Hi,

I am testing EO.WebBrowser to include it in .NET project for WebRTC. I've made simple app and try to run page
https://test.webrtc.org/.

When I click start button it runs through audio test succesfully but immediatelly fails (for a second or two empty page and than shut down) when it starts with camera tests.
In browser I dont have any problem with running test. I confirm that on both win7 and win10 on Chrome and Firefox.
It doesn't throw any exception, it just exits with code 0...
The same results I get with sample application TabbedBrowser.


This is version of Chrome and EO component.

Powered by EO.WebBrowser for .NET (v18.1.7.0) -- a Google Chrome based browser engine for .NET application.
Chromium 62.0.3202.9
OS Windows
WebKit 537.36 (@e0870e19d377d75fd6d32bdb84fd9ee4a5f35c60)
JavaScript 6.2.414.2
Flash
User Agent Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.9 Safari/537.36


PS. I don't think it has problem with camera itself, when just trying to make local streaming with HTML5 and JS it works but WebRTC test fails.

Hi,

We've got the same issue with the latest build on our app, the 2017 version works well on the same page (https://test.webrtc.org/)

Hi,

We are able to reproduce the problem with test.webrtc.org but we have not been successful in isolating it due to the complexity of the test page. We tried to run individual test and they seem to work fine. Does either one of you have a simpler page that we can use to reproduce the problem? If you do please send them to us. See here for details:

Any help would be much appreciated.

Thanks!

Hello,

Other than a simpler page to reproduce the issue, is there anything we could provide? This is a blocking issue for some of our clients so we'd like to see this fixed as soon as possible.

Regards.

We are not sure what we can do beside a simple test page. The crash is in the browser engine and normally its not practical for us to fix issues in the browser engine due to the enormous size of the project. However if you can provide a simple test page, we can debug into the browser engine's source code to see if we can narrow down what triggered it and maybe find a workaround for you.

You could use https://appr.tc/ for debugging the crash. It's a more simple test page then the previous.

Hope you could resolved this issue very soon because it's a very blocking issue for us too... :(
