Internal processing can "undo" much of the benefit of madVR, especially if any scaling is being done.

still massive dropping frames

Hi Guys,
I was thinkin' that my old GTX 970 was not enought to reproduce 4K HEVC files @60fps but this is not the case.

I've created a new HTPC with NVIDIA RTX 2070, cpu i7 7700T and a new asus mobo pci express 3x. Win 10.

Latest Nvidia drivers. Focus assist deactivated.

Still have massive (very massive)drop frames with those 60fps files ... My queue is always empty ...also with low rendering times.

The attached pictures are taken during reproduction...

MadVR is the latest with V39 beta build installed.

The 60fps files are on an SSD drive.

Some days ago I've tested this also on a Pc of a friend that has a 1070ti and dropping frames with HEVC 60fps files still there ...

Please give some help.

Thank you

In the lav filter image attached to previous post there is: hardware accelerator =none.

Maybe this is the problem?
Maybe I'm not using nvidia hardware hevc decoder?

You need to upload the pictures to an image site, as it takes a long time to get approved on site.

You're probably right. HEVC requires a lot of CPU power to decode directly because of the complexity of the compression algorithms.

I agree, a 7700T cannot decode 4K HEVC in real time, using software decoding.

Try changing it to D3D11 or DXV2 (copy-back).

Hi guys, the queue is empty with D3D11 actived!
Look at the images...







I've already tried DXV2 copy back but still have the same amound of droped frames...

If I'm not using the hardware decoder of my RTX 2070 ...how to activate it??

Set the hardware device to "Automatic (Native)" not the RTX 2070.

It has also been advised to use enable automatic fullscreen exclusive mode with the RTX cards.

If I remember well at the biginnin' lav decoder was set "automatic native" but the massive drop frames still there.
This evening I'll verify it again

I'll try also FSE but I can't imagine that is this the reason of my empty queue ...

Not checked but ... Billy lin (look at the image) is HEVC for sure.

Can someone of you post a capture of his LAV video decoder panel?
I want to see if your LAV reports something different of mine ...

thanks

It is because the graphics card is choking, others have mentioned issues unless in FSE with the new cards, also I see no mention of HDR on the OSD.

Try HDR passthrough as well before you use the newer HDR options (which you have switched off in Trade for Performance mostly) and work from there, but do what the others have said first.

you can check the file with properties in mpc-hc.

your lav filter setting are showing software decoding and you have a select a hardware decoder so this looks like an incompatible file format.

Checked now. It's HEVC, mkw and HDR file. You can download it there....

I'm pretty sure this is the reason of my problem .... with every option under LAV decoder checked I can't see anything different on: hardware accellation = none.

Any idea to activate it?
Any option under nvidia control panel?

there are many types of HEVC not all a hardware decodable.

check the demo you linked me first this file has hardware compatibility.

Showing proper aspect ratio/zoom on Ultrawide Monitor for content that changes Aspect

Hey all,
So hopefully this is a simple question to answer, but I've been fighting this for some time and I don't seem to be any closer to solving it.
I have a 21:9 Ultrawide monitor. It works great watching films that are shot in CinemaScope.
Some films (mostly Nolan films) will change aspect ratio from 16:9 (for IMAX shots, for example) and then for normal shots will be 21:9. I'm trying to figure out a way to show all content with as few bars as possible. This would mean:

Zooming 21:9 shots to crop the letterboxes
NOT Zooming the 16:9 footage and showing pillarboxes.

I can't seem to get MadVR to do this. I've tried dozens of combinations of settings and the best I can do is have it either zoomed to 21:9 all the time (losing picture during 16:9 shots) or just showing pillarboxes ALL the time and then also showing letterboxes during 21:9 shots.

Here are the settings I have:
*Disable scaling if image size changes... Tried all different settings, currently on 3 lines or less

* Move Subtitles into active area

* Automatically Detect hard coded black bars (yes)

* if black bars change quickly ... don't switch more than every 5 seconds (tried disabling this too).

* Notify ... immediately after every change

* Zoom small black bars away

* crop black bars

With these settings, nothing seems to be happening at all. Dunkirk will just play in 16:9 with pillar boxes and letterboxes in 21:9 scenes.
If I enable:
* If there are big black bars... zoom the bars away completely

Then I get the entire movie at 21:9 with no boxes anywhere, because it's zooming them away... but then I'm losing a chunk of the frame.

Basically - MadVR either lets me have no boxes (pillar or letter) or just leaves it alone. This would work if I had a 16:9 monitor and I was playing 16:9 content that switched to 21:9 because the bigger frame is my native aspect ratio, but when the native ratio is wider than the film ratio, it seems like this causes issues.
For now, I have to flip in and out of zoom levels with keyboard shortcuts, but this sucks. Am I screwed? Is there no way to fix this?

change the hardware decoder from dxva native or d3d11 to DXVA copyback.

blackbar detection is run on the CPU and with a native decoder the CPU never sees the image.

this is not well documented so what could you do.
