.html

but it works only for .wmv videos.
(for other types of videos i get an exception or it run without ending)

how can i make it work for mp4 or mov or avi videos, also?
what i need to change in the code?

thanks :)
