Any image processing in LAV Video happens on the CPU. As such any advanced techniques are too expensive performance wise. The random or ordered dithering methods are as good as they can be, given the constraints.
If you convert a high-bitdepth image to ordinary 8-bit before the renderer, there will always be a loss, this cannot be avoided.

Ok. Well.
Now I have to hope that AMD will support AMD FLUID Motion with 10bits in the near future...
Is a i7 7700K that limited for a better dithering in Lavvideo?
I mean right now, it's doing nothing and is letting madvr do all the heavy lifting with the GPU.

nevcariel, do you think there'll be a new supported release by the end of the year? Is there lots of worthy stuff in the nightlies?

Hopefully I get some more time over the holidays to finish some things and make a release then.

Bad news from Microsoft: W10 Fall Creators Update removes HEVC codec (which is required to play e.g. Netflix 4K HDR); you could purchase it in the store if you need it ...

I don't know about Netflix. I don't know which combo of hardware and software it requires. Is it bound to MS Media Foundation decoders? Or would LAV Filters be a supported free alternative?

Except its free and not for purchase.
https://www.microsoft.com/en-us/stor...n/9n4wgh0z6vhq

But nothing can replace that, since only it will support the required DRM for Netflix etc.

On that note, as of today there is also a second one for Vorbis/Theora, called "Web Media Extension"

YADIF deinterlacing is not working when DXVA is enabled as hardware decoder (native or copy-back doesn't matter). Is this expected?
- Using the latest nightly (0.70.2.80)
- 1080ti with 385.69
- tried nVidia settings deinterlacing inverse telecine checked on and off, no change.

EDIT: copy-back works!

Yadif is a pure software deinterlacer. You cannot make DXVA deinterlace with Yadif in the GPU.

Oh, wait, you expected Yadif to deinterlace after pure hardware decoding ... sorry, it is late already.

yup, I am assuming after doing hardware decoding, software YADIF should be able to kick in. But it doesn't.

At least the way it is presented in the UI, I was expecting it to work because I can select software deinterlacing after enabling hardware decoding.

Is it not supposed to work?

With Copy-Back YADIF should be working fine. With Native it cannot work.

The reason options dont grey out is simple: Not every clip can be hardware decoded, and for those all software options always apply.

you are absolutely right (why wouldn't you )

copy back works fine. Thank you for the quick follow-up.

Thanks. I didn't want to put pressure on you in any way. Take all the time needed.

Hi, can anyone tell me if FSE (full screen exclusive) is required for Full frame packed MVC playback using AMD cards, I cant get it to work without using MADVR with FSE turned on.

This is not related to LAV Filters, it only performs decoding.

Do not forget about me ...

There are no plans to handle those.
