madVR - high quality video renderer (GPU assisted)

[ADude]

Can any part of the new feature set, be used to prevent scaling when the video size is a few pixels smaller than the display size?

For example, videos of 1916 x 1076 or 1912 x 1072 - which for some reason are used by some commercial download sites. This scaling of less than 1% larger, is quite GPU intensive and results would be far better with no scaling. But it would have to still be reported to the player as 1920x1080 otherwise the video drivers would scale (since that scaling cannot be disabled due to the PC being used for other purposed besides media players).

Thanks!

there is an option called "disable scaling if image size changes by only:"

that should do that. and media player could always do things like that like MPC HC video frame- > normal

madshi,

I've tried using touch window from outside and stretch to window but both have no effect, the osd shows touch window from inside and the black bars remain visible. I'm using the latest 64bit nightly build, zooming the bars away works but zooms in and cuts off the subtitles which of course you don't want.

Here is a sample, re-encoded (cropped and re-sized to 1920*1080) that shows the result I'm after, use stretch to window.

Not an ideal solution but works as expected, It's not a big deal but would be handy if you could add the ability to simply crop the black bars away completely when you have time.

Thanks.

Hey,

I use JRiver Media Center 20 with Red October HQ mode, so madVR.

I have a weird issue with display mode changer in that it just kills the video driver (NVIDIA GTX 750 Ti) which requires a reboot to fix.

I can use the NVIDIA Control Panel to switch to the resolutions I'm using in display mode, so it appears to be a madVR issue (or JRiver Media Center).

I'm running Window 10 x64.

On this subject, could someone help me achieve my goal: my display's native resolution is 1024x768 (it's a Panasonic Pro series panel) so I would like to get the best experience.

I also use Amazon Prime Video from this PC and setting the desktop resolution to 1024x768 results in big bars top and bottom in the Amazon video player, so I have it set to 1366x768. I'm told I should get madVR to only switch to 1024x768, but this results in a small, square video in the middle of the screen when using JRiver.

Can someone help me get it setup properly?

Thanks!

Hi Madshi!

I updated Seven to Windows 10 (not a clean installation but using Windows mode) and I got a strange issue using MadVR with MPC-HC and the same settings.

When the player switches to exclusive mode seems like that the resolution changes to 60 Hz form 25 because the CRT projector goes to the appropriated memory bank; if I leave the exclusive mode visualizing the menu (or the seek bar, ecc.) the CRT goes back to the 50 Hz memory back.

Unchecking the Exclusive Mode from MadVR options everything goes smooth and the visualization remains in the same memory bank where started.

I didn't change any settings in MPC-HC and MadVr, and the automatic changes in the Fullscreen option menu of MPC-HC is unchecked.

Thank for your reply!

That's not in the release notes for any version, is that part of the new version 89, or did it arrive earlier ?

added in 0.89 it just a part of zoom control.

The feature "restore original display mode when media player leaves fullscreen" is not working for me with MPC-HC + LAV codecs (x64). The refresh rate only changes on playback stop. If I manually leave fullscreen during playback or pause, the refresh rate stays on that of the movie and won't change to the original ever, unless I do it via NVIDIA Control panel myself.

I got this exact same problem after updating to Windows 10. I "fixed" it by setting prepresented frames to 3 (4 or higher causes it to break again). Even though 3 is stupidly low, I don't get glitches or dropped frames, and smooth motion seems to be working as intended.

In other news, updating to windows 10 has magically fixed my crashes when turning on error diffusion and nnedi3. Yay!

In windows 10 nnedi3 can't be used(for now)
So if u select nnedi3,instead Jinc is used.
Check OSD (Ctrl+J) for active scaler.

Edit:I totally forgot about AMD

Nope. It's being used. ATI on windows 10 works just fine for nnedi3.

NNEDI3 image doubling does not work on all ATI/AMD with Windows 10. I Haven't been able to get NNEDI3 to work with my AMD R7 265 since I updated to Windows 10. Worked just fine with Windows 8.1 though. I would be interested to know if anyone with one of the newer re-branded Pitcairn GPU's are having similar issues as I am having?

nnedi3 works totally fine on my r9 270.
nvidia has broken nnedi3 with there driver on windows 10

I see you have the same graphics card as I do. Are you experiencing similar problems with Windows 10?

d3d11 was quite broken but i haven't used it in a while. so yes.

i had to use special present queues to make d3d11 work without tearing.

Now I ask stupidly. Is it a Windows 10 problem or is it AMD? Is there anything I can do to make them aware of the problem. Or are they aware of it?

[aufkrawall]

I'd just assume that there are plenty of bugs both in AMD & NV drivers on Windows 10 (maybe AMD is a bit worse after reading here).
With Maxwell on Windows 10 and 353.49 driver, it seems best to use D3D9 renderer, D3D11 gives me sometimes weird judder when opening a new video without closing MPC HC first.

i guess the problem is d3d11. my 960 makes problems too.

A very small bug in madvr:

In the settings dialog, under processing, image enhancements, LumaSharpen, the value for clamp is 0.035 after a fresh install. If you push the restore defaults button on the image enhancements page, the value changes to 0.010. So either the restore defaults button should make clamp 0.035, or the fresh settings should have the value as 0.010.

Got it working after updating Nvidia Drivers to 355.82, the issue was or seems to have been with the set windows installed. Not sure how it was over-ridden, but I ended up with a copy from Windows update.
