[GST-DEVEL]GStreamer RTSP Server use case

[Gottardi, Victor (ON19)]

Wes, I want two different URIs. For example:
  rtsp://ip-address:8554/high-res
  rtsp://ip-address:8554/low-res
For low bandwidth applications, the client would use the low-res stream.

I'm not sure if it's possible to select one stream if both are added to
the same URI as in:
  rtsp://ip-address:8554/both-res
Clients are typically not that smart. For example VLC would open an
extra window in this case (not implying that VLC is not smart, quite the
opposite).

Just being curious/dumb, do you have multiple endpoints (i.e.
Payloaders)
in your pipeline?  Something along the line of

     ... Complex-pipe ! tee name=t
       t. ! low-res-pipe ! rtpwxyzpay pt=100
       t. ! higfh-res-pipe ! rtpwxyzpay pt=101

So that the low and hires streams are sent out as different payload
types.
 Of course, this is going to be a single URI not two.  Did you want two
URIs?  I think the gstrtpbin in the receiver program ought to be able to
separate the payload type and gives you back two streams.

This idea is based on the rtsp example program test-video.c in the
/examples directory of the rtsp source package.

Of course I could be all wet.....
