what can I do next to help get this resolved?

[DragonQ]

I don't know why nevcairiel don't want spend about 5 minutes to add h265 10bit hardware acceleration via CUVID in WinXP by implementing 100% working code in LAV Filters https://github.com/Nevcairiel/LAVFilters/issues/145 and then officially stop WinXP support in LAV Filters. All people using WinXP (I often see here in the bottom of posts too) will know i.e. 0.70.3 is last fully functional in WinXP version of LAV Filters and if they have (or buy) GM206-based videocard h265 10bit hardware acceleration via CUVID must work in their old sweet WinXP. I believe that's right.
PS. May be nevcairiel affraid National Security Agency (NSA) prohibit using WinXP to easier watch for people all over the world? ;)
I don't understand the problem. If you've written the patch but nevcairiel has refused the pull request then just host a fork with that patch applied. You and anyone else with Windows XP can use it, at least unless/until the underlying code gets rewritten.

Why don't you spend some of your free time to change the code so that it meets you personal requirements? LAV is open source, ffmpeg and libbluray also, so everyone can locally change the software. nev does not need to do anything because he also has a normal life like all of us... I think this is kind of unfair.

I i were nevcairiel i also would not waste my time to support Windows XP. XP is way deprecated and has many disadvantages - also for a multimedia platform.

And if you need to add workarounds, hacks, tweaks only for Windows XP, then this is not good for the code base

Thanks.

I believe while nevcairiel not stopped support WinXP he have to do some LITTLE (just insert some written by Aleksoid1978 strings of code) work to his LAV Filters to all people have more choice. I don't want to discuss with you disadvantages of Win7-10 in my case - if you want read my posts in this thread.
I have this patched decoder for a long time (so I'm personally not interested in this patch but we Russians usually take care about all world although many foreign people not understand how and why) and it work almost perfect in WinXP and I'm sure I'm not one on the planet Earth who need this (HW acceleration of h265 10bit i.e. from SATs in WinXP) feature, read i.e. fresh post here https://forum.doom9.org/showthread.php?p=1810680#post1810680
I just want all people in the world who like WinXP (especially SAT amateurs as I am) use ready fresh solution not compiling anything.

[strumf666]

Why don't you go pester M$ support, to update winxp so it will work with LAV filters as it is.

[rock]

hi VictorLS, maybe you could get this feature from unofficial build, like codec pack (K-Lite, Shark007).

[stax76]

Sorry but what is SAT?

[VictorLS]

stax76
SAT is satellite. Most of ~20 4K channels are being translated from SATs in h265 10bit format and we can watch them in WinXP only with patched LAV Video Decoder.

rock
I hope get new versions of LAV Filters from MPC-HC by clsid now https://forum.doom9.org/showthread.php?p=1812899#post1812899 (if vevcairiel wouldn't add this patch in LAV Filters in a future).

[stax76]

I hope your channels don't suck like where I live.

[VictorLS]

stax76
Most of 4K channels available (not encrypted) from SATs are demo (incl. Fashion 4K) now but I hope in a future watch 4K channels with good content.

clsid
I've taken files from x86 LAVFilters dir to KMPlayer in same manner as I do with patched by Aleksoid1978 files but h265 10bit file don't accelerated in WinXP - Active decoder avcodec in this case (
Same with mpchc_x86_1.7.13_20170717 version.
PS. h265 8bit are accelerated well as with non-patched decoder.

[clsid]

I can only test on Windows 7. I don't care much about XP and certainly not about kmplayer. Try with MPC-HC.

[VictorLS]

clsid
I've already written "Same with mpchc_x86_1.7.13_20170717 version." to mention cause in decocoder, not in your version MPC-HC.

Is there anything in LAV Filters that changed between LAVFilters-0.70.2-4 and LAVFilters-0.70.2-7 that would result in dropped frames and presentation glitches with madVR? When I installed LAVFilters-0.70.2-4 I get good playback with madVR but when I install LAVFilters-0.70.2-7 I get significant dropped frames and presentation glitches. Let me know what information I can provide to troubleshoot. Thanks.

[Asmodian]

I recently got a Creative AE-5 which supports 384 KHz audio modes (for some reason). However, when I enable any of them I don't get any audio from LAV Audio. Is this expected? I do get sound from other applications.

Win 10 Pro 1703, Zoom Player MAX v13.7.1, LAV Audio Decoder 0.70.2.

I do not consider this an issue, I am only reporting it. 32 bit, 192 KHz is fine for my use case. ;)

[LigH]

May depend on the audio output technology, and whether it allows drivers (or the "Wave Mapper") to upsample on their own, or requires provision of the audio in native sampling rate? ... Just guessing. In general, 384 kHz sounds a lot like "placebo for audiophiles" (similar to gold-plated digital cables) :sly:

[nevcairiel]

LAV just decodes the audio its given, it does not handle output or talking to the soundcard in any way - thats the job of the audio renderer.

[Asmodian]

I didn't even think to check the audio renderer. :o

Sure enough, after switching from "Default DirectSound Device" to "Speakers (Sound BlasterX AE-5)" I get audio even when set to 32 bit, 384 KHz. :)

[P.J]

Does Nvidia DSR have any effect in upscaling 1080p videos on 4k display?

[nevcairiel]

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

[el Filou]

Does Nvidia DSR have any effect in upscaling 1080p videos on 4k display?
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.

[VictorLS]

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.

[lvqcl]

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

https://github.com/mpc-hc/mpc-hc/commit/3e5afbc869f00f11d5b8349156185719814dbaf3

[VictorLS]

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 ;)

@nevcairiel

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.

[lvqcl]

for all these people with poor incomes

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

If it's not a great deal of work for you

clsid added (https://forum.doom9.org/showthread.php?p=1812899#post1812899) this patch to his build of MPC-HC and then VictorLS reported (https://forum.doom9.org/showthread.php?p=1813115#post1813115) that it doesn't work as expected. So probably it requires some debugging.

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.
So probably it requires some debugging.
May be you're right but I'm sure nevcairiel (if he'll wish) will workable implement that code from the first time.
@nevcairiel

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.

[rack04]

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

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.

[FDisk80]

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

[FDisk80]

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.

[nevcairiel]

The issue was that DXVA2 wasn't used at all, and that issue is resolved. If you're seeing anything else, its likely your setup.
There haven't been any changes other to how DXVA2 is started - which resulted in it not being used in a few rare cases - but once its setup it still behaves just like it did in 0.70.2 and before. So if you confirm that DXVA2 is actually in use, then there are no differences to before.

It is active.
For now changing to NVIDIA CUVID solves the issue completely.
I'm not sure what could be wrong with my setup. It worked fine with DXVA2 before I updated nvidia driver, LAV and madVR to latest versions.

[nevcairiel]

Well if you upgrade 3 components in one go, then isolating the problem to one particular component should be the first step, instead of randomly guessing what might be to blame. :)
The NVIDIA drivers also sometimes reset their power management on upgrades, it should be Adaptive at least, Optimimum Power is too aggressive in power savings. CUVID can work around that particular issue by forcing the GPU into max power mode (which is a sideeffect of using CUDA).

What determines audio sync? I've noticed for the past couple of weeks that the audio and video become out of sync using the latest madVR, LAV Filters, and MPC-BE. If I skip to a place in the video the audio gets back in sync with the video. I'm not experiencing dropped frames with madVR. Which program would set this sync? I'm viewing retail Blu-ray and DVD. Thanks.

[ryrynz]

I haven't experienced anything recently although I did about a week or so ago but I'm always updating.. Not sure if it was the media or something else but it appears it's gone/fixed now. Grab the latest nightly lav and Mpc-be.

Same here if I move the media player to another monitor/screen.

[nevcairiel]

Sync is generally provided by the timestamps and maintained by the audio and video renderers.

I have a problem since version: LAVFilters-0.70.2-10

DTS Bitstreaming results in very choppy playback, MadVR says suddenly clock derivation 30 - 50% and it's visibility dropping frames every second. Installing LAVFilters-0.70.2-8 or previous everything works fine and i get only 1 frame drop every few hours and clock derivation is again ok in MadVR OSD.

AC3 Bitstreaming hasn't this problem and works fine in current LAV too.

Using Nvidia 1060 via HDMI to AVR/TV.
