Hello, When the built-in camera is not instantiated a crash occur at: IMediaFilter_Stop(stream->dgraph.media_filter); because the pointer is null. I have change the code to: if (stream->dgraph.media_filter) ????? IMediaFilter_Stop(stream->dgraph.media_filter); and this solve the crash. I still have the problem of not able to render/filter the camera. The error messages are: 22:28:51.500??? pjsua_vid.c? .......Setting up TX.. 22:28:51.500??? pjsua_vid.c? ........Creating video window: type=preview, cap_id=0, rend_id=2 22:31:50.796???? vid_port.c? .........Opening device Integrated Webcam [dshow] for capture: format=YUY2, size=352x288 @30000:1001 fps 22:32:36.937??? dshow_dev.c? .........Error creating filter graph: CoInitialize has not been called.?
