awskvswebrtcsink: Gstreamer encountered a general stream error.

[Alec Gurman]

Hi,

I am attempting to get awskvswebrtcsink working on a Jetson Xavier NX,
Ubuntu 18.04.4, JP4.4, DS5.0. I have custom built GStreamer 1.20.6 and
built gst-plugins-rs/net/webrtc with Cargo 1.68.2. I am using the default
1.14 compiled L4T and DS gstreamer plugins which seem to be working fine
for my other pipelines. My current pipeline (which is constructed via
gst-python) looks like the following:

RTSP Camera/s -> uridecodebin -> nvstreammux -> nvstreamdemux ->
nvvideoconvert -> capsfilter  (video/x-raw(memory:NVMM),format=I420) ->
awskvswebrtcsink

I have a similar pipeline working well with kvssink, however when trying
awskvswebrtcsink, I am not getting any output.  Codec pipeline discovery
seems to work for H264 / H265 / VP9, though shortly after discovery the
below logs appear (with GST_DEBUG=4):

GST_EVENT gstevent.c:892:gst_event_new_caps: creating caps event

GST_ERROR_SYSTEM
gstelement.c:2301:gst_element_message_full_with_details:<webrtc-sink--0>
posted error message: GStreamer encountered a general stream error.

Anyone know how I can debug this further, or if this has been seen before?
