In this example, I have a 2 vs. 1, but it appears any number for those\r\ntwo are applicable.\r\n\r\nNow, the really interesting part is that this behavior is true for both\r\nKurento H.264 on Ubuntu and Mac OS (Firefox or Chrome) .\r\nHowever, if I use VP8 (Chrome) on Kurento, I see that this issue doesn't\r\nexist for Mac OS client (but does exist for latest Ubuntu client).\r\n\r\n\r\nIs there any explanation you can think of for this behavior?\r\n\r\nAnalyzing the working SDP vs. non-working SDP (remote and local),\r\nI don't see any big difference.  And the byte counts show 0\r\nfrom about:webrtc for the test webcams that generate the data.\r\n\r\n\r\n--- \r\n\r\nThis is mainly a copy and paste from my post in kurento groups.  Sorry I didn't have time to embeillish it but over time I may come back if I find more time to gather more info.

I'm using VP8. My configurations are:\r\n\r\n- KMS A in host machine (Ubuntu 14.04).\r\nVersion: 6.1.2~1.g18ab837\r\nFound modules:\r\n        Module: 'core' version '6.1.3~32.g30d3f45'\r\n        Module: 'elements' version '6.1.2~22.g5c261e9'\r\n        Module: 'filters' version '6.1.2~2.gafec4f4'\r\n\r\n- KMS B in virtual machine (Ubuntu 14.04).\r\nFound modules:\r\n        Module: 'core' version '6.1.3~26.g4dee71d'\r\n        Module: 'elements' version '6.1.2~21.g21f6b13'\r\n        Module: 'filters' version '6.1.2~2.gafec4f4'\r\n\r\nMy test uses java client but I'm not able to reproduce your error. Can you see any error in the browser console or the media server logs?\r\n\r\nAnyway, for your tests, Chrome doesn't support H264 in webrtc. That test can be done only in Firefox.\r\n\r\nRegards.\r\nDavid."}}
