Is this because the GPU doesn't support it? The CPU? Or the software. Should we have waited for the Kaby Lake processors?
 
What do you mean it can't? Have you tried to and were unsuccessful? You should be able to play them but CPU and/or GPU load will be higher than if you were playing them with a Kaby Lake machine which has builtin hardware decoding for those files.

VLC should play them back fine if QT won't.

Just got a '15 MBP 13 Retina i5 16GB 512GB and VLC doesn't play 4K smoothly. It displays the first few frames and only plays sound after that. I was surprised. I wonder if there's a better app to play 4K video.

Same as Lamina above; very choppy or stuck on a frame with sound playing fine. Most of the time it sticks on initial (black) frame.

h.264 4K files play fine, but most 4k files are h.265 due to better compression.
 
according to this thread skylake should be able to ...

Whatever that threads says. Intel Says No You can not period unless you have Intel 7th Gen. Let's not misunderstand Playing a 4K YouTube video. This means UHD Premium 4K streaming because no one is gonna fill up their hard drive with a 4K UHD movie. So it has to be streamed.

http://www.intel.com/content/dam/ww.../infographics/how-to-watch-4k-infographic.pdf

Content providers control it they set the rules h.265 needs Intel 7th Gen no way around it its baked in. Don't even try and logic around it by using the GPU.

What's done is done. If Steve Jobs was Alive he would have waited 2 more months and Lauched with

Kaby Lake, DDR4 HDR 4K h.265 support and made a big deal about it. As Intel has.



4K UHD Entertainment: Thanks to the new media engine in all 7th Gen Intel Core processors, it is possible to stream 4K UHD movies and TV shows7 on services such as Netflix* on a computer for the first time. This means that critically acclaimed titles like “The Crown” and “Stranger Things” can be watched at home or on the go in brilliant 4K on your 7th Gen Intel Core computer. With the availability of other premium content providers like Sony* Pictures ULTRA, FandangoNOW* and iQiyi* coming in 2017, your 7thGen-based PC is now a 4K theater.


Steve Jobs would have gone on and on about how Amazing having a Full theater aka Netflix and a MacbookPro are connected to a 55" 4K TV.

Now we get to hang our heads in shame instead.

Hmm, this is actually pretty disappointing if this is going to be the standard for 4K delivery. I work with 4K XAVC-S 100mbit files all the time in Premiere, but those are 8 bit, and XAVC-S is a different animal than h265 which is brand new.

Oh well? The new MBP is a screamer otherwise.

It's not that likely Steve Jobs would have waited for any kind of video standard. He never budged on
Blu-ray. In any case, people are likely to figure out a way to handle the new standard if they care.

I'm beginning to feel the same. Apple seem to have lost it's way. I bet 90% of MBP buyers would have been happy to wait until March and Kaby Lake processors - I now have a £3,000 machine that can't play 4K h.265 videos!!! What a joke!!

I am seriously considering sending it back and getting an iMac in the spring. I don't *need* a laptop until the end of next year when I go travelling - so I could just sell the iMac (and probably lose less money on it) and then pick up next years MBP model.
 
Hay guyz ---!!!

Where can I find 4K H.265 videos?

Are they on Youtube? Or maybe Vimeo?

What if my cable internet is still too slow to stream 1080p without stuttering?
 
Well, technically the newer NVIDIA Cards and also AMD Radeon Pro 460 can play 4K H.265/HEVC, but Netflix currently is only build on a Microsoft DRM Solution, which only supports it through the Intel Kaby Lake CPU+Edge Browser.

I think to test it, you need also a Movie Player that supports the hardware acceleration.

Yes. I barely go outside these days. I can feel the gaze of passers by. "You don't watch Netflix in 4K on your MBP?" - their eyes cut like swords as they judge me, silently. And that scene from the Song of Ice and Fire repeats itself in my mind: Shame! Shame! Shame! Shame!


Seriously, people, do you hear yourselves?

Most of us have larger external displays.

So does this mean apple needs to release a new Apple TV to watch 4K content?

Yes, but this has nothing to do with Kaby Lake. AppleTV is, basically, an iOS device, and the rules are quite different there - one of the few upsides to having a closed file system (yes, there are some upsides, actually) is that content providers are more happy there, the piracy protection is built in from the start. However, the AppleTV is a 1080p device and I'm sure Apple is preparing a 4K update that will come with HDMI 2.0.

Don't Kaby Lake processors have dedicated hardware decoding for h.265? This would explain. I may be wrong and would like to be corrected if so.

Edit: Found this from PC World:
The other important aspect of Kaby Lake is Intel’s transition to a new video engine. According to Chris Walker, the general manager for mobile client platforms at Intel, the web’s content platforms are moving to HEVC and VP9 for video encoding and decoding—and at higher resolutions. Skylake accelerated 1080p HEVC encoding and decoding natively in hardware, but it lacked dedicated support for 4K HEVC encoding/decoding at 10-bit depths, or VP9 decoding—two things that Kaby Lake does natively in hardware.

These advances are important for the same reason that Netflix and Google have led the way toward using both codecs: They provide equivalent video quality at a fraction of the bandwidth, especially as 4K video becomes more widespread. On Monday, for example, Netflix performed an in-depth technical examination of three of the most popular video codecs. Netflix found that HEVC delivers all of the video quality of the older AVC codec that Skylake supported, but at 50 percent of the bandwidth.

That means the amount of data your bandwidth cap chews up on account of video streaming could be half of what it is now, without a noticeable change in quality—but it would require significantly more computational horsepower from your PC. What Kaby Lake promises is that the new dedicated video block won’t actually impede your PC’s performance.

That translates into two advantages, according to Intel: first, a tangible improvement in video decoding and encoding. Naturally, a Kaby Lake system will be able to decode 4K video at 60 frames per second—or up to eight 4K streams at 30 fps. But even the ultra-low-power Y-series will be able to encode 4K video at 30 frames per second, Intel said.

Otherwise, simply playing back video will consume far less power than before. Intel claims that the power consumed by the CPU and GPU combined will be up to 20 times less than in Skylake, resulting in a whopping 2.6 times more battery life when playing back HEVC 10-bit video on a notebook with a 4K panel. Streaming VP9 video on YouTube will see smaller, but still-impressive gains: a 1.75X improvement in battery life.

Quite glad I held off on these new MacBook Pros. I get the feeling the next revision will be the one to go for and address a lot of user complaints. Typical Apple first-gen hardware situation.

And most of computers can't play Netflix 4K on them. So? You do know that even Kaby Lake MacBooks WON'T be able to play Netflix 4K because they don't run Edge on Windows 10. Blame Netflix.

Read the early Kaby Lake reviews - it is a lazy CPU upgrade done by a company (Intel) who is enjoying the lack of competition. Almost no improvements.

If you want to watch 4K Netflix, get a 4K TV. You don't even need a computer, because all 4K TVs come with the Netflix app built in (as far as I know). That's it. I wish I could watch it on my iMac 5K. It has a 5K screen! It would look beautiful. But I can't, because Netflix won't allow it.

So, even if Apple waited for Kaby Lake, no, you still wouldn't be able to play Netflix. Sure, you could argue that, I dunno, Tim Cook could've negotiated with Netflix to allow it, but as you can see with Netflix being absent from the new TV app, business negotiations are not that simple. Apple has been waging war with content providers for years - and I don't find it strange that Netflix allows 4K ONLY on a Microsoft browser (or you think Chrome is not good enough for 4K?).
 
Appears to be an issue with hardware acceleration software.

I used VLC to play the "jellyfish-200-mbps-4k-uhd-hevc-10bit" file on my tbMBP 2.7GHz / 455...

Trick? Turn down the playback speed to the lowest setting.

That means it CAN decode HEVC h.265 4K at 60fps...

And my CPU usage by VLC went up to around 300-340%...not even CLOSE to maxing out all 4 cores. Not sure about the dGPU...
[doublepost=1483890985][/doublepost]I found the solution...Apple just has to throw a couple of these babies in the next MBP!!!!!


All problems solved!

I don't care about Netflix, I care about (editing and) playing 4K videos encoded in h.265.

Yep because VLC is not utilising the available GPU hardware acceleration for h.265 decoding, and the CPU doesn't support it.
