Does this use HW decoding?

[samskiter]

I see that you recently updated the ffmpeg version - I just wondered if this means the decoding is now done via HW acceleration for h.264 on iOS8+ (where the HW accel is exposed to devs)?

I wonder it too, but according to latest ffmpeg sources there is no mention about new APIs.
But i saw some patches and you can assemble ffmpeg with HW.

Hi guys,

There are ways to make hw decode in iOS 8 but this must be made in a wrapper class and some of the new available methods from the iOS SDK must be used instead of those from ffmpeg.

I will work on this next month and I will let you know about the status.

Kind regards,

Just asked on IRC and not supported on Mac or iOS on either ffmpeg or libav. Found an old patch for libav (https://lists.libav.org/pipermail/libav-devel/2012-September/035830.html) to support video toobox on mac osx but it seems to have been lost to the ether...

Update: as a result of poking on IRC, I think libav may look at supporting HW decode soon too so it may be a no-op for you @dragosperju

p.s. are you using ffmpeg or libav here? I just learned they are often mixed up
