The h264 encoder is accessible through OpenMAX. This should be enough 
information to make use of it:
http://www.khronos.org/openmax/il/
https://github.com/raspberrypi/firmware/tree/master/documentation/ilcomponents
along with the decoder code in 
https://github.com/raspberrypi/firmware/tree/master/opt/vc/src/hello_pi/hello_video

p.s. App with GPU DEcoding - https://github.com/wrightrocket/omxplayer
