Failed to receive SDP offer from WHIP sink: SDP offer not found

onorua commented 5 months ago

I've tried to follow instructions:

run docker container to stream SRT: docker run --rm -p 1234:1234/udp eyevinntechnology/testsrc
run srt_whep: srt-whep -i 127.0.0.1:1234 -o 127.0.0.1:8888 -p 8000 -s caller | bunyan
Tried checking SRT stream with: gst-launch-1.0 playbin uri="srt://127.0.0.1:8888"
Got sound and video from docker
Put http://localhost:8000/channel in URL field at https://webrtc.player.eyevinn.technology/
Pressed play and got SDP offer not found error in browser and terminal consoles.

Chrome:

WHEPAdapter.ts:314 WebRTC-player server does not support client-offer, need to reconnect

Expected result: WebRTC in WHEP mode is working and I see the same stream as I can see with gst-launch-1.0 playbin uri="srt://127.0.0.1:8888" inside the https://webrtc.player.eyevinn.technology/ player.

Hi @onorua, Thanks for trying it out.

(srt-whep:969624): webrtcsink-WARNING **: 19:52:37.526: The rtpgccbwe element is not available not doing any congestion control: BoolError { message: "Failed to find element factory with name 'rtpgccbwe' for creating element" }

From the log you shared, it seems that some elements from GStreamer are missing. Most likely we had some problems installing the framework. But it should be easy to fix. I wonder if you are building it from the source or installing from Cargo? And what platform (MacOS or Linux) are you expecting to run it?

If you are building from the source code. Maybe you have installed GStreamer packages and would you like to check with the command gst-inspect-1.0 rtpgccbwe? In my case, the outcome looks like the following.

Factory Details: Rank none (0) Long-name Google Congestion Control bandwidth estimator Klass Network/WebRTC/RTP/Filter Description Estimates current network bandwidth using the Google Congestion Control algorithm notifying about it through the 'bitrate' property Author Thibault Saunier tsaunier@igalia.com Documentation https://gstreamer.freedesktop.org/documentation/rsrtp/rtpgccbwe.html ...

Some more details about your running environment would help a lot to fix the problem.

Docker environment worked out fine. So I've checked the list of packages suggested in the installation guide and looks like these 3 were not installed: gstreamer1.0-gtk3 gstreamer1.0-nice gstreamer1.0-qt After installing - I see the test stream. Sorry for bothering!
