Title: HEVC Nvidia Drivers High Sierra 10.13
Post by: tomtomgps on June 07, 2017, 06:03:05 PM
Does anyone know if NVIDIA will provide HEVC decoding on High Sierra  with their web-drivers?
Since the 950, 960 and all pascal GPUS support it natively it would make sense if Nvidia enabled H265 acceleration on Mac.

I highly doubt it.  Apple has been using Intel for all video-related stuff for a long time.

Now that I think about it if NVIDIA doesn't have HW decode support  in their drivers does that mean that the next version of the Mac Pro won't be able to decode 4K? Since the Mac Pro will probably use a xeon cpu without an intel GPU.  IF the Mac Pro doesn't support 4K decoding, it would render it a tough sell.

You can better believe that thing will be powered by AMD, apple isn't showing nvidia any love right now.

tomtomgps is the winner.  This will be addressed either by Apple using a part with integrated GPU (they exist), or Nvidia will roll this into the driver.

I'd bet money that NVIDIA isn't going to write a video driver until Apple buys their chips to go into a system that needs a video driver (i.e. the iMac Pro or modular Mac Pro).

My knowledge of hardware decoding is pretty limited but the nvidia driver probably shares most code across platforms.  If apple provides an api for hevc/vp9 decoding thn i think it won't be too much of a big job for nvidia to implement something.  I wouldn't be surprised if Nvidia only enabled hevc/vp9 for pascal gpus though. i guess we will see in september/october

The driver's already been written, it's in beta status.  There's no reason to think this feature won't be added.  Look for it when High Sierra goes live would be my bet.

well it seems that Nvidia has decided ti skip havoc hardware decoding support ...

Pretty sure this has nothing to do with NVIDIA.  Apple's HEVC stack is all CPU based, and only runs on modern Intel CPUs (Kaby Lake, perhaps Skylake too).

The only app I know of, able to play HEVC files, is VLC. Still, on macs like my mac pro (2010, GTX 980), this is a no-go as video freezes, probably not being decoded. Check some samples here: http://demo-uhd3d.com.

IINA can play it but it's not smooth... https://lhc70000.github.io/iina/ (https://lhc70000.github.io/iina/)

I don't know what the heck this means, but Cuda Driver 8.0.90 WORKS in High Sierra ???

Nice catch.

I'd lov e to confirm it but I still can't get the High Sierra Web Driver to work so until then...

IINA can play 4K HEVC video on my Mac smoothly. In fact, it perform much better than VLC most of the time.

MPlayerX can also play HEVC video.

P.S. I always use .ts container for HEVC video because my LG TV's internal player only accept .ts for HEVC video.
