Multiple RTMP Outputs Plugin For Max

Max is a platform that is not only easy to use, but powerful in what it can do. The same goes for the plugins that are made for it. RTMP Outputs is one of these plugins and has been extremely useful right out of the box. If you are looking to have multiple RTMP outputs, then this could be the plugin for you.

I’ve been working on my own video streaming plugin for some time now. It’s called RtmpPlayback and it can stream to multiple platforms at the same time. I didn’t want a single plugin to do this, so I broke it out into a sub-component that could be reused for other developers who might also want to support multiple playback engines.

Everyone loves that wordpress works so well. And the features keep getting better and better, which is good news for those of us who don’t like to spend hours planning websites from nothing. However, with all these great features, it’s time we started learning how to exploit them.
