Details

Attempt to start an audio call at https://slack.com/.
No actual peers are necessary; not even calls to empty channels work.

With chromium 58.0.3029.110-1 it works,
with chromium 59.0.3071.86-1 it's broken and reports that the connection to the server could not be established.

Slack uses Janus as its WebRTC framework and the Janus Echo demo at https://janus.conf.meetecho.com/echotest.html is also broken since 59.
It reports a "DevicesNotFoundError" without any further details.

Steps to reproduce:
1. Visit https://janus.conf.meetecho.com/echotest.html
2. Click the "Start" button next to the page heading.

Reason for closing:  Fixed
Additional comments about closing:  According to the upstream bug, web cameras that report invalid FPS should now work again in Chromium 62.

Did you figure it out? (Seems to work OK for me.)
Comment by Jan Alexander Steffens (heftig) - Friday, 16 June 2017, 21:41 GMT
Do you have a camera? Seems it's only broken if video input is available.
Comment by Jan Alexander Steffens (heftig) - Friday, 16 June 2017, 21:44 GMT
navigator.mediaDevices.getUserMedia({video: true});

This fails even though navigator.mediaDevices.enumerateDevices() shows I have a videoinput available.

My notebook at home (with a "BisonCam") seems to work fine. My work PC (with an old Logitech QuickCam Messenger) is broken.

v4l2-ctl for the QuickCam: https://paste.xinu.at/DBHb2/

gst-device-monitor-1.0 for both: https://paste.xinu.at/m-jj33Xs/
