I have make several tests for this case.

• When running in local host, there is no problem. There is no freeze.
• When running in remote host, there are some freezes. In this case, I've checked that bandwidth between server and client is not high enough to play the stream. It's already reported by the server.
• When running in remote host and known that there is enough bandwidth, there is no freeze.

From my point of view, the network between client and server is not good enough to play this WebRTC stream smoothly.

Possible solutions are

• Decrease quality. Decreasing bitrate(3.5Mbps), resolution(HD) and framerate(25fps) accordingly still provide good user experience that most of the users don't notice.
• Add at least 2 adaptive bitrates to the server side. To serve good quality to high bandwidth users and lower quality for users having lower bandwidth
