has_callback property

  1. @Int()
int has_callback
getter/setter pair

Specify whether the device supports callback. Devices that implement "active interface" will actively call the callbacks to give or ask for video frames. If the device doesn't support callback, application must actively request or give video frames from/to the device by using pjmedia_vid_dev_stream_get_frame()/pjmedia_vid_dev_stream_put_frame().

Implementation

@pj_bool_t()
external int has_callback;
