how to encode openGLES graphics as .h264?
just wondering if there is a simple solution before I start delving....

Re: how to encode as .h263?
[original question referred to h263]
Only h.264 encode is supported.
For GLES texture to h264 encode, you can do it now inefficiently (glReadPixels and submit these to openmax video_encode component).
It's probably not too bad - might do 720p30, but will keep the ARM quite busy.
Tim, a colleague who's been doing some work on getting camera data into textures using mmal, has been talking about providing a way to feed these textures directly into video encoder.
So, this may be possible more efficiently in the near future.

Dom,
that is excellent news indeed, could you provide or point to any simple code samples using:
"glReadPixels and submit these to openmax video_encode component"
Excuse my apparent ignorance, but any more information on Tim?
ie how to follow up on this lead, and receive any announcements?
