Gstreamer might be an option. It is a C stack, and it is used for a similar purpose (I think) on embedded hardware, ie TI's davinci processor.

I don't know to which extent it is effectively used or useable on such hardware. However, Gstreamer effectively has all the component needed for video and audio muxing and streaming.

Since it is a pipelined / modular approch, you can plug into gstreamer at any stage, ie keep the video acquisition / compression as custom code, and only use the RTP side of your app to gstreamer.Or you can write a custom compression plugin, and use "standard" gstreamer apps with your custom hardware accelerated hardware.
