    initial v2  
    1 This can be useful in situations where video camera access is exclusive, so we delay opening the video capture until it's really needed.

     3This ticket will include: 
     4- Avoid creating the video capture if the setting vid_out_auto_transmit is false 
     5- Decrease the video capture reference count when the outgoing transmission is disabled (via the API pjsua_call_set_vid_strm() with op PJSUA_CALL_VID_STRM_STOP_TRANSMIT). When the reference count reaches zero (i.e. no other calls nor the preview window is using it), then the video capture will be released.
