Strange WebRTC Issue

Hey all, I know this might seem like a repeat of every other WebRTC issue thread out there, but I think I've got a unique case on my hands. A couple weeks ago my friends and I hosted a perfectly successful session using Roll20 for cams only (we use a separate app for audio).  Since then, however, I have not been able to get cams to work on my Windows 10 computer (which I was using for the successful session).  Latest version of Chrome, no extensions - everyone else can see everyone's video fine, but this one computer will only display avatars. I decided to do some poking around and opened up the Chrome dev console.  I noticed that every time a player with cam on connected, an error was being thrown: Uncaught ReferenceError: inMediaStream is not defined at i.<anonymous> at i.n.emit at i.addStream at RTCPeerConnection.t.onAddStream I checked out the pretty-printed source and it does appear like there is an attempted assignment of an undefined variable, but I wasn't able to glean much more than that. The odd thing is, I decided to load up Roll20 on my Macbook Pro and everything worked perfectly fine.  It's working fine for all other players in my game.  It even worked fine on this computer a couple weeks ago. I've tried nearly everything I can think of, including all the suggestions in the troubleshooting page, before posting here - so I'm hoping somebody can provide some help or at least point me in the right direction!  Thanks!

Could you please carefully work through the first three steps of our guide to Solving Technical Issues ? Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Tried. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Tried.  Step 3: Clear your cache tried If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) The console log will help us find out if it is not connecting. Did you reapply the camera permissions? Click on the padlock to the left of the url and click on the camera menu then select allowed.
All three of the first steps I have definitely tried multiple times. Browser: Chrome 58.0.3029.81 Operating System: Windows 10 Javascript is enabled Windows Defender (have tried turning this fully off, no change) No add-ons or extensions Full verbose console log: The error I described can be found at the end there - I have one player connected with camera on. This error happens whenever attempting to connect to any player with a camera - if I use the Reconnect button, it will happen again. If I try to reconnect just the one player, it will happen again

Thank you for bringing this to our attention, Zak. We discovered a misnamed variable in our code. This has been fixed.
