Problem streaming with OBS

[parwan42]

Hello,

I have set up Janus with the Simple-Whip-Server (SWS), SWS has successfully connected via WebSocket. I created a whip endpoint tester-1 with a token. OBS is configured to https://api.janus.nomadenflotte.de/whip/endpoint/tester-1 with token.

When I'm starting the stream, I get this error log:

[WARN] Video offered as 'sendonly', but we need 'inactive' for us: using 'inactive' [ERR] [sdp-utils.c:janus_sdp_get_codec_pt_full:780] Unsupported codec 'none' [WARN] Couldn't find codec we needed (none) in the offer, rejecting video [WARN] [1532021703840573] ICE failed for component 1 in stream 1, but let's give it some time...

You're probably trying to publish to a room that doesn't support H.264 (which is the codec OBS will use).

[parwan42]

Thanks for the super-quick response, Lorenzo!

[1234] description = Demo Room secret = publishers = 6 bitrate = 128000 fir_freq = 10 audiocodec = opus videocodec = h264 record = false ;rec_dir = /tmp/janus-videoroom

I tried h264, x264, H264

Make sure you restart Janus when you modify configuration files.

[parwan42]

sure, I run docker compose down && docker compose up -d after this I restart SWS and recreate the endpoint

Are all versions of Janus supporting WHIP? There is a 0.12.x release branch and a 1.x branch?

Could that be the issue?

Hi Lorenzo,

I finally got the server running with the VideoRoom demo. None of the Docker files linked around here did the trick, below is the configuration that I got working.

Now I have a persistent issue where if more than one stream connects to the server, the connection becomes unstable and streams are disconnected and reconnected all the time.

[lminiero]

I'm sorry but this repo is not for handling Janus usabilty issues, including configuration, deployment and management. I'd rather keep issues here only around the management of WHIP signalling. If using the Janus demos directly, without the WHIP part, gives you the same problems, you may want to refer to the Janus community group for more help on Janus itself.
