rsonvif: How to use onvifmetadataoverlay?
We are going to stream video and metadata (as bounding boxes and some other text information) from IP camera supporting ONVIF profile M. We would like to use rsonvif plugins. We are able to display video and display/save metadata as XML (for example: gst-launch-1.0 rtspsrc location=rtsp://user:password@ip/rtsp/xxxx ! application/x-rtp, media=application ! rtponvifmetadatadepay ! filesink location=data.txt
). It looks that onvifmetadataoverlay
can display metadata on video but we don't know hoe to use it. Does anyone have some examples of working pipelines with onvifmetadataoverlay
?
