Hi Hector,

Yes, that is what I was wondering myself. But, from my Googling of this info, 
it looks like I have to write the ANE in C or Java. So, does this mean I have 
to write a Java/ObjectiveC class that invokes ffmpeg? Or is there a simpler way?

Thank you again for helping me out.

- David

For mobile you'd need an ANE, as ffmpeg is used as a library in that case.
