Youtube 5/8K60? (VP9?)

[psyside]

What video card is needed for normal to smooth 6/8K60 youtube playback?

Does the cpu matter and if not, are the Pascal 1030 and so on enough to do it? does the browser matter?


I have tested it on a G620 and 1050 ti, while it was far from perfect, (stopped many times, then resumed normally) it did play much better compared to my i5 2400/GTX960.

Sorry if this thread is in a wrong place, please move it to the correct one.

Example is anyone being able to play this smoothly with chrome or any browser?

I can play that video smoothly but the Hardware Video Decoder (VID) usage is over 90%. I have a Titan X (Pascal), i9-7900X @ 4.7GHz, 32GB DDR4-4000, Windows 10 1709 build 16299.192, Chrome version 63.0.3239.132.

I expect any Pascal GPU would be able to play that video with the exception of the 1030. The 1030 has very low memory bandwidth (FB usage in Afterburner). I am using about 7% of my 480 GB/sec while the 1030 has 48 GB/sec or 10% of my memory bandwidth in total. That seems too close. There is a similar problem with GPU usage; my GPU usage is around 7% and a 1030 has 10.7% of the CUDA cores (384 v.s. 3564) which are also clocked a little slower. A 1050, with its 112 GB/sec and 640 CUDA cores, seems much much more likely to avoid problems.

Here are my Afterburner graphs while playing most of that video, you can see the work is done almost entirely by the VID but two CPU cores and the GPU are slightly active:

Edit: I would blame the G630 for your issues while using a 1050 Ti, that is a very old CPU at this point and I did see some CPU usage associated with playback that the 1% CPU usage in the graphs downplays more than it should. That percentage is for all 20 threads and it was often a percentage point or two higher.

hello dude. Thanks for jumping in, sadly your cpu is way too powerful lol. I'm a beginner with this stuff, and i still dont understand - if i got Pascal, and weak cpu i still cant play this 8k videos? then what is the point of full decoders/encoders?

[Asmodian]

Well there is weak and then there is weak. I cannot play this video without hardware decoding and a 4790K would be plenty with hardware decoding.
This is what it looks like if I disable hardware decoding and playback is pretty choppy:

[psyside]

Thanks for doing that, it really helps!

How do you disable or enable decoding?

What i dont understand is, how come it starts, and the gpu is used like 40%, then in the next 10 seconds in drops to 0-5, and it start to stutter like mad.

[Asmodian]

There is an option in chrome (near the bottom of the advanced list) "use hardware acceleration when available" that defaults to on.

I am not sure why your GPU usage and performance would drop like that, there could be temperature issues, bandwidth issues, or something else. :(

[psyside]

I got 150mbps connection, but the upload is 5mbps, don't know if that changes anything. Temerature is not an issue, i monitor the temps almost always :(

The only thing is left is the GPU/CPU, i got HW accelration enabled, and even another features enabled -

Is anything maxed out in Task Manager? A CPU core pegged at 100% or something in the GPU maxing out? :confused:

My Chrome option doesn't look like that:

I have an i7-7700K here. Hardware decoding does not support 8K VP9. CPU decoding via ffmpeg (no playback) gives 45-47fps. Threads are not saturated (80-90% utilization). So, I think CPU decoding is out of the picture unless you have the latest and greatest.

ffmpeg command for reference:

ffmpeg -i "Peru_8K_HDR_60FPS_(FUHD).1La4QzGeaaQ.VP9-OPUS.mkv" -c rawvideo -an -f null -

Yes, the cpu is maxed out, the gpu is idling, or around 10-15%

A 4GB 1050 Ti would be my recommendation, you need full hardware decoding to watch 8K and that takes a new VID. A 2GB 1050 would probably be able to do it too but I worry about a 1030 being a bit too slow for smooth playback of 8Kp60.

I believe the 1050/1050 Ti (GP107) have a very good VID along with plenty of memory bandwidth.

[psyside]

Yes, i will be getting the 1050 ti in few days, i just HOPE it wont pause again like at my friend home, when his G620 wasnt being able to run it smoothly even with the GTX1050 ti.

Does SSD play a role in it?

GTX1050 will be not enough for madVR afaik?

[Asmodian]

No, a SSD has no effect on video playback.

I recommend against the 1050 for madVR. I wouldn't like anything below 3GB for madVR today. The 4GB of the 1050 Ti is nice to have, along with more memory bandwidth and cores. Really the 1050 Ti is a better deal considering how much hardware you get for the price. Please let us know how it goes. :)

Even more so if you're talking about 8K playback, the decoding alone will take a fair chunk of memory already.

[psyside]

Yes im getting the GTX1050 ti in few hours, cant wait!

Allwinner H6 SoC can decode 6K h265 30fps and 4k vp9 30fps: http://allwinnertech.com/index.php?c=product&a=index&id=66

Android boxes with that chip cost £50+. You can buy boxes that can hardware decode 4k 60fps in h265/vp9 for less money. There are no devices available that can hardware decode 8k h265/vp9 as far as i'm aware. Not surprising as there are no commercial 8k TVs available. VP9 won't be used for 8k for long anyway, they will use the upcoming AV1 codec instead in a few weeks once it is ratified.

[Asmodian]

There are no devices available that can hardware decode 8k h265/vp9 as far as i'm aware.

In this thread I showed obvious hardware decoding of 8K 60fps VP9 with a fairly old Titan X (Pascal). There are a lot of devices which can hardware decode 8K H.265 or VP9. :confused:

[psyside]

Oh yes there are :)

[Asmodian]

Very nice, I am glad it is working! :)

[psyside]

Very nice, I am glad it is working! :)

Its not working, it is butter smooth, i'm in awe, tbh a friend with 1030 said he can run the same videos with some buffer but we cant know since his net is only 30mbps, not sure if its the net or the card :)

Thanks so much for everything, highly appreciate it!

[psyside]

Also would add, users should not install the latest Nvidia 390.65 driver, me and 2 other had insane amount of problems with it, i mistakenly rma-ed a card cause of it, black screen, crappy playback and much more issues. I solve everything with 388.71

I know its different for everyone, but at least be aware.

[Asmodian]

How very strange. 390.65 finally fixed HDR support for me and has worked very well. :(

[psyside]

Well every system is different, i think it has something to do with windows version, (older ones have more issues AFAIK) but im not sure....:o

I would almost rma the second card as well, but in last moment i installed 388 and it worked, the same thing happen also on 2 other pcs of my friends when they tried to update, black screens or unable to finish the driver installation - really strange.

[Asmodian]

Hmm, that may be true. Actually, I would not be surprised if it has issues on Windows older than 1709, HDR support changed a lot in Windows too. I hope it doesn't continue to be an issue for you with future versions.

[psyside]

If i dont have HDR display, anything to benefit from| "madVR HDR" ? thanks :)

[Asmodian]

madVR is quite good at converting HDR for viewing on SDR displays.
