Hi! Why pjsua_call_set_vid_strm with PJSUA_CALL_VID_STRM_CHANGE_DIR doesn't use cap_dev from pjsua_call_vid_strm_op_param? In my case i have decoding video stream and i'm going to add encoding direction. Is any other opportunity to override default capture device for a call before starting encoding stream? PJSUA_CALL_VID_STRM_ADD works fine, but it only works when call has no video media.
