No video stream on some connections

[dnish]

Hey, I'm having a strange issue when using coTURN as a relay. I'm forcing each connection to use TURN by enabling iceTransportPolicy: "relay" within my Javascript code. After that I try to establish connections between my 2 clients (Chrome on Mac and Safari on iOS). This works most of the time, but sometimes there is a strange error: Chrome receives a stream, but only the audio one. The video is black and empty. On Safari everything is working perfect, I get the audio and video tracks from Chrome. The chrome://webrtc-internals/ shows that there were no video packets received (everything is zero). If I do a camera switch on Safari (renegotiation), Chrome also starts receiving a video stream. When I disable the relay, I don't get this error. There are no errors shown within my Javascript code or on syslog. Has anyone an idea what could cause this issue? We are using version 4.5.2.

Are you using a single PeerConnection with BUNDLE enabled for audio and video?
Can you share the whole webrtc-internals dump?
