I read in some threads that VLC already supports hardware decode. Even a VLC developer said this. To me and to my specific usage, VLC is pure horses**t. It's the worst player being intensive resource hog that doesn't seem to think about battery at all. I found IINA and have been using it since. It's so far the best option. I could see where it supported the hardware acceleration as it showed in the Inspector - "Hw Decoder: videotoolbox" and in other places where it didn't was shown as "Hw Decoder: no". Now that High Sierra is launched, VLC is still the same, kind of raping the battery. VLC doesn't matter to much since I won't be using it anyway. But... in IINA, I was expecting to see some changes. But I still can't play UHD HEVC high bitrate 10bit stuff. I see what most people in the community are doing to test 4K playback - downloading samples, transcoding, muxing etc. It typically isn't the case for me. I WOULD PLAY/CONSUME 4K MEDIA CONTENT (MOVIE/DOCUMENTARY). I have some UHD titles and all I care about is playing those files flawlessly and taking in all the UHD goodness. I still can't do that. The following are some of the high bitrate HEVC 10bit UHD titles that I tried to play... Planet Earth II 4K Revenant Star Trek Into Darkness None of them are playing with hardware support at all. What gives? Are we to expect another HS update? Should we expect an IINA update that supports hardware acceleration? WHY AREN'T PEOPLE TALKING ABOUT IT ?
