Detect hard-coded RTMP ports (that break tunnelling)

[jeroen]

Here's the feedback from a customer using Wowza:

Every now and then (perhaps once every 5-10 plays of the video), JW Player shows the error:

Application folder ([install-location]/applications/:80) is missing

This has come from Wowza, and we can see it in the Wowza error logs. If we look in the Wowza access log, we can also see the following (this is an extract of a few of the columns):

[any]	1935	rtmpe://avtest.derby.gov.uk:1935/vodsecure	10.132.36.67	rtmpe
[any]	1935	rtmpe://avtest.derby.gov.uk:1935/vodsecure	10.132.36.67	rtmpe
[any]	1935	rtmpe://avtest.derby.gov.uk:1935/vodsecure	10.132.36.67	rtmpe
[any]	1935	rtmpte://avtest.derby.gov.uk:1935:80/vodsecure	172.16.1.88	rtmpte (HTTP-1.1)
[any]	1935	rtmpe://avtest.derby.gov.uk:1935/vodsecure	10.132.36.67	rtmpe
[any]	1935	rtmpe://avtest.derby.gov.uk:1935/vodsecure	10.132.36.67	rtmpe

I’ve highlighted the rows with the problem – My hypothesis is that due to a busy network or server, port 1935 isn’t responding fast enough for JW Player, so it’s trying port 80 instead, but the problem is that it isn’t stripping off the :1935 port number first. This causes Wowza to think that the application name we are trying to access is called “:80”, instead of “vodsecure”.

This specific issue should be fixed by detecting (and stripping) the port number in the tunneling logic. That logic should see the :1935 and replace it with :80 instead of amending :80.

In addition to this, I'll also extend the time the player allows the server to respond before moving to rtmpt. That's part of #1151

Example:

[jeroen]

Provided RTMPT kicks in (see #1151 for that), the player now does see hardcoded ports. So when an original streamer was defined like this:

rtmp://myserver.com:1935/app

The 5.4 player returned this streamer for tunneling:

rtmpt://myserver.com:1935:80/app

But the 5.5 player returns this value:

rtmpt://myserver.com:80/app
