[Libav-user] how to activate videotoolbox hw decoding ?

Hello everybody,

I have a video player written for iOS, and want to add hw decoding feature.

I can build the latest ffmpeg with videotoolbox support, and my project now
needs videotoolbox.framework to be linked. I think, this shows that
videotoolbox is enabled in ffmpeg successfully.

What I wonder is how can I activate this ? I see that the cpu values are
not changed so I guess, ffmpeg still uses CPU decoding

Do I need to set a property like enable-hw or init any API before decoding ?

Any clue is appreciated...
