I originally posted http://www.raspberrypi.org/phpBB3/viewt ... =40659&e=0 in the C++ forum before I realized this subforum existed.

(Happy to relocate my original thread... or it'd be great if the moderator could do that for me!)

If it was me, I'd feed it to the input of the H.264 encoder, rather than the image encoder. I believe that if you set the input port characteristics correctly it'll take a stream of images -- it'll happily eat the output of the resize and image_fx components; see omxtx in this forum for details -- and you'll end up with a nice video stream instead of MJPEG. I'd then drop the timecode into the metadata (MPEG TS TDT / TOT given the choice, but that's not going to be to everyone's taste), rather than in-vision.

I'm also underwhelmed at the utility of libilclient. I had more luck ignoring it and using the OpenMAX spec. and interfaces raw. OpenMAX isn't pretty -- my list of complaints with it can probably be found quite easily -- but I have to admit it does mostly work.

Just a couple of thoughts.

Good luck...
