App Crashing
I followed your code, when I add this line
rtmpUSB.startPreview(mUVCCamera,UVCCamera.DEFAULT_PREVIEW_WIDTH,UVCCamera.DEFAULT_PREVIEW_HEIGHT);
in the connect function it is crashing. Without this line there is no crash, is it possible for you to help

Sorry, this project is abandoned because I have no way to test it (I don't have UVC camera anymore). I can't help you with this.
