Good to see support for H265. Can anyone confirm how deeply this is implemented? Will quicktime now play H265 files and are MKV's now supported too?

Sorry just to be clear, can anyone with the beta installed confirm if QuickTime can now play MKV files? I use VLC currently but would be nice for the system to be able to play them natively.

MKV is a wrapper. Most likely you have been playing h264 files because I haven't seen any support for h265 in VLC.
 
HEVC relies on hardware for decoding, and software that has support for HEVC.

If you don't have a Skylake CPU, then it's software decoding, and this will choke your cpu heavily on anything more then 1080p on a low bitrate.
If you can't play jellyfish-110-mbps-hd-hevc.mkv from http://jell.yfish.us/, then you don't have hardware support available / enabled.

Full hardware support if also available on AMD GCN 3rd gen and Nvidia 1000 series (+ GTX960 only), but this is with proper drivers.

Quicktime on 10.13 Dev Beta will not play that file.

VLC does not support h265 and certainly wouldn't be remotely possible years ago. Please don't confuse codecs with wrappers.

VLC support H265 at least since 2.2.0, however the free lib265 decorder not well for high resolution,
but it work for low bit resolution up to 1080p very well.

Improves support for new HD codecs, VP9, opus and H.265/HEVC, for decoding and for encoding.

I'll see, but the whole point of h265 was to play much higher resolution content than HD

Notice the word "improves".

Can you kindly just download a 4K h.265 file from many online sources and look at the results instead of having a useless internet debate.

You're missing their point. Here's the video linked earlier in this thread, playing back in VLC on my 2013 Mac Pro:

Their argument is that VLC supports it, not that it works well.

Your posts give the impression that you're trying to argue that VLC won't open the files and play them at all. They do open and play though, there are just quality issues.

Note that this does not answer OP's question, I'm just trying to clarify that point that VLC can read those files.

Ya VLC does open it. Play it albeit sort of sloppy as it does support h.265.

Just not very well. Especially if you're playing a 4k h.265 file.

As far as the OP.

QT in this beta seed will not open the file in question.

However QT will export a raw file using the h.265 codec. using the .mov wrapper.
It will also export as 4k video.

I've seen this before in new Dev beta seeds. Stuff is kinda lacking in certain areas but as the builds get more refined so do the apps.

I didn't refute it can't open them. I know full well that it can but if the playback is awful and impossible to view then that's as useless as not being able to open them.

It might be the file linked earlier. I've played it a few times using VLC and the beginning was choppy.

Then I searched around and found these awesome files.
They play quite nice on my 2013 Mac Pro.

The problem is not 720p, has any "recent" computer can play them with vlc. (software decoding)
The problem is reading 1080p@30fps 10bit HEVC files and up.
