Transmitting video from one USRP to another is possible, but we don't right now have an example showing how to do it.
One approach to doing so would be to partition the problem up into sections that can be addressed somewhat independently. For instance, you know that the video stream boils down to a stream of bits, with this in mind, you might start from the packet-based link demo (https://decibel.ni.com/content/docs/DOC-18801) modifying the message source (on the transmit side) from what it is currently to a stream of bits representing video. You would also modify the receiver side code so that the incoming stream of bits would be handled as video.
The essential task is to convert a video stream to/from bits.
