I didn't know about vhook but as I searched the web, i found it's been deprecated and replaced : libavfilter is the substitute for vhook which allows the video/audio to be modified or examined between the decoder and the encoder.

Why is that so that this module uses it, and is there any plan to implement libavfilter ?

libavfilter currently not in the official ffmpeg release. You need to get the google soc libavfilter from svn, and patch ffmpeg to support libavfilter. It is also difficult to configure correctly for example render a transparent watermark on a video.
But there are many posts about on the net, give a try.

Vhook was around when the module was originally written. I'd be glad to support libav if somebody wants to write up some code around that.

Thanks for your quick answers. There's not much I can do about that, I'm more a themer, but that's good to know.
