Use RTMP over port 80 or RTMPT over HTTP, what would be best?

Question

We currently use CloudFront Streaming distribution with JW Player 6 and the RTMP protocol. However, some of our corporate users have told us that they can't see the videos and is because they have RTMP's port 1935 blocked.

CloudFront support RTMP streaming over port 1935 and 80. And it also supports RTMPT streaming tunneled over HTTP.

So I could choose to stream RTMP over port 80 or RTMPT that uses HTTP.

Between these two, what option would be best to have better performance (and less problematic and error-prone) while avoid being blocked by firewalls?

Thanks!

Answer 1

I don't see any obvious problems of running RTMP on port 80.

Using RTMPT potentially and in theory will increase the latency, (see this from Adobe: http://blogs.adobe.com/connectsupport/tunneling-with-rtmp-encapsulated-in-http-rtmpt-should-be-avoided-as-it-causes-latency/). Although in my real experience the difference was not that huge.

However, what I would do is always try port 1935 first, and if it failed then try port 80 by using Cluster plugin. But again, there should be no issues in running on port 80.
