Topic: SVP works excellent, but lags badly on 8K or 4K 10-bit videos

Hi; I'm testing out SVP right now, and I'm really liking it. I have some questions though:

On 4K 10-bit videos (or 8K) (YouTube), I'm noticing that the video will lag immensely, even though CPU and GPU usage are low. Is there any way to fix this?
4K without 10-bit and 8K (if the original didn't have 10-bit) plays perfectly fine.

Also, is there any way to do force above 60 FPS on 60 FPS videos? I noticed that if a video's already 60 FPS, SVP just leaves it at 60 FPS.

Re: SVP works excellent, but lags badly on 8K or 4K 10-bit videos

To eliminate lags on 10-bit videos try to select another decoder.

To make SVP work to videos already 60 fps change value of setting frc.target.max.

Thanks, the second one worked!

The first one however, I use MPV, so I don't know how to change decoder
It feels strange, because when I try to play 4K/8K 10-bit, the FPS drops to 10 and gets stuck there. Is there some reason why it's always that value?
Again, it's barely using any of my CPU or GPU, so I think maybe there's some setting involved?

It starts off okay for like 1-2 seconds, and then hard locks at 10 FPS without even trying to push higher.

Do you know GPU has several blocks? I talk about decoding block. You can use GPU-Z to watch to load of each GPU block.
mpv has decoder settings. You can select decoder by option --vd=<...>

Re: SVP works excellent, but lags badly on 8K or 4K 10-bit videos

Thank you for your reply

I'm familiar but certainly not an expert with this sort of thing, so if you could tell me what to do for mpv, that would be great.
I think your Wiki said to use NVIDIA CUVID? How can I do that, exactly?

As for 10-bit video, it's basically every one on YouTube. Any 4K/8K video that has HDR 10-bit will get locked to 10 FPS when I try to pass it through SVP to mpv.
However, if I play the video at 4K (without 10-bit) OR 1440p (with 10-bit), it will work fine.

Re: SVP works excellent, but lags badly on 8K or 4K 10-bit videos

10-bit 4K in mpv requires rather high-end CPU...

1. you can turn off 10-bit processing in SVP itself - it will convert in to 8-bit internally (App. settings -> Add. options -> Allow output in 10-bit color depth)
2. HDR videos on YoutTube are encoded with VP9 codec. Not all video cards supports 10-bit VP9 in hardware. For example, 1050/1060/1070 don't.
3. 8K is definitely too much for now...

> I think your Wiki said to use NVIDIA CUVID? How can I do that, exactly?

put "hwdec=nvdec-copy" into mpv.conf

Re: SVP works excellent, but lags badly on 8K or 4K 10-bit videos

@Chainik

Yeah, that's the thing; I want to try to process 4K/8K 10-bit video because I'm fairly sure my CPU and GPU can handle it, but something may be prohibiting it from doing so.

So far, 4K30 HDR, 4K60 SDR, and 8K30 SDR work perfectly fine (as well as all other lower options) rendering to both 4K60 and 1440p120 without any frame drops.
(In the case of a 60 FPS source, I forced the video to render via the setting that @MAG79 mentioned.)

If I try to process any higher quality video, it seems like the system doesn't even want to try.
The video caps off at a constant frame rate of 10 FPS; not a variable one of whatever it manages to render. That is what I find to be strange.
Even if it can't render the video properly, it should still be getting at least like, 30 FPS on 4K HDR (perhaps with frame drops), based on what I can already manage.

Is there any sort of setting in SVP or mpv that might be causing the video to cap off at 10 FPS?

Also, I tried pasting your setting into mpv.conf. It didn't seem to do anything. I also tried the vd setting that @MAG79 mentioned with NVIDIA CUVID VP9. Same deal.
