gstvaapi and refused connection error rtspclientsink

[larry_b_84]

Hi

I am trying to do something relatively simple - I hope.

I am running on a raspberry pi and using the latest version of gstreamer.

My initial task I was trying to do was to create an RTSP 'repeater' using
gst-launch-1.0 rtspsrc rtspsrc location=rtsp://192.168.0.102:5540/ch0 !
rtspclientsink location=rtsp://127.0.0.1: 8554/test .

However I keep getting the error message:

ERROR: from element
/GstPipeline:pipeline0/GstRTSPClientSink:rtspclientsink0: Could not open
resource for reading and writing.

(Any comments on the above pipeline would be appreciated.)

So I have tried to change the pipeline to something that I know should work.
However I appear to have two issues gstvaapi wont work for obvious reasons
(arm processor) and secondly I'm getting a connection refused error. I have
pasted the error below.

Many thanks

Laurence

Be aware that rtspclientsink is means to connect to a remote server that
implements the RECORD function. Just saying, as if you want an RTSP proxy,
you'll need to use rtsp-server library and create a server.

As rtspsrc is multi-pads (in some cases you may need to redo the payload), this
is quite more work and you will need to program this. For each pads, you will
have to create an equivalent pad on rtspclientsink and connect it.

You don't seem to have any server running that would implement RECORD, so I
suppose that you miss-interpreted what rtspclientsink is.

As you have a very specific task, have you consider using a generic RTSP proxy
server, like Live555 proxy server or other RTSP proxy application ?
