WebRTC Logs added in the folder.

Comment 7 by sprang@chromium.org, Mar 15 2018 

Not sure what this means.
Can you check chrome://webrtc-internals and see if/where there's any frame rate going to 0. Input / encode / receive / decode / render.

Comment 8 by rantonysamy@chromium.org, Mar 16 2018 

I added the webrtc event logs in the folder at #2, but I am trying the scenario again and get you more logs and graphs where its failing. Hope that helps.

Comment 9 by rantonysamy@chromium.org, Mar 16 2018 

Can you also check Issue 663452, says relay is going black as Intended. In that case I close this issue ?

Comment 10 by sprang@chromium.org, Mar 19 2018 

I guess so.

Sounds like this issue was going to be closed? Reopen if I misunderstood.

Comment 13 by rantonysamy@chromium.org, Mar 26 2018 

Yes thats right. Thanks.

Comment 14 by vasanthakumar@chromium.org, Apr 3 2018 

Multiple relay works fine in Windows machines. Blacking out seems to happen only in chrome books. Is this expected behavior? 

66.0.3359.46 /10452.19.0 Windows 7 (Lenovo Thinkpad X1 Carbon), Windows 10 (Asus UX430x)

Comment 15 by vasanthakumar@chromium.org, Apr 4 2018 

I have got the reply for that behavior in Windows machines. Thus let this ticket remain closed. 

@Emircan's explanation:

It is intended for HW decode
HW decode is possible on all platforms based on hardware or codec
That demo page in the CL has VP8 by default which is available on CrOS
If we were to choose H264, we can reproduce it in Windows too
