OpenMAX and Video Acceleration

Hi,

I’ve tried forward-porting the ffmpeg changes for OpenMAX support and compiling them as part of Debian packages.

The main difficulty I’ve run into is that the OpenMAX headers shipping in Debian stable are the Khronos headers, and Debian unstable does not have OpenMAX headers anywhere (and disables OpenMAX support in ffmpeg).

I am tempted to just package the OpenMAX headers from Android so the interface is defined, but I’m wondering if that is the best course of action, if it makes more sense to use Vulkan as an interface as that is at least maintained, or if the correct answer is “both.”
