#1 Use KODI 17.6 because Alpha v.18 is not even close to usable yet.
#2 Windows HDR and color settings switch is NEVER enabled and will significantly hamper madVR if it is.
#5 Don't covert HDR to SDR unless your display is not HDR compatible. Use passthrough.
#6 Driver v.385.28 is the last driver that half way works. Anything newer presents even more problems.

The guide in my signature will offer more details for your general questions than this specific madVR forum.

Really looking forward to "play" with madvr and other settings on upcoming months and hope you could let me know your opinion if the software setup I described above sounds like a good way to go and again sorry if it is too newbish

1. Kodi DSPlayer is a valid alternative for the next couple of years. I used Jarvis 16.1 for two years and the only thing it lacked was support for three add ons out of the 88 installed on my system. I did miss a couple of those addons, however.

Future releases are in doubt but it can work for a couple of years and updates have always been provided by the original developer in the past despite ceasing active development. The benefit of DSPlayer is that content from video addons can be played through the player, which has madVR support. This includes YouTube, various public broadcasters, online sites, magazines, etc. There are also piracy add ons, if that's your thing. There is even such as thing as madVR-enhanced porn (not that I'm an expert on that subject, but it's out there in large quantities). Be careful when installing any third-party add ons, as this can corrupt your Kodi install with badly-written scripts that constantly run in the background.

Regular Kodi with MPC will offer the best add on support and some of those add ons (but not all) can be played with MPC. This varies based on the type of links in the add on. DSPlayer is more reliable than MPC with video add ons.

I don't know if external players work well for live TV. DSPlayer has native support for some backends, but I don't know if it still works with new versions.

2. There is a Netflix add on in Kodi, but it is limited. Something has been planned for v18, but I don't know how complete it will be. If you use the official Windows Netflix app, you will have to toggle the HDR switch and then turn it off again before using Kodi.

3. Use the official YouTube app in Kodi.

4. I don't think you can play a game in Steam and render it with madVR.

5. For projector owners, HDR -> SDR conversion is the same thing as HDR mode in most respects due to the limited lumens of projectors in all modes. HDR -> SDR conversion still uses PQ gamma and similar tone mapping techniques, so it is no different than your projector's HDR mode, just with different algorithms. It could be better; it could be worse. This technology is still being improved for future releases and hasn't finished the testing stages yet.

6. Driver 385.28 seems to have the least issues of all recent drivers, but newer drivers are working for many users. There are still some quirks and bugs with HTPC use, but there is no need to upgrade the driver as no new features have been added to enhance video playback. All features in newer drivers deal with video games alone.

MadVR causing a strange "chirping" sound in videos. (MPC-HC & BE)

Hi, starting last night I started hearing a quiet chirping sound that sounds not unlike a cricket. I've tracked the problem back to MadVR by uninstalling everything installed for playing videos, MPC-HC, MadVR, Re-Clock, and SVP 4 Pro.

I reinstalled everything 1 at a time and tested a video that starts out quiet so it is easier to hear it. It came back near the end of my trial after installing MadVR. I tried resetting MPC-HC and played the video. No chirp. I set MadVR as the preferred rederer and the chirp comes back. It does this in MPC-HC and BE, but not VLC which doesn't have MadVR. I tried applying each component 1 by 1 and still only got the problem once MadVR was activated as a preferred external filter.

Here is a link to an MP3 I recorded of the sound. The sound seems to be constant but is often drowned out by louder sounds. I'm sure it still has an effect on quality though.

http://s000.tinyupload.com/index.php...76119381288677

I'm using the latest ver of all software and have updated my audio and video drivers.

My system is Windows 10 Pro 64
MB: Asus Z97M-Plus (Latest Firmware)
CPU: i5 4690K
Video Card: Asus ROG GTX 1070
Audio Card: Asus Strix SOAR
Audio Listening Hardware Used: Sennheiser HD558 Open Back Headphones

Thanks.

I am almost positive that is coil whine, a manufacturing defect that specific loads can cause to manafest. Try different madVR settings, more or less load can change or eliminate the sound.

I only JUST bought this Asus SOAR a couple weeks ago. If this is in fact a defect I should be returning it. It has a shield over it to prevent this sort of thing. (I thought)

Will Asus see this as a defect, or a "feature?"

Thanks.

That already happened 14 years ago when Kodi was called XBMC, and the result was MediaPortal 1. It supports madVR too, by the way.

I would not assume it is being caused by the sound card, I actually suspect the video card. Coil whine is usually the video card or motherboard but given that it happens when using madVR I suspect the video card. Does it go away if you switch to motherboard audio or swap the video card (if possible)? It can also show up and disappear on its own. I have had both a monitor and video card that eventually stopped whining, but the monitor took months, and it often doesn't ever go away.

Coil whine is very frustrating because it usually only shows up with very specific loads. I have even seen (heard) power supply based coil whine that changed pitch when scrolling the mouse wheel.

People sometimes get some 2-ton epoxy or similar and try to lock down/dampen the chokes enough that they stop whining... with mixed results.

Manufactures rarely accept coil whine as a reason to RMA unless it is really bad, and even then they are sometimes difficult.

OK I tracked it down to the option to reduce compression artifacts. I can change anything else, turn stuff on, but once that 1 setting is off, the noise stops. So is this a real defect in my sound card or just that this 1 option pushes the card past its intended limits?

Also, I might as well ask. I've been using JINC with reduced ringing artifacts. There's other options like the multiple NGU options, DXVA2, Super-xbr, and I believe in the player I can pick CUDA since I have a GTX 1070.

Which options should I use, and if I should use one that has other options like doubling, quadrupling, etc, what settings would be best for my system?

Thanks

Well when I changed the "reduce compression artifacts" from High to Medium the pitch of the whine changed.

It's annoying and I have it too with my 1060. Try using DX11 decoder in lavfilters and dropping NGU quality to high. Should make a big difference. I also stopped using RCA since it helps a bit. I very much doubt you can return the card, but you're welcome to try.

I did try to troubleshoot the problem further at one point and I'm pretty sure it has something to do with Vrel limit, but I kinda gave up at that point and admitted my loss. I wonder if undervolting would help...

Hey all, I'm having a torrid time trying to get custom resolutions working on my system

I feel like I've tried everything but I always seem to get a frame drop every 4 and a bit minutes.

Is this currently just not possible with the latest Nvidia drivers?

I'm almost ready to give up getting this to work as it's becoming so frustrating

It isn't quite not possible, at least for one refresh rate, but it is not easy.

I have had a lot of trouble getting Nvidia to actually USE the custom refresh rate with the new drivers... I found that deleting everything out of Nvidia's custom resolutions, effectively disabling that feature in the drivers, and then letting madVR do everything including adding and changing to the custom resolution worked better for me.

Giving up and using smooth motion... is not totally crazy.

Coil whine usually occurs with a specific combination of graphic card & PSU as in another PSU might not trigger the whine at all FWIR.

The funny thing with mVR is that upscales made by HDTV channels look totally facepalmic in comparison but then again I know a guy who does encodes for netflix and he's using the same crappy profile for everything in single pass so I guess HDTV technicians don't care any more than he does.

So you are saying you prefer mVR? That's very surprising coming from you! x)

With some older driver branch - don't remember which one - I had kind of the same issue you have, with clipping. I had to set the GPU (and TV of course) to Limited to get it fixed permanently but of course you then lose in picture quality.
Is YCbCr the only mode that fixes it on your TV, or does RGB Limited works too?
Do you by any chance have another device to test with?
If you have an NVIDIA, try changing the "Content type reported to the display" setting and see if it changes something. When I had that issue with NVIDIA drivers, changing that option to literally anything else than the one currently selected fixed the problem until the next display resync, at which point I had to change it again.
The problem was then fixed in the following driver branch.

Finally got to bottom of it on my setup - just sharing as it may help others with an Nvidia card and a Samsung SUHD set (using HDR+ and colour space to Native to scale up and out into BT.2020 for SDR content, and HDR+ and colour space Auto for HDR content)

If I set Madvr to full, I have to set Nvidia to 4.4.4 limited and the Samsung to limited to get anywhere close to correct colours, clipping levels and image noise (for both SDR and HDR).

However, the best set up here now (after many hours of testing back and forwards) is

Madvr = Limited TV Levels
GPU = Full RGB, 36bit for 23hz etc, and content type set to full screen videos
Samsung TV = Limited/Low

This may, or may not help others with a similar set up to mine.
