ERR: Unsupported codec 'none' when using Videoroom plugin

[bugwheels94]

I am using videoroom plugin and when creating room. My RTCPeerConnection object often sends only either video stream or audio stream and I am not sure if that might be the case.

I send the configure request accordingly. My request to add RTCPeerConnection for only video looks like

{"body":{"request":"configure","audio":false,"video":true},"handle_id":6827022753202221,"janus":"message","jsep":offer,"session_id":4288389928036787,"transaction":"HJNFNzJvaM"}}

My Offer: http://jsbin.com/reyuxir/2/edit?html,output

The answer: http://jsbin.com/reyuxir/1/edit?html,output

And I get this error in Janus logs:

[ERR] [sdp-utils.c:janus_sdp_get_codec_rtpmap:718] Unsupported codec 'none'

May you please tell me some hint about the issue?

Regards

My request to create room if that matters:

        body: {

            request: "create",

            publishers: 100,

            bitrate: 10240000,

            videocodec: 'vp8',

            audiocodec: 'opus',

I'm seeing the same error after upgrading to 0.5.0

I'm publishing my video-only stream like so:

        const configure = {

          "request": "configure",
          "audio": false,
          "video": true,

        };
        publisher.handle.send({
          "message": configure,
          "jsep": jsep,
        });

Everything seems to set up OK, so it's unclear to me what's throwing this spurious error.

I tried digging through sdp-utils.c to understand the logic that throws it, but wasn't able to make sense of it.

Hey Chad,

I have also seen this error, but wasn't braking anything so left it alone ;)

I guess it is the audio: false that triggers it, actually the missing codec desc in m=audio, which should be missing anyway

Mirko,

I suspected as much. Seems that the videoroom plugin should be skipping that code if no audio is being sent, yes? The current situation is a false positive for an error condition.

[Mirko Brankovic]

If it is working, don't touch the code ;)

[Chad Phillips]

Is that a product salesperson or a developer talking? :P

I noticed it too, but since it's harmless I decided to focus on other priorities (and we had many). Anyway, in the unified-plan branch we're completely refactoring the internals and SDP management, so good chances are it will be dealt with there.
