[FFmpeg-devel] How to watermark video using ffmpeg?

[PHP Freak]

Hi, I have been trying to use ffmpeg to watermark videos but I couldn't. I can't even find vhooks for ffmpeg or get able to find old source to re-compile it, I get to know that vhook is renamed to LibAVFilter but I cant find any example to use it to watermark any video so finally posting here after tired of searching for 3 days. hope someone wil help me out :-)

Thanks
