Greetings all,
I'm trying to see what is the simplest way to grab video from screen, encode it
into h264 and save it to file, so I took the decode_encode.c (from
http://ffmpeg.org/doxygen/trunk/decoding__encoding_8c-source.html) and added a
grabbing part.

Greetings,
I'm writing a program that needs to capture an X session on linux.
as a design decision I've decided to split the grab and encode to two different
threads.
each input (e.g. video and audio) has it's own set of threads.

frame_size 8294400
looking at the code I see that unless stated else,
