Problem with whipwebrtcsink uplink to Dolby.io, was Problem with NDISRC, WHIPSINK, and audio

Mon Aug 7 18:26:56 UTC 2023

Hello Tarun

I have rebuilt gstreamer and tested again with Dolby.io <http://dolby.io/>

This its failing on a different tack.

gst-launch-1.0  ndisrc ndi-name="PRIMARY (SIGGEN)" ! ndisrcdemux  name=demux demux.video ! queue ! videoconvert ! whipwebrtcsink name=ws signaller::whip-endpoint="https://director.millicast.com/api/whip/myStreamName",auth-token='..redacted..' demux.audio ! queue ! audioconvert ! ws. 

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Redistribute latency...
Redistribute latency...
Redistribute latency...
ERROR: from element /GstPipeline:pipeline0/GstWhipWebRTCSink:ws: GStreamer encountered a general stream error.
Additional debug info:
net/webrtc/src/webrtcsink/imp.rs(1499): gstrswebrtc::webrtcsink::imp::BaseWebRTCSink::connect_signaller::{{closure}}::{{closure}} (): /GstPipeline:pipeline0/GstWhipWebRTCSink:ws:
Signalling error: Error: Unexpected response: 401 - Unauthorized
Execution ended after 0:00:02.364739232
Setting pipeline to NULL ...
Freeing pipeline ...

I have confirmed the same authentication token works fine with the older whipsink method, so if authentication is failing, it's not simply due to a bad token. 

Please let me know your thoughts ?   

Are you able to test with dolby.io <http://dolby.io/> ?  they have a free account mechanism for this sort of testing.

Many thanks for your help.
