madVR - high quality video renderer (GPU assisted)

[DragonQ]

Well then you're using software decoding with MadVR. If you really want to use DXVA2 with MadVR, use DXVA2 Copy-Back mode.

Well I found a temporary solution to getting fullscreen exclusive working in Windows 8 - just kill Windows Explorer first before you play a file, then fullscreen excl. works =)

EDIT: Actually a slightly more convenient way is to just 'Restart' explorer (not kill it) - this also seems to work. I don't know exactly why just doing this fixes everything, but it does.

Just a quick question...

Is there a difference in using madvr built in h.264 decoder or using lav decoder or ffdshow performance wise and IQ?

Cheers!

A noob question.

I am using mpchc x86 + hali media splitter + lav video x86 + madvr. Should I set LAV video configuration to use hardware decoder NVIDIA CUVID? It's set to NONE at the moment. Everything works fine.

I selected LAV video x86 and lav audio x86 during lav installation (I didn not select the LAV splitter).

Using GTX 680 under Windows 7 x64 SP1.

Why fix what isn't broken?

It has one? O_o
Cuz I use ffdshow (along with madVR) so it could play 10bit video

[Kado]

Well... Maybe some multi threading optimizations or new libavcodec versions as lav filter and ffdshow are updated more regularly... They all play 10bit though...

It's just that i recently swapped from ati to nvidia. Maybe I should take use of hardware acceleration?

Anyway tried it and seems to work fine with both none and nvidia cuvid.

Had to do the inf fix for 0-255 rgb before install.

How can I tell if I need this fix? (I'm using a laptop with nvidia 9600m GT + hdmi)
Thanks

DXVA2 Native is the best if it works because it uses the least resources and power. DXVA2 Copy-Back and CUVID are the next best options for hardware acceleration, especially if you want to use MadVR (which doesn't work with LAV DXVA2 Native).

Black will look grey. washed out...

If madVR can't be used with LAV DXVA2 native, then what is the next best renderer to use?

[DragonQ]

EVR I presume.

I use MadVR on my desktop with DXVA2 Copy-Back but my laptop isn't powerful enough to play some 1080i/25 streams without using DXVA2 Native, so I use EVR instead. I also use EVR on my HTPC but that's purely because MediaPortal doesn't support MadVR, unfortunately.

Well, the problem is that it's all relative. How can I be sure of that?

If you can get a pure black image, and make it fullscreen, you can either just try to remember how dark it was compared to the side of you're TV / rim before and after, or perhaps take a photograph before or after trying to keep the camera in the exact same position. For me its quite obvious as when it works, the black is as jet black as the rim of the TV, when its not OK, its worlds away from being anywhere near the same as the TVs rim.

A solution I found, instead of having to edit the inf file (which means for example the driver won't install then in Windows 8 as it has been modified), I install the NVidia drivers normally and open regedit and simply search (Ctrl-F) for an nvidia related drivers area entry like perhaps

UserModeDriverGUID

Everywhere you find it (F3 to find next occurance), add the DWORD entry below next to it.

SetDefaultFullRGBRangeOnHDMI

setting its value to 1.

Then just reboot, or perhaps change resolution once or twice, and the color difference will noticibly kick in. I'm sure someone could make a nice little .bat script to do this also Might be a nicer solution than editing inf files all of the time.

Pardon me if this has been asked before, but is there any difference, all other things being equal, between madvr and evr custom pres when playing 1080p on a 1080p display? I take it madvr has better scaling etc but is any scaling actually done in this case? What about a resolution such as 1920x800? Does that need to be scaled?

Thanks!

The short answer is yes, scaling is done even if the width and/or height match the screen size and madVR does a better job of that than any other renderer does on the basis of objective and subjective tests and data. The long answer exists on the first page and within previous pages of this thread.

It's hard to notice given a 1080p on 1080p display, but if you playback any free to air stuff at lower res which is then scaled up, EVR-CP is absolutely horrendous. MadVR is the only renderer capable of giving me exactly how my sammy TV would scale the video. My wife used to complain recorded TV shows look inferior (and thought it was all normal coming from VHS days) until I changed it to MadVR.

Although one thing I'd like to point out is that the scaling algo of my sammy TV tends to lean towards the softer ones with little ringing. Those algos provide the best match.

I often watch videos when my monitor is in a vertical orientation (1200x1600) out of laziness, but I noticed that under these circumstances together with the LAV filters, madVR dies horribly. It does not display any video, and then the audio stream dies within two minutes. Then, depending on the video, mpc-hc crashes. This is completely fixed by changing the orientation back. I am not sure if this happens with ffdshow, but it definitely happens with the LAV filters.

Actually, I believe the most important feature of madVR is not scaling, but the fact that it avoids (almost) all the messing up your video card driver can made. Another one is madVR use the best possible conversion/dithering if you need one. Personally, the reason I first use madVR, despite the fact that my GPU at the time cannot quite handle it, is the better dithering. It clearly show less color-banding for me.
