Will it be possible to get access to the Video or Audio Stream Data before it is sent out?
To give some background information on why I am asking: I would like to add command messages to the video stream to send from one device to another. To do that I want to discard a small part of the actual frame and replace it with my command message structure before sending it out. On the receiving end, the command message would then have to be separated from the video frame before displaying it. Alternatively I could also use the audio stream for the command messages, as I won't be needing audio for my application.
In the current SDK neither option is available as the publisher takes the video data directly from the surface view and sends it out while the subscriber puts the received stream directly in the surface view to display the video.
