Hello Marcus, I understand what I can use in my project, but I have a problem. Can you inform me how I can give my real-time video(taken from camera) as input to the uhd_packet_tx_tun example. For example, when I use a 'file source' block at the input, it says that "No connection known between domains stream and message." How can I do the necessary transformations? Or which input block is better to use here? Thanks for the help. Regards.
