Code Sample: simple media player with MLT++

[skullmunky]

I'm just excited I figured this out, since the documentation is a little sparse so far, and thought I'd share this fun little code snippet. One of the things we all want to be able to do is play and manipulate video. This is often a bit of a challenging task, but the MLT toolkit makes it very easy. The MLT wiki has a simple video player example written in C; this is a conversion into C++ with the MLT++ library. It just opens an SDL window and plays the video file you give it.

To use MLT, you should probably be running 9.04 (or higher). Install libmlt++-dev.

Enjoy!
