I just set up a couple of wordpress-sites and ended up using your plugin to stream video for flash and html5. I started "flipped classroom" for pupils with ipad, android tablets and PCs - and your plugin is just perfect for the job. With it I don't have to use YouTube and I have a lot more control over how I'm doing things.
I had to recompile ffmpeg for centos v6.3 to get the ffmpeg conversion to work.
This is just a thumb up-comment ;-)
