Hi,

Has anyone tried a similar exercise? Would really appreciate any cues from
everyone...

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

[Mert Gedik]

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...

Hi,
I didn't try this. Sorry.
If you don't get any answers, it means that no one knows.
Or may be the guy who knows is unfortunately in vacation ;-)
From my personal and humble experience, if someone on this list has an answer, 
you usually get it fast.
