Re: Janus Videoroom Conference Not displaying Stream

[Lorenzo Miniero]

When you don't get valid streams, you're much better off looking at the Admin API instead:

Hello Lorenzo, this is in regard to the questions I emailed you about with UV4L, Janus and IP Cam. Attached is a log that would give complete descriptions of all the message logs when I try to join a video conference and see no stream displayed.
Thank you!

[Lorenzo Miniero]

Not sure what you're using, but that's not the Janus API... possibly the UV4L one?

(PS: please don't paste huge logs or dumps inline, we use pastebin/gist for that to keep threads small and readable)

Hello Lorenzo thanks for your Reply,

I did some further debugging tests with the admin API and a RESTFUL API as well, and I realized the issue I am having is that with the Video Room Plugin and Events, I am getting error code 404 Access Denied or Page Not Found, do you think its a setting with registering a username in the room? I have not configured the pin for a room. Also could it be related to port blocking issues outside of Janus? Posted below are the excerpts of the Restful API tests for you to please direct me if the issue is outside of Janus or a setting I did not add or maybe rights of users. My /opt/janus directory is owned by "root" so it my Apache Webserver. But I am running Janus as a different user under ubuntu VM.

LoL Thanks! Yes, I know well not to paste huge lines of code, but I thought for simplicity sake to just post a few excepts from what I had. The issue is the Access denied in the video room now. The Admin logs was not different from my initial first log attachment, I don't know if you took a look at it.

Inline code AGAIN? Seriously? After I just asked you please not to do that?

The syntax for admin api requests is in the documentation page you already found. More precisely, handle_info is what you're looking for.

According to one of your past posts you had said "As for the Janus API, the Admin API also always expects a POST with a payload:

https://janus.conf.meetecho.com/docs/admin"

How do I send a POST with a Payload please?

did you create the videoroom plugin resource with the UV4L rest api after having created the session? it seems you did not

Ok, so you are using the Janus DEMO page on the UV4L server, which does NOT use/has *nothing* to do with the UV4L RESTful API (using the latter while using the former is just unsupported) . Forget what I said then.

Thanks for your Reply Webmaster, the only way I tried to join the Janus Video room was through the URL from the UV4L web page, it has an option to create or Join Janus Video Room, Once I put in all the credentials on that page when it opens up the Janus Gateway configurations and I press "Start" from the UV4L web page it greys out and the stream logs is all I have been posting. It seems for some reason not to do anything besides greying out after pressing start. In the Janus logs as well it shows opening UV4L channel after starting the stream. If Lorenzo tells me my "handle_log file" from the Janus admin web page is fine, then the only thing I can suspect would be my local machine because my mic port is disabled from giving output. Maybe this might be the cause. I am also willing to share my solutions with your users if interested for the IP CAM version of Janus and UV4L once fully working.
Thanks!

Just in case anyone might want to try this implementation there are are few things to take into account when configuring the described setup on a Local server, the most important being able to set up a proxy for Janus for the front end web-server (Apache or ngix) and configure the HTML scripts if you choose to use the demos for Janus(i.e streaming.html, text-room, Video-room etc), its also important to note that if you didn't install a renderer for UV4L, the web page demo for UV4L only publishes the stream but you would have to create a canvas to view the stream or use one of the available demo rooms on a web browser(google-chrome or chromium in my instance) as described above.
