Hi,

I use the ffmpeg.exe(size 6.5mb) to convert videos to FLV. I'm developing a web application using asp.net .

Chances are that your ffmpeg.exe won't have compiled vhook support. Just compile yourself one that has.

I would like to get some help using this ffmpeg to create watermarks and attach it to the FLV videos.

I hope u can guide me or help me....

Start here: http://ffmpeg.mplayerhq.hu/documentation.html and read at least the "video hook documentation" and the "FFmpeg Windows Help" Regards, V?ctor
