Is there any known way to create transparent flv's, using ffmpeg?
I have lists of transparent png files that I am using to create videos, but the transparency is lost in the process:
ffmpeg -y -sameq -i %3d.png out.flv
I've been looking everywhere for a method to do that, and so far I have failed miserably.
The only tool that sort of comes close would be png2swf (which creates transparent swf files), but that comes with its own limitations, so flv files would be ideal.
