the O.S. is Linux. I have an old c++ code that writes raw SDI input from a capture device to a file. My intent is to modify this program and redirect the raw video from the SDI source to the stdin of ffmpeg. How can I do that? Is better to run ffmpeg within the c++ source code (how can I do that?)? Thank you very much.

Open a pipe, start mencoder and configure it to read from the pipe. Then write data to the pipe.
If you want to use a library, write a code (etc), then take a look into libav

libavcodec has long since been renamed to libav, and is the core library of the ffmpeg project. – greyfade Apr 14 '11 at 15:44

@greyfade: I think libav is a recent fork. You have both libav.org and ffmpeg.org now :) – neuro Apr 14 '11 at 16:35

I can not use library because I have to use an old version of ffmpeg that support vhook. So I will try a pipe, hoping that ffmpeg is able to recognise the data that I put it inside. – cicvsalba Apr 15 '11 at 07:38
