ErlyVideo connector

I've recenctly worked with ErlyVideo servers. They allow you to manage RTMP streams so you can serve them in a web page using a flash player. They work pretty well but they have a big fail: then cannot be concatenated. What do I mean by concatenate? I mean that you cannot use an ErlyVideo server as source of other ErlyVideo. At least, in my tests, the result was a corrupted video output.
As there is a big lack of documentation regarding ErlyVideo configuration and deploy arquitecture, I decided to code a little application that would receive the rtmp streams from an ErlyVideo server and send them to other one. Using ffmpeg you can accomplish this job as it supports rtmp*, but you need an application to manage all the ffmpegs and the streams and, once you are working on, it's a good idea to code some user interface. And this is the result: erlyconnect. It is a very simple application but it has been very useful.

As always, you can download it from the github repository at:
There is a README file to see how it works. Please, let me know if you find some bug or just have some doubts about how it works. Comments are always welcome.


* ffmpeg supports RTMP if it has bee compiled to support it. I used the medibuntu and debian-multimedia repositories as the standard ffmpeg of ubuntu and debian do not suport RTMP.
