Yes, more or less like you say. FFMPEG is a library on mobile, already in ObjectiveC on iOS, and I think it's written in C for Android and the NDK has to be used, you can still use it from Java, but it makes things a bit harder, I guess there are already some easy-to-go libraries out there for it.
You'd have to design and write AS code that communicates with native code (Objective C or Java) that you have to write as well, and that native code would then use the native ffmpeg library, you can check the documentation for making your own ANEs here: http://help.adobe.com/en_US/air/extensions/air_extensions.pdf On Wed, Jul 1, 2015 at 7:26 PM, David Frank <david.fr...@on24.com> wrote: > Hi Hector, > > Yes, that is what I was wondering myself.
