I noticed two issues with the current nightly:
-YADIF doesn't work for VC-1 interlaced (without software deinterlacing, LAV reports interlaced content properly to renderer).
-When changing the YADIF setting when LAV config is opened via MPC HC filter list, it makes the player invisibly hang in background after closing.

For people who still like WinXP - last working version of subj is LAVFilters-0.70.2-16 and it's a pity (as all non-modified LAV Video Decoders) it can't hardware decode H265 10bit via CUVID on nVIDIA's GM206-based videocards - it seems nevcairiel too hard understand how it was made working (but it's just few strings of code).
Next installer LAVFilters-0.70.2-29.exe says "This program does not support the version of Windows your computer is running."
Best regards.

Btw: What's the reason for the brief corruption after seeking in HEVC 10 bit video? It happens with both software and hardware decoding, but not in the Windows 10 video app.

Container (TS?)? Sample?

I could maybe hide the frames (like h264 does) if that makes you feel better? It would still start decoding a "proper" image at the same spot as it does now though.

MPEG-TS is generally not a format you should expect "perfect" seeking on, because the format itself has basically no seeking support. Even finding the appropriate timecode in the file is already a slow process, and with broadcast streams can even be really annoying (ie. with wrap-around).

That should be fixed.

I can't reproduce that. All settings changes are really quite equal, change the value, save it. It doesn't do anything special for those settings.

You nailed it, both tested files have TS container. Thanks.

I can always provoke it by turning YADIF off in a paused video and then close MPC HC.

Seems like an odd way to do things, but I've found a work-around for the issue.

Hey, great work on LAV filters. I did have a quick question though.

Using a youtube clip downloader (https://yd.3dyd.com/), I downloaded a 60fps 4K clip on youtube (https://www.youtube.com/watch?v=ArPP6_QXqyQ) and watched it with the latest LAV + madvr available using D3D11 hardware decoding. It worked perfectly, lav video reporting that the active decoder is D3D11 native and madvr OSD showing the DXVA11 flag. I also tried to download another 60fps 4K clip, but with HDR (https://www.youtube.com/watch?v=GTGm7mye-_4). The file isn't hardware decoded, LAV video showing that avcodec is active. Both files are straight from youtube so encoded with VP9.

Is this an expected behaviour ?

Thanks !

For HDR Youtube provides VP9 10 bit - for SDR only 8 bit. 1070 cannot decode VP9 10 bit. So if you downloaded the VP9 10 bit stream that should be the reason.

Sorry for shameless self-quote – and yes, VPx is another issue, in relation to MPEG specified formats.

OK thanks, I knew there was a bitdepth difference, but couldn't find the exact decoding capabilities of the 1070.

Quick question: updating from nightly 45 to 49 and later, I loose DXVA11 native decoding, the active decoder now being D3D11 cb direct instead of D3D11 native. Is this normal ?

Did you select the active decoder instead of leaving it on automatic?

I did leave it on automatic. A settings reset solved it. Thanks

madshi hasn't implemented deinterlacing for D3D11 DXVA yet.

In build 0.70.2.66-git I have made the observation that in video filters if you select DXVA2 (native), it will display the expected NV12, 8 bit, 4:2:0 (DXVA2).

However, if you then change it to None, it continues to display NV12, 8 bit, 4:2:0 (DXVA2) even though software decoding should be in use at this point.

If you change it to DXVA2 (copy-back), it will display NV12, 8 bit, 4:2:0.

Then changing it to None, it displays NV12, 8 bit, 4:2:0.

Repeating the process where you go back to DXVA2 (native) and then None, None once again holds on to (DXVA2).

It doesn't change without re-starting playback.

You are right. It is not enough to just stop playback, you have to quit out of the player entirely and restart it.

In MPC-HC there is a hotkey to restart. ( ctrl + e ?)
