Why do we not use it again? For real though, a decent 4core without hyperthreading can do the job just fine. There's also NVENC if you like using thousands of cores too.
takes forever to encode, hardly any quality difference.. doesn't respect your freedom
>>53090486
Because it had no decent encoder and still drives CPUs crazy despite your lies.
TWO pools LMAO! TWO pools
>>53090519
I don't really care about the quality since, x264 is lready good enough, what I really care for is the efficiency. Less space for the same quality is always nice.
Regarding freedom, I'm just hoping VP10 saves us.
>>53090532
>still drives CPUs crazy despite your lies.
I'm sorry for lying. It does take quite a bit to encode. It took almost 4 hours encoding an already encoded 100 minute 7GB movie, I can't imagine encoding straight from BDs. I mention NVENC, but I haven't really looked up most of the stuff, just the presets and crf.
Try watching 4K videos encoded in HEVC. It's impossible with a 960. I'm not buying a video card just to watch some videos.
>>53090793
Ok, I'll reencode that Phantom 4k test I got years ago and report back.
>>53090486
Because modern-day graphics processors don't have a dedicated h.265 decoder, like they have for h.264, so the performance suffers greatly on low end systems. People don't wanna lag just watching a video.

Good luck running it smoothly.
For 1080p right now it just doesn't make sense, its a huge burden to encode/decode it right now just so you can save 200-800mb of space.
People are making x265 stuff available online but they have no idea what they are doing, yes its more efficient but your 105mb rips of Mr.Robot manage to look like ass.
What might really push x265 might be the new bluray 4K standard, but we will see..

A year ago I made a 2.5GB encode of The Winter Soldier with x265 and it looked better than the 6-8GB AVC encodings you find on torrent sites. Everything I've seen come out of x265 looks insanely good. No issues playing back 1080p24 or even 1080p60 on a modern computer.

I'm using an i7 4790k @ stock and a Fury X and MPC-HC (had to download it just now but eh) and I got the full 60 fps & in sync with audio.
Visuals were glitched out in the very first second or so, but quickly went to normal. Not sure if that's just the file itself or my system loading it.
>>53093942
The Fury X has hardware that decodes HEVC.
The video glitching is your system. The picture is fine if you go frame by frame, but it will give you problems if you try to play it.
>>53094002
Gives me no problems when I'm playing it. Its only when I start up the video or skip to points.
And yes, I am serious. I can watch it absolutely fine with no glitching after the initial glitch as long as I don't skip - and even if I do, its only for half a second again.
>>53093942

No it doesn't. 960 is the only dgpu that supports HEVC.

You can decode 8bit 4k hevc with an modern atom.
>>53094105
at 5 fps maybe
>>53094094
The file is 10bit, you can see it here >>53092549
Your fury x only supports hevc main, that means 8 bit only.
That means you're playing 4k 10 bit content flawlessly while people with better processors than you struggle with the same file? Come on.
>>53094128
Yes, I am.
Like I said, give it 10 hours, I've gotta go work.
Once I'm back I'll prove it.

same reason people kept using mpeg4p2/divx/xvid for a while after h.264/avc came out, it's faster to encode
>>53094102
>>53093942
I toned down the configuration toframedrop=no
hwdec=no
vo=opengl-hq
ao=alsa
and get extremely smooth video playback but desynced audio. I'll try with pulseaudio next.
>>53094243
Welp, nothing changed.
I guess I can't play UHD HEVC at 60fps. The future is bright though, that video looked very nice.
>>53093814
I'm out of the loop. What did they do?
>>53092549
try with SMPlayer too, please

>>53093942
My MPC-HC does A2R10G10B10 display @ 60 FPS too. It's watchable.
I don't know how? But it looks nice and doesn't stutter.
>>53090486
>a decent 4core without hyperthreading can do the job just fine
i5 4460 here, you're full of shit op, encoding at best quality settings takes hours compared to H.264 Hi10P even with a quad core CPU. The HEVC encoder just isn't good enough yet. Playback at 720p/1080p is ok but it's not worth my time if I want to encode anything.
>>53090486
LEAVE US DAIZ, YOU SHANT PULL THE SAME BULLSHIT YOU DID WITH 10 BIT YOU BASTARD.
>>53094435
What do you need 2 bits of alpha for on an opaque pixel
>>53091036
i can play it smooth with the winddows 10 built in uwp app, but no sound, probably uses gp acceleration
>>53094128
Not him, but I've got a i7 2600k at 4ghz with a GTX 970 and it played flawlessly for me at 60fps.
So I did some configs, and it can be played smoothly with GPU acceleration.
With DXVA 2 native, i5 2500K@3400MHz and GeForce 960 it is possible.
LAV + MPC x64
Strange that the built in w10 app can only pull it off without sound, but who cares if mpc is working.
>>53094578
The encoder is working exactly as it should, it's a CPU-bound issue at this point in technology.
You're under some impression that a few years from now there will be some hyperactive version of an h.265 encoder that magically can create the content at 100x the speed they do now and it won't happen because of the encoder - if it happens at all it'll be because of some advancement in the CPU world.
Learn how this shit works before you mouth off, son.
>>53095227
I have the same settings as you and it still plays like shit.

Nvidia cuvid doesn't work, only dxva2 native.
I have a shitty dl speed, I used to settle for the 480p msd releases, hevc might be shit but they're ok for pajeet tier connections

>>53095236
We're talking about x265 here, compare it to the proprietary encoder which the HEVC devs own then tell me it was just an hardware-realted issue again. Of course it's hardware-related fagget but the encoder plays an important part in it. I never said I expect x265 to magically become faster than x264, it will never happen for the nature of the codec itself.
x265 rips are the tits. same quality as 720p x264 but with the same size of a 480p x264.
>>53097850
>same quality
no
>>53098483
This. The encoding community doesn't use x265 because it washes out fine details.
>>53097850
>same quality as 720p x264
No it's not.
The first 4k blurays ate coming out in March and they're supposedly going to use hevc
>>53098617
That and the new GPUs will push it even further. On the other hand, let Intel put even beefier Iris graphics on their CPUs and hopefully AMD can push out Zen based APUs next year that aren't shit.

>>53091036
Can't play this properly on a 4.3GHz 4770K with 32b MPC-HC 1.7.10, either with fancy madVR or with EVR.
It would probably work fine on mpv on Linux though, at least the other 60FPS 4K test file I have does, but I'm too lazy to try it out now.
>>53095948
>1836 dropped frames
Guess even an OC'd 5960X isn't enough for software decoding 60FPS 4K HEVC.
>>53091036
dumb question: can't you just use the gpu to decode?
>>53090486
too hard to use, most devices and HTPC are too low powered
>>53101663
I did that and it doesn't help very much. I'm still only getting 15 fps and the sound goes in and out.
anyone here know a video decoding library that isn't part of ffmpeg?
getting a video to play in an OpenGL context is fucking cancer
>>53094346
VP9 is like the default codec for Youtube unless.
VP9 porbalby has more hardware support than VP8.
VP9 however still takes a loong fucking time to encode.

>>53103487
a compute stick with core m featuring skylake supports native hardware 8 bit decoding for $100. upcoming smartphones will support hevc 8 bit too.
fact is 8 bit is piss easy to play and isn't worth advertising at all.
The 960 is the only gpu that actually fully supports hevc. It can play 10bit content where even $1000 chips are unable to brute force.
>>53103676

Yeah so the default Win 10 app somehow manages to play this 60 fps but it still wrecks my 4770k. I'm not really sure how though, QSV, NVENC, CUVID, DXVA2 all don't support playback which isn't that surprising because fuck 10-bit.
My MPC-HC won't play the file for some reason, audio only. Assuming I'm missing codecs.
