I would prefer that this stream be decoded inside of the channel driver.  Then,
the audio and video should be sent into the core as AST_FRAME_VOICE and
AST_FRAME_VIDEO.  The control data should also be handled inside of the channel
driver, with some of the information passed into Asterisk using
AST_FRAME_CONTROL as appropriate.  This is how every channel driver works.
