Nev, please have a look-

what can I do next to help get this resolved?

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

This contains that patch:

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.p...80#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.

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.

I hope get new versions of LAV Filters from MPC-HC by clsid now https://forum.doom9.org/showthread.p...99#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.

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.

I noticed a color distortion when converting YCgCo to RGB48. Conversion to RGB32 works fine.

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.

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)

[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.

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.

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