Why do I only see black frames on sending my custom render target through NDI sender media?
Although not specifically addressed in the examples and documentation, the plugin was designed to allow users to send their own video over NDI without using the NDI Broadcast Actor. When creating your Render Target, the size of the Render Target must match the size of the sender frame size. Also, you must ensure that the Render Target Format is set to “RTF RGBA8”.
