[FATAL] [dtls.c:janus_dtls_load_keys:290] Error opening certificate file #1

Closed lc3t35 closed 5 years ago

Following your instructions, the docker for Janus fails to start with this error :

What's missing in the installation prerequisites or configuration steps ?

AminArria commented 5 years ago

Weird, seems to fail opening a certificate file. Some versions might not be pin down an mess the installation

I'll try a fresh install later tonight and see how it goes.

Let me know if you manage to fix it.

AminArria commented 5 years ago

@lc3t35 I've fixed it in latest commit ca0efac.

Seems like a change in Janus now causes the error when the cert config is present, but no cert is found.

PS: If error persist (or some other error) fill free to reopen/keep using this issue

Solved, thank you !

I can connect to the web page, following the given steps but there is no video displayed as broadcaster, where should be the video file ? maybe can you explain the html file in priv/static/janus-client ?

<video id="localVideo" autoplay muted style="width:40%;"></video>
<video id="remoteVideo" autoplay style="width:40%;"></video>
AminArria commented 5 years ago

What OS and browser are you using? The autoplay might cause some issues and you will probably have to allow the video recording, but it worked fine for me on macOS Firefox 69

Did it populate the room and feed fields?

lc3t35 commented 5 years ago

OSX and FF68. I can see the controls but no video. Which video is displayed, where is it stored ? Yes it populate the room and feed fields, no error in the console.

That's how it should display for a broadcaster. The video isn't stored anywhere, it's just as watching any other kind of video stream.

Did you try both options, janus-client and api-client?

lc3t35 commented 5 years ago

yep tried both, with Chrome too. It seems that the authorization to access the camera is not processed/given. I don't run at localhost but real server, maybe missing https can break the demo ?

AminArria commented 5 years ago

Ow... Outside of localhost I can't guarantee it will work. I'll try spinning up one later and see how it goes.

Nonetheless, since room and feed fields are populated connection to server seems to be working fine, so it looks to be a purely client-side specific issue. Try manually giving the permissions.

Also, if you don't mind, you could send me the IP/domain name of the server and I'll see if I can run the demo in my browser.
