I have a drone. I am able to streaming camera live video from drone to phone with dji sdk. I want to use wikitude on this camera view. How can I do that ? How can I change wikitude's camera source ? How can I set wikitude's camera source to my virtual camera ?
yes, that's exactly what you would need to implement. If you look at the YUVFrameInputPlugin.cpp file, you'll notice that it actually does receive its character data from Java through JNI; so it is actually very close to what you would ned to do in your plugin.
I found YUVFrameInputPlugin.cpp. Do you mean I need to write this C++ Plugin to get the raw video data from the dji sdk and pass to the wikitude sdk? The dji's Video Stream Decoding is JAVA code. Could they integrate together?
that is indeed possible. What you need is a feature we call the input plugins API. You can find the corresponding documentation page here.
