Hi Guys,

Please forgive me if this has already been covered in a previous post but I need advice in some of MadVR features involving those who have a 2.39:1 scope screen with a projector.

I have recently changed my 16.9 setup to a 2.39:1 setup and built a new screen. Most of my movies (99%) that I watch on this setup are wide screen format and I use my JVC projector to zoom the top and bottom black bars away and fill the screen with the movie.

I notice that madVR has functions that may assistance with this setup under screen config and zoom control... Can someone with a similar setup who are using these features or someone who knows about these features and believe this may be helpful please assist me and give me some tips...

Also there is apparently a way to overcome the multi format movies (ie Nolan movies) what is the setting for that please?

Thanks I advance for all your help..

 You need to be using DXVA2 copy-back hardware decoding in LAV Video for black bar detection and zoom control to work.

Try these settings as a starting point:



You may have to adjust always shift the image. I'm not sure. The same can be said for keep bars visible if they contain subtitles.

I don't have a projector to test, so I can't confirm with certainty that these settings will work.

I think the one setting where it says, pick one zoom factor that doesn't lose any content is probably the one that is used in his situation.

[Warner306]

That could work. The other option should handle titles like The Dark Knight, that switch aspects ratios throughout the video. You may want to remove all black bars in this case.

Find the drive or folder on your server computer that contains your media:

Right-click -> Properties -> Sharing -> Advanced Sharing.. -> Share this folder

Disable password protected sharing (I'm assuming this is how you shared things previously and the April update will enable it again):

Control Panel -> Network and Internet -> Network and Sharing Center -> Advanced sharing settings

All Networks -> Password protected sharing -> turn off password protected sharing

Note: Due to potential network vulnerabilities, Microsoft advises against disabling password protected sharing. When password protected sharing is enabled, Kodi requires the login credentials of the server computer (username and password).

On your server computer, write down the SMB network paths:

Right-click -> Properties -> Sharing

The "Sharing" tab will show the full path to the drive or folder with your media:

e.g. \\WARNER-PC\Movies

In Kodi:

Files -> Source -> Edit source

Enter the network path you wrote down from the "Sharing" tab  and select "OK":

e.g. smb:\\WARNER-PC\Movies

Thank you.. I actually just seen this now lol
. Sorry about that.. I will give a go tonight after work.. I reverted back to a previous Windows 10 version do you think it's worth upgrading it to the latest version again then try this out.? Thanks..

[mkohman]

@Tamuro, this is exactly what I did too [emoji6]

 Did you try my fix for SMB sharing? Your issue shouldn't be that hard to fix if nothing is wrong with DSPlayer.

There is also this: https://www.tenforums.com/network-sharin...grade.html

And this video should be watched: https://www.youtube.com/watch?v=uNeo7O6ImAo

The second video is very similar to the instructions I provided but includes some additional steps to look for.

Apologies again I have just seen this post.. Haven't been on this forum for a while.. Thank you so much.. I will definitely try this out [emoji106]

How to Configure a Display and GPU for a HTPC

The following instructions use the Nvidia Control Panel as the example hardware but should transfer directly to AMD and Intel.

Configuring Your Display

Setting correct video levels is the main concern on the display side. PC's operate in RGB 0-255, while most video content is Y'CbCr 16-235, and 16-235 is what most displays will be expecting. The majority will be configuring their display for PC levels, but it is possible to send video levels depending on how you configure madVR and the GPU.

In most cases, setting the video levels or color space to Auto is recommended to allow the display to determine how to best handle the input signal with the correct conversion. As shown below, if you need to force a specific output mode, this setting is described differently by display manufacturers.

Typical PC Configuration – Most common and recommended

(madVR) PC levels (0-255) -> (GPU) Full Range RGB 0-255 -> (Display) Output as RGB 0-255

The correct setting is Full Range:

• LG: Black Level - High
  
• Samsung: HDMI Black Level - Normal
  
• Sony: HDMI video range - Full
  
• Vizio: Color Space - RGB
  
• Panasonic: Black Level - Full
  
• TCL: Autodetect/Forced PC Mode - Set HDMI mode to HDMI 2.0
  
• JVC: Input Level - Enhanced
  
• Epson: HDMI Video Range - Expanded
  
• Optoma: Color Space - RGB(0-255)
  
• BenQ: HDMI Format - PC Signal
  
• Pioneer: Video - RGB0-255 
  

Alternative Configuration – For displays not able to handle full range signals

(madVR) TV levels (16-235) -> (Kodi) Use limited color range (16-235) -> (GPU) Full Range RGB 0-255 -> (Display) Output as RGB 16-235

The correct setting is Limited Range:

• LG: Black Level - Low
  
• Samsung: HDMI Black Level - Low
  
• Sony: HDMI video range - Limited
  
• Vizio: Color Space - YCbCr
  
• Panasonic: Black Level - Normal
  
• TCL: Autodetect/Forced PC Mode - Set HDMI mode to HDMI 2.0
  
• JVC: Input Level - Standard
  
• Epson: HDMI Video Range - Normal
  
• Optoma: Color Space - RGB(16-235)
  
• BenQ: HDMI Format - Video Signal
  
• Pioneer: Video - RGB16-235 
  

Last Configuration – Correct desktop with a display not able to handle full range signals

(madVR) PC levels (0-255) -> (GPU) Limited Range RGB 16-235 -> (Display) Output as RGB 16-235

The last option is not recommended because the range is converted by the GPU. For those choosing this path, the display should be configured the same as above: Limited Range.

Note: Sending RGB (full or limited) to the display may not work well in some special circumstances. For example, some displays have problems receiving RGB inputs with HDR metadata (like some JVC projectors) and must operate in YCbCr instead of RGB. If you are getting strange tints to the image, this could be you.

A warning should also be made about using PC or game mode. Such a setting is often necessary for 4:4:4 output, but typically comes with limitations for video playback. This can include an inability to switch refresh rates and poor color representation due to differences in HDR output or lower color volume. The LG OLED is an example of a display with inferior color volume in PC mode compared to other video modes.

After configuring the display, it is a good idea to test for black and white clipping with test patterns like these ones (under Basic Settings) and these two clips. This is one of the most critical points of set up for having a correct grayscale. Not all displays will behave the same with the same configuration depending on how it interprets and converts the signal.

Configuring Your GPU – Refresh Rate, Color Format and Bit Depth



The desktop color settings can be a bit confusing. The correct output format is almost always RGB. You don't want to destroy the work done by madVR by converting from RGB to YCbCr before output.

The desktop should operate at 60 Hz, while allowing the media player to change to other refresh rates when necessary.

And the desktop resolution should always match the native resolution of your display (1920 x 1080p or 3840 x 2160p) to ensure content is being upscaled in good quality by madVR. 

Discussion from madshi on RGB vs. YCbCr

HDR and WCG: This checkbox is not found in the GPU control panel but affects the desktop. Found under System -> Display, it should be disabled by default in Windows 10. madVR does not rely on Windows OS HDR and will switch between SDR and HDR when necessary (using Nvidia & AMD APIs). Intel users will have to toggle HDR and WCG before playing HDR content and turn it off when returning to SDR.

Desktop color depth: Not relevant to video playback, so simply set it to Highest (32-bit).

1920 x 1080p - 60 Hz:  8-bit-10-bit 

Output color depth (8-bit): 8 bpc (Nvidia/AMD); N/A - Auto (Intel)

Output color format: RGB 

Output dynamic range: Full or Limited (as per configuration in section #1)

OR

Output color depth (10-bit):  10 bpc (AMD); 12 bpc (Nvidia); N/A - Auto (Intel)

Output color format: RGB 

Output dynamic range: Full or Limited (as per configuration in section #1)

3840 x 2160p - 60 Hz:  8-bit

Output color depth: 8 bpc (Nvidia/AMD); N/A - Auto (Intel)

Output color format: RGB 

Output dynamic range: Full or Limited (as per configuration in section #1)

3840 x 2160p - 60 Hz:  10-bit 

Configuration here is a little tricky because of the bandwidth limitations of HDMI 2.0.

We will separate configuration into two cases: 4K 10-bit, 60 Hz, and the typical video playback refresh rates: 30 Hz, 29 Hz, 25 Hz, 24 Hz and 23 Hz. Only these lower refresh rates support 4K 10-bit, RGB Full.

Note: Nvidia defaults to the highest bit depth supported by your display. This is usually 12 bpc. You likely won't see an option for 10-bit, so 12 bpc is the correct choice for Nvidia GPUs. 

4K 10-bit - 60 Hz

Output color depth: 8 bpc (Nvidia/AMD); N/A - Auto (Intel)

Output color format: RGB 

Output dynamic range: Full or Limited (as per configuration in section #1)

4K 10-bit - 30 Hz, 29 Hz, 25 Hz, 24 Hz, 23 Hz

Switch to each resolution individually: 30 Hz, 29 Hz, 25 Hz, 24 Hz and 23 Hz, apply the changes below, and click apply. This can also be done during video playback. You can confirm 10-bit/12-bit output by visiting the GPU control panel during playback or by using the madVR OSD (as explained below).

30 Hz, 29 Hz, 25 Hz, 24 Hz, 23 Hz

Output color depth:  10 bpc (AMD); 12 bpc (Nvidia); N/A - Auto (Intel)

Output color format: RGB 

Output dynamic range: Full or Limited (as per configuration in section #1)

Summary - 4K 10-bit: 4K 60 Hz - 8-bit RGB; 4K 30 Hz and lower - 10-bit/12-bit RGB

Note: Custom resolutions can interfere with 10-bit output with Nvidia GPUs. With Nvidia, you must set your desktop to YCbCr 4:2:2 12-bit at 60 Hz to switch to a 12-bit custom resolution. If your desktop is set to 8-bits, the GPU will stay at 8-bits when selecting a custom resolution, even if it was created and saved at 12-bits. 

12-bit custom resolutions are known to be unreliable with most Nvidia driver versions and often won't survive a reboot of the operating system. The best bet for a working 12-bit custom resolution is to input the values calculated by madVR into CRU (Custom Resolution Utility) and create a custom resolution with CRU.

Confirming Output Bit Depth and Color Space (Nvidia Only)

The madVR OSD (Ctrl + J) can be used to confirm the output bit depth, color space and dynamic range. These stats will tell you if the GPU is correctly switching from 8-bit RGB to 10/12-bit RGB at playback start. Currently, reporting is limited to the Nvidia API.



Desktop Color Settings



Set the desktop color settings to be controlled by the media player/media software.

Video Color Settings



Set the video color settings to be controlled by the media player.

Video Image Settings



Disable all image enhancements. This type of post-processing will be handled by the media player.

Power management mode



Power management mode is only relevant to Nvidia. Found under Manage 3D settings -> Global Settings, the lone setting known to cause issues is Prefer maximum performance, which may actually reduce performance. Adaptive is the preffered setting for general video playback.

Nvidia’s Power Management Explained

That's it! Final steps may include configuring 3D output and running through the Configure Speakers wizard from the GPU control panel or the Windows Sounds settings panel.

Absolutely fantastic guide.. Well done for publishing such an informative and extremely helpful document.. You are truly a great asset to these forums.. Thank you sir [emoji106]

[mclingo]

....you didnt have to requote the entire document mate

lol

[Warner306]

 

Thank you.. I actually just seen this now lol
. Sorry about that.. I will give a go tonight after work.. I reverted back to a previous Windows 10 version do you think it's worth upgrading it to the latest version again then try this out.? Thanks.. 

There isn't anything important in the new Windows update. The latest 1809 build could be an improvement, but not enough have used it to know if it is or not. You may want to update, anyways.

Your sharing issue is probably simple. There is a chance it is something odd, but that is also hard to say for certain.

https://files.1f0.de/lavf/LAVFilters-0.73.exe


new LAV is out, different DLL names so these will replace existing LAV filters rather than overwrite so you'll have to delete the old ones from the folder.

XXXXXX:\KODI DS4\system\players\dsplayer\LAVFilters

EDIT: NEV tells me the names were updated in feb so I must have had some old ones still in that folder, names havent changed so should overwrite.

[User 398201]

i installed the exe (standard) to: C:\Program Files (x86)\LAV Filters\
second step - i copied all files from C:\Program Files (x86)\LAV Filters\x64 to------> C:\Program Files\Kodi\system\players\dsplayer\LAVFilters

thene i deleted the old version nubmered files: avformat-lav-57.dll  new ist ----> avformat-lav-58.dll

is this the correct way to do it? last time i wanted to update lav: no video could be played in kodi, only black screen. this time videos in kodi playing well ( i tested 3{1080p, 4k, simple iptv stream})

///EDIT

checked LAV Filter versioin in each panel (property dialogs from kodi) 0.73 = top, thanks Warner306

[Warner306]

Just look at the property dialogs and it should show the LAV Filter version in each panel.

[ashlar]

I still wonder, after all this time, whether DSPlayer could be rebuilt as a binary addon.

[mclingo]

i'd settle for stock KODI adding the ability to use external filters like MPC does

[toki5]

welp, I am confused now. Someone please tell me what the correct settings are for madvr. I am a vizio television. Do I need to set my gpu to ycbcr? and if so should it be 4:2:2 or 4:4:4 with madvr at 0-266 color range. someone please fill me in.
