It doesn't work. MadVR says deinterlacing is on, but it is not working. Well, madVR deinterlacing doesn't seem to work at all actually.

Is that the old issue with DVB Viewer? I thought that had been fixed. (Edit: @nevcairiel yes, my bad, I think it was ProgDVB)
I just tested again with an interlaced video in MPC-HC and MediaPortal and with those apps it works.

[nevcairiel]

If it was DVB Viewer, I probably would've heard, since I'm in contact with the devs directly on occasion. Probably some other DVB application.

you are not by accident using film mode?

[el Filou]

Recently I have been watching old motorsport races from YouTube, and I encountered an unusual problem: the uploader had encoded them as progressive video (720x480 29.970 fps), but the images were still visually interlaced. So I tried setting Deinterlacing Mode in LAV to Forced for madVR to treat them as interlaced and it did but I was having the same issue as mzso: madVR was showing deinterlacing on and output was 60 fps, but I could still see the combing artifacts (film mode wasn't on). To solve it I had to uncheck "Use inverse telecine" in NVIDIA's control panel.
Maybe something like that is happening with the DVB app mzso is using?
I have no idea why that happened and how I would achieve the same with AMD as you can't disable IVTC anymore in their control panel.

I'm using SmartDVB.
I faintly remember having a similar problem, which was fixed on madVR's side. I remember it with SmartDVB (but I did use progDVB years ago though, so I'm not certain.)
Doesn't PDVB only have madVR support since not so long ago?

Since I got ample amount of combing I'm quite sure neither mode was active.

[huhn]

with film mode on interlaced content you can only get combing and nothing else it only works on telecine content.

@el Filou
Thanks for reply but I've asked is there any difference between HW acceleration method in case of SAT stream corruption? Or all you've mentioned is equal in your case?
@mzso
Btw I always turn off Inverse Telecine immediately after install nVIDIA's drivers to avoid deinterlacing issues while watching SD channels from SATs with excellent donateware SmartDVB.

Well, all I can say is that madVR's set to force video mode. And even if I cycle between modes manually the video doesn't change.

@mzso Try to go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000\UMD\DXVA in Registry Editor and change 3to2Pulldown (Binary) to 30 00 00 00 instead of 31 00 00 00 , and 3to2Pulldown_DEF (String) to 0 instead of 1.
I can't guarantee this will work, but worth a try.
(I'm using Radeon Software 20.11.2 WHQL and that is the exact key)

Wrt handling DVB streams with corruption, on my very old system native DXVA is a bit better than DXVA copyback or CUVID (less stutter). Both are much better than software decoding. But I only have H.264 channels, not H.265.

@el Filou
Thanks. I've bought GTX750v2 on GM206 special with 1 GB (not 2 GB) videomemory (~100$) to prove to myself 1 GB enough for fluent 4K playing (it's really enough 1 GB videomemory) and it was fluent with EVR and even CUVID but when HDR (HLG) appears EVR (not EVR-CP) give not right colors and madVR requires more than 1 GB videomemory but MPC-BE's MPC-VR shows even Gemini Man H265 4K 60fps sample absolutely fluently with two external shaders. And for 4:2:0 H264 1920x1080i50 (incl. 4:2:2) I don't see difference between software (~30% CPU load) and CUVID or DXVA (native&copy-back) hardware (~10% CPU load) acceleration with my old AthlonII x3 460 - ideally fluent playing in all cases (if CPU isn't loaded with other hard tasks).

MPC-VR is indeed a bit conservative, compared to madVR, and helped me playing 4K UHD videos on a GT 450 with only 1 GB VRAM where madVR demanded better hardware.

@nevcairiel
Thank you Nev! Fixed in LAVFilters_v0.74.1-108

UPDATE: Excuse me please for making wrong conclusion. I'm confused because the problem #35 still appears...

Hi Nev,

Two questions:

1) Does nightly 114 fix the bd menus issue with d3d11 native that we discussed in the jRiver forums?
2) I have LAV and LAV64 installed in the plugins folders of jRiver to have only one install of LAV in the system. How do you get the files only for the nightly builds, in order to avoid having to install LAV with the exe and create a new LAV install?

Thanks!

A zip package of the files alone would be great, simply extract the zip to the existing folder and over-write existing files seems like an easy thing to accomplish.

Note: This is what I do and haven't had any issues and things appear to work, please make sure you're confident this is safe for you, otherwise please keep asking for a zip or 7z archive and ignore my post

I haven't used the installer in a while so I don't recall if you can point the installer to your existing folder and over-write existing install but most apps have this functionality.

What I have been doing is using an extraction tool and extracting the contents of the latest beta builds to a temp folder, then moving the updated files into my existing folder.

The tool I use is Universal Extractor 2:
More Info: https://bioruebe.com/dev/uniextract/
Zip Download: https://github.com/Bioruebe/UniExtract2/releases

UE2 extracts the important files to \x86 & \x64 folders, the other stuff is for the installer and can be deleted.

I used a stable release portable version install to make sure I continued to follow the same layout - this is what I grab from the relevant x86/x64 folders, this continues to match my original portable install, the installer may do things different so be careful:
\LAV\ (13 files)
.................. avformat-lav-58.dll
.................. avfilter-lav-7.dll
.................. avcodec-lav-58.dll
.................. avresample-lav-4.dll
.................. swscale-lav-5.dll
.................. LAVAudio.ax
.................. avutil-lav-56.dll
.................. libbluray.dll
.................. LAVVideo.ax
.................. IntelQuickSyncDecoder.dll
.................. LAVSplitter.ax
.................. LAVFilters.Dependencies.manifest
.................. COPYING

Note: The COPYING file was installed with the original portable install so I continue to move it along with the other 12 files, it is likely not needed but it's small and I want to stay consistant.

It took longer to write this versus running UE2 on the latest LAV beta and moving the new files over.

I'm confident if this is a really stupid way to update LAV someone will chime in (I Hope) but it has continued to work for me, LAV is being used with MPC-BE portable and I see the player using the external LAV filters.

HTH & good luck

Hi M.Scott, thanks for this, I’ll wait to hear from Nev but it sounds like an easy solution if there is no zip available for nighties.

[wanezhiling]

I bought a new laptop with i5-11300H (Iris Xe Graphics)
Driver: latest 27.20.100.9316 (3/3/2021)
LAVFilters-0.74.1-114

LAV AV1 dxva2 decoder is active only in DXVA Checker, not working with madVR or MPC-VR
.


ps: tested with many 4k/8k av1 clips(8-bit,10-bit), same result
pps: lav d3d11 decoder, same result

I do like M.Scott in many years (at first I was using Inno Setup Unpacker Editor but some years ago begin to use latest UniExtract). After extraction I copy all files inside x86 folder to my favorite player KMPlayer and to LAVFilters folder in latest release of MPC-HC (and x64 to LAVFilters64) and register LAV...ax's by myself for using in donateware app SmartDVB to watch SAT channels with latest LAV Filters.

Thanks for information - while Intel Xe isn't supported by LAV Video Decoder (AV1 and 4:2:2 4:4:4 hardware acceleration) I even don't think about purchasing it (when it'll support h266 VVC hardware acceleration may be will necessary for me tough in case of h266 VVC will become new SAT encoding standard after h265 HEVC) so let us know if AV1 hardware acceleration will work in ordinary players like MPC-HC(BE), please.

[Manni]

Uniextract works great and nightly 114 resolves the issue with BD menus when using D3D11 native. Thanks for fixing this.

D3d11 decoding should work with this driver and LAV, I've tried it on my Iris Xe - no problem. I believe DXVA2 AV1 has been disabled/deprecated in newest drivers.
