LAV Filters - DirectShow Media Splitter and Decoders

[nevcairiel]

LAV just decodes the video to its native resolution, anything that happens beyond that is not quite related to LAV Video.

It would make the video renderer upscale the 1080p video to more than 2160p, then the GPU would downscale it to your display's 2160p.
Juste a waste of GPU power when applying it to video playback IMHO.

nevcairiel, does not being registered in WinXP LAV Filters 0.70.2.1 from LAVFilters folder of 32bit MPC-HC 1.7.13.60 mean you stop support WinXP without h265 10bit patch?

[nevcairiel]

How mpc-hc builds their copy of LAV is unrelated to what I do. But I still have no plans to apply any such hacks, and as stated before LAV will quite likely also drop XP support in the next release.

MPC-HC doesn't support WinXP anymore, so their version of LAVFilters doesn't support it too.

nevcairiel, I still hope you'll change your opinion and will implement h265 10bit 'hack' in your LAV Filters before you drop XP support and I (and many other SAT amateurs who use WinXP with GM206-based videocards) will use that last pre-release version of LAV Filters and will remember you with good words

XP is dead, move on. EOD.

Just wanted to bump this post as I can reliably reproduce this between LAVFilters-0.70.2-4 and LAVFilters-0.70.2-7.

Trying to play this file using DXVA2 (copy-back) results in dropped frames and presentation glitches in madVR. Works fine with NVIDIA CUVID.

Just see it as a last minute favor, before abandoning for good WinXP support, for all these people with poor incomes or great peculiarity who insist on that OS.

If it's not a great deal of work for you, it will be the last time involving with that Windows version.

Poor people that want to watch 4K 10bit satellite video?

clsid added this patch to his build of MPC-HC and then VictorLS reported that it doesn't work as expected. So probably it requires some debugging.

That should hopefully be resolved.

If say more exact - people (mostly SAT amateurs) that don't want spend any extra money (for newer then WinXP version of Windows -> Hardware -> unlimited Internet -> Antivirus ->... -> World)) to achieve great results (if it's achievable at all) - Aleksoid1978 proves that h265 10bit hardware acceleration via CUVID works quite well in WinXP with this https://github.com/Nevcairiel/LAVFilters/issues/145 patch code and he hasn't WinXP and GM206-based videocard as clsid too). So most of work was done.

May be you're right but I'm sure nevcairiel (if he'll wish) will workable implement that code from the first time.

Thank you for support my idea - I believe it's so logical too so there isn't any risk - if some will be wrong people always can use pre-last WinXP version of LAV Filters.
Besides, nevcairiel has implemented h265 10bit hardware acceleration via CUVID and switching off DXVA processing (to remove artifacts on some streams) for Win7 and newer I'm talking about in last year but don't want implement for WinXP - it's not logical on my own.

Appears to be fixed in LAVFilters-0.70.2-8. Thanks!

Can confirm this.

I thought it was an issue after updating the nvidia drivers.

[nevcairiel]

This issue was not related to drivers and has already been resolved in more recent versions of LAV.

Yes. I see, DXVA was fixed in latest version. Awesome!

I'm not sure that it was completely fixed.
Was watching GOT last night and that small freeze happened again. But it was much shorter than before. About 1 or 2 seconds instead of 4 or 5 seconds like before.

- Windows 10 x64 v10.0.15063
- nVidia v385.12
- MPC-BE (64-bit) v1.5.1 (build 2363)
- madVR v0.91.11 [fullscreen exclusive mode, 1080p @23.976hz]
- LAV v0.70.2.12 [DVXA2 (copy-back)] [10-bit P010]

Tried with NVIDIA CUVID and didn't see that small freeze.
