Hey h98, I saw in the Polaris thread you said that the *encoding* bug was fixed/closed, but not using hardware. Have you had any further response on your decoding issue (where you have to quit QT Player and reopen)? I still have the problem w/ the latest DB11 (18A389).
I've submitted a bug report as well, but have gotten no response at all. Are you submitting w/ Feedback Assistant? I've submitted 3 issues and haven't gotten a single response. Also submitted a couple back in the El Capitan beta days, no response there either. Wondering what a response actually looks like and whether I'm "doing it right". Anyway, any info about decode?
Fred
Yes, I submitted a bug report about the hardware decoding issue on 21 Aug. A few back and forth with the Apple Engineers.
Their last reply to me is on 19 Sep, and they said still under investigation. Will contact me is need required.
Anyway, don't use Feedback Assistant. You won't get any reply from there.
Use bugreport.apple.com
Is this true? According to Apple:
While iOS devices with LCD screen lack "HDR display", they are capable of streaming HDR contents. I believe if Settings | TV | iTunes Video | Download HDR Videos option is available and is set to on, your iOS device is at least capable of playing HDR contents in P3 color space.
All iOS devices with an OLED screen specify "High Dynamic Range with Dolby Vision and HDR10 content". Watching iTunes contents marked with HDR10 or Dolby Vision look vastly different to my eyes on iPhone XS.
I’m out of town, but will check it out next week when I am able. Hope they’re right about that!
Tested, and not fixed. They do make some changes indeed. We were able to play those high demand HEVC video at least once. But now, not even once on the latest beta.
So, my suggestion is do NOT rush to install the 10.14.1.
Anyway, Apple closed my bug report, and suggested me to raise another one. Because the issue is now “changed”
Strange, in my case, all QuickTime, IINA, VLC can do hardware decoding smoothly. And QuickTime is the best because of no over saturation issue.
QuickTime doesn't convert from HDR to SDR, you colors in QuickTime are not the one intended, they are simply wrong. Colors in other apps are wrong too, if you want to watch HDR, buy a HDR monitor/TV instead of down converting everything to SDR with a random algorithm.
I have a 10bit HDR monitor
But thanks for the info about convert HDR to SDR. That explained the colour difference.
That's good, but neither QuickTime Player, mpv or IINA can output HDR on macOS right now (from what I remember, one way to check is to playback the click on a HDR TV set, and see how the colors compare to the Mac)
I may boot to Windows and check that later. Even I can't compare the video side by side (Windows vs macOS). But the difference should be very obvious (otherwise we don't need 10 bit or HDR from the very beginning

Just did the test, the colour in QuickTime Player actually looks correct (if compare to the Windows Media Player Classic)

Windows Media Player Classic doesn't support HDR output, neither HDR to SDR conversion if you don't install some other plugins.
It would be easier to try on an actual TV.
Don’t have to manually activate HDR mode for HDR videos or games in Windows now. The October update automatically applies correct color profiles to the desktop and HDR contents.
Windows dark mode is such a mess. They can’t decide to make it jet black or gray.
Viewing videos and big image files much faster than Mojave though.

Updated to 10.14.1b3 yesterday...same issue. High CPU usage, from around 300% to 600%, depending on video. Also, GPU usage (in Activity Monitor) spikes to near maximum, which is more than when it is actually using the GPU to decode.
I updated my report in Feedback Asst to show that it won't even hardware decode on the first try now.
Please make sure you report that via bugreport.apple.com as well. That's the only method I get Apple engineer's reply so far.
LOL...oops, I went ahead and did macOS + SDK > QuickTime. I guess if they don't like it, they can relocate. But it IS in QuickTime Player, so should still apply. FWIW, I also submitted a "Suggestion" requesting H.264 decode/encode acceleration as well (just as I did in Feedback Asst).
Welllll....this sucks pretty hard:
Got the same response for my other feature request feedback:
Wouldn't be so bad if we hadn't already *had* HEVC decode working in 10.14.0. Oh, and Windows. Boo.
