[Live-devel] No data from the VND.ONVIF.METADATA subsession

[Michael McCandless]

I'm using testRTSPClient to pull an RTSP stream, and I noticed the
camera provides two subsessions:

  [URL:"..."]: Initiated the "video/H264" subsession (client ports
56266-56267)
  [URL:"..."]: Set up the "video/H264" subsession (client ports 56266-56267)
  [URL:"..."]: Created a data sink for the "video/H264" subsession
  [URL:"..."]: Initiated the "application/VND.ONVIF.METADATA" subsession
(client ports 49032-49033)
  [URL:"..."]: Set up the "application/VND.ONVIF.METADATA" subsession
(client ports 49032-49033)
  [URL:"..."]: Created a data sink for the "application/VND.ONVIF.METADATA"
subsession
  [URL:"..."]: Started playing session...

And then I proceed to get many frames, but only for the video/H264
subsession.  I never see any data sent to the afterGettingFrame for
the application/VND.ONVIF.METADATA subsession ... is this expected?

I thought this subsession might provide details from the camera like
maybe motion detection events or something (just a guess)...

Or is there something different I need to do to "start" the metadata
stream?

Thanks!

Mike
