madVR - high quality video renderer (GPU assisted)

On the bugtracker, huhn said a time ago:

You said that he's right. Now you're saying that it should work with any source that can be turned back to progressive. I suppose that interlaced NTSC is that kind of source (at least YADIF can turn it back to progressive!). I'm confused.

this is just a miss understanding.
a telecine source is still technically an interlaced source.

interlacing is very confusing.

madVR film mode is a detelecine filter/reserve telecine filter alias IVTC. it only works on telecine sources.

madVR video mode is an deinterlance filter it should work on all sources but quality may vary a lot.

telecine is just a way to create a interlaced source by using telecine. the telecine can be reversed. this type of interlacing is used to create 50/60i from 24/25p. IVTC can reverse this type of source back to 24/25p

a source that is interlaced but doesn't use telecine can't be handle by Film mode and can't be reversed. there are no information to recreate the original progressive frames so new progressive frames are created. this type of interlacing is used to create 50/60i from 50/60p.

all deinterlacer or IVTC algorithm create progressive frames.

an modern deinterlacer may try to use IVTC for better results too but they can't match a normal IVTC algorithm for multiply complicated reasons.

this may help or just confuse you even more:
https://en.wikipedia.org/wiki/Interlaced_video
https://en.wikipedia.org/wiki/Telecine
https://trac.handbrake.fr/wiki/Telecine

there are still special types of interlacing making it even more complicated.

There are custom APIs available from each GPU manufacturer for stereoscopic output in Windows 7 [...] while in Windows 8 it's built into the OS.

Just to clarify, does that mean that on win8+ you don't need 3DTV Play for nvidia GPUs anymore?

I've found an issue with madvr 90.1 . With potplayer if you minimize the window and open it, the video freeze but the sound continues . to start the video again you need to enter FSE.

89.xx works fine . tested in both windows 8.1 and windows 10 . different drivers , 970GTX and 970M laptop , Madvr +FSE D3D11 + 10bit

I managed to crash madvr v 0.90.1. Pastebin of the error dump is here:

http://pastebin.com/fqKG6L3a

I was just doing some regression tests with nvidias stereoscopic 3d mode enabled in trying to get the situation down pat for my nvidia bug report. Most of the time I dont get madvr crash reports where MPC-BE crashes instead, but this time it did happen.

[Schwartz]

The strange freeze bug happened again. Some more info. MPC-HC froze up almost completely, with a slice of audio being played every 4 or 5 seconds. Ctrl-J did not do anything. Pause-Resume fixed the audio only. Audio started playing again but video continues to be frozen.

The log is here: http://pastebin.com/LAUrQ3Eg

nevcairiel, madshi - I found the reason that 3D is not working, LAV Video can't load libmfxsw32.dll/libmfxsw64.dll from installed path (C:\Program Files (x86)\LAV Filters). CDecMSDKMVC::Init() output CDevMSDKMVC::Init(): MSDK not available and out with error.

When i copy this .dll to C:\Windows - all working, thanks

[huhn]

are you using windows 10?

in my experience the "C:\Program Files (x86)" folder has special needs on win10 different from windows 7/8 but i don't have a system to test this.

if yes.
is possible for you to install lav to something like "d:\lavfilter" and test it without the DLL in the windows folder?

Don't working for me on 2 different PC with Win10 Ent x64. Working only if move .dll to the directory thats in PATH enviroment.

Well, I'm not having a lot of success so far. I originally tried to get this to work in MC21 and when I enable 3D in the nVidia control panel or in Windows Display settings and try to play a 3D MKV, it crashes the player. So I figured I'd simplify my life while testing and get MPC-HC set up and I'm having the exact same problem. Crashing culprit is c:\windows\system32\nvwgf2um.dll which presumes it's dying in nVidia land somewhere. I also copied the intel DLL to my Windows dir (thanks for that tip) so it's finding the DLL ok, but, something is not very happy on my machine. Windows 10, nVidia 680, nVidia 361.43 driver installed. Any magic tricks I can try to get this to work? I'm VERY excited by this 3D development. I know a lot of people couldn't care less about 3D, but, I have a good setup for it and quite the collection of 3D blu-rays I'd love to convert to MKV. Thanks for the help!

[jmone]

I've not got 3D working in JRiver MC either yet.

On the crash, when I "reset" the MadVR settings it sovled the crash, I then started re-enabling stuff and for me it is the D3D11 mode that seems to cause the crash.

I'm also nVidia (660Ti) Windows 10 64-Bit

New chroma algorithms appear too sharp to feed SR to my eyes but I'll need to run more tests, still PQ is pretty dang sweet atm to say the least.

The new OSD looks great too as it was pretty painful to read before, I would personally enjoy a hotkey to get to the control panel directly but maybe it's already there and I missed it somehow.

what strength do you use for it? from the default 3 down to 1 makes a difference of about 2% gpu usage on my gtx650. i'm trying to decide if its worth the extra 2% or not.
thanks

BRILLIANT discovery! Copied the DLL and all works great now on my Nvidia machine. Thank you!

[jmone]

Copying the DLL into the Windows folder "almost" works for me.

Now I can see my TV do the Black Screen with change of Refresh rate thing but oddly it seem to happen a couple of time (and the TV complains about losing the HDMI connection in the middle). When the image comes up madVR is using D3D9 not D3D11 and I get a Side By Side image.

[huhn]

are you sure you used a MakeMKV MKV remux for this test?

these files are not played as side by side.

[jmone]

Yup - even did a new mux to be sure. When I say Side by Side it even includes the Ctrl-J OSD

[Nullack]

Huhn I can see that test result too. I believe mate it happens when you have correctly installed the Intel media sdk DLL, but a user has not correctly enabled stereoscopic mode in their nvidia control panel. I see the exact thing, side by side, by doing so and Ive done my own remux from one of my 3D blurays using MakeMKV

[Balthazar2k4]

Does anyone have smooth 3D playback on a Haswell or later NUC? My 2D content works great on it, but 3D is very jerky. The processor is showing minimum utilization so I am wondering if the GPU is maxed out with 3D content.

Same here in MPC-HC x64. Happenes with 0.90 too.

btw, I can confirm that the interlaced ProRes is fixed, thanks.
Film mode doesn't support such files yet, right?

[4h4h270]

problem sovled!, I just set madvr disable 3d when playback 3d,then the picture become SBS, I just need to choose SBS 3D in my monitor, works perfect!

----edit----

After copy libmfxsw32.dll/libmfxsw64.dll to c:\windows,3d playback works,still get some crashes,and only left eye image

----edit----

3d playback doesnt work on my pc same as before.

If I enabled 3dvision in nv contorl panel,when madvr goes fullscreen crashes every time,windowed no stereo effect.

madvr cant enable/disable 3d, everytime I have to change settings in nv control panel.

Here's my debug log

film mode only supports 8 bit. disabling all 10 bit and high options in lavfilter should work. still better than judder i guess.
