As said before I'm a perfect noob, Can you help me with zoom? In MPC-HC I can find only 50%, 100%, 200%, Automatic. BTW yes I have an iPhone5 to make a video when is ready I'll PM you.
Thx for your support!!

Edit: I tried with 200% zoom and windowed mode (after unchecking exclusive mode in madvr settings)... nothing changes. I'm going to record the issue. Check your PM soon.

madshi, is there any potential fix for the secondary screen becoming unusable once a video is in exclusive mode on the primary screen? No window can be focused unless the video is in windowed mode on the primary. Should I fill out a bug report for this or is this behavior expected?

Also, this may or may not be related but I was playing around with DisplayFusion which creates the taskbar on all secondary monitors and the unresponsive monitor problem shows up on all screens, regardless of which screen the video is playing on in exclusive mode.

while my internet was down for an hour i decided to experiment with the madvr deinterlacer. I noticed when i went into the nvidia control panel and disabled inverse telecine, madvr stopped dropping frames and the gpu usage went down by 30%. so my question is what is it about inverse telecine that causes it to use so much power?

@madshi, thanks.

@cyberbeing, i did installed lav filters since the beginning. now i need to ticked the matroska at source filters to get rid of low merit. thanks.

That's weird. Jinc3 should push GPU up *much* more than just 5%.

Not sure what to say. Maybe your PC is simply not fast enough for this. Or maybe the MPC-HC internal sub renderer does something weird. I don't really know. I do recommend using fullscreen exclusive mode...

Just press the "9" key in the num block. That will very slightly zoom into the image.

So this issue only occurs with 720p videos but not with 1080p videos? Sounds weird. Does it occur with *every* 720p video? And does it *not* occur with every 1080p video? And you double checked that VMR9/EVR don't show this problem with the same 720p video, correct?

What happens if you start a game in fullscreen exclusive mode on the primary monitor? Can you then focus windows on the secondary screen?

Does that have anything to do with your bug #85? It's hard for me to handle bug reports if you write something to the bug tracker and something to the forum...

no madshi this is unrelated, just a general question

Well, NVidia and AMD (not sure about Intel) support per pixel film mode detection and inverse telecine. It's not too easy to do this well, so it does cost quite a bit of GPU performance. madVR's IVTC (which is inverse telecine + decimation) runs on the CPU instead (for now). It performs better and has better quality, IMHO, compared to what NVidia and AMD are doing. However, it's more limited in functionality: It's not per-pixel and it doesn't (yet) auto-detect whether the content is video or film.

New unreleased Intel driver for Ivy/Haswell for those who want to try, don't have Intel graphics myself...

As odd as it may be, I don't actually have any games installed to test this with :/

But, I do have VMware installed and according to this: http://pubs.vmware.com/workstation-9...F51A0F03E.html I can go into exclusive mode with virtual machines.

So, when I try this with virtual windows and linux machines on primary or secondary monitor, the mouse becomes locked to that screen which prevents me from changing focus unless I use the keyboard which then causes VMware to take the virtual machine out of exclusive mode and into windowed fullscreen mode instead.

According to other gaming forums, a similar behavior is exhibited while playing games in exclusive mode, but I can't say for sure.

So this does not seem to be a madVR problem, but a general limitation of FSE mode, correct?

I suppose so. madVR is better in that respect I guess. It frees up the primary monitor while in FSE mode on the secondary.

Is it possible for madvr to tell when the current refresh rate is 59.99hz and not 59.94hz? I set madvr to switch to 1080p59 but when the display is at 60hz already, madvr does not switch to 59hz. ie it doesn't distinguish between the two. If the display is currently at 23hz, otoh, it does switch to 59hz.

Just found a better setting which runs much stable with madVR unless the GPU is overloaded.

CPU queue size: 16
GPU queue size: 16
back buffers: 8 (both window and FSE)
present several frames in advance: [checked]
after last render step: [flush & wait(sleep)] or [flush]
others: [don't flush]

It prevents frame dropping at dynamic GPU frequency change during the playback which even happens to the powerful HD7970.

On my ION system, the tearing does not happen to window mode now. It is verified with the observation on the quick horizontal panning scene for 24fps contents at 60Hz output. (If smooth-motion is ON, it still happens...)

Some people notice the present queue number keeps dropping or low even GPU loading value is not at 100%. But I can say the root cause is often likely overloaded GPU. It happens to my ION system with 1920x1080i60 contents at any window size. If GPU deinterlacing job is required on such so-so GPU, it causes frame dropping when the GPU loading goes up about 70~%. (I think...)


ps: The above setting is verified ok on my 2 systems: (OS is win7x64 sp1)

Mini-server: Core2Duo P9700(1.6 ~ 2.8GHz) + 8GB DDR3-1333 + ION-LE GF9300 256MB share-mem (Geforce 314.22) + Bi-linear + Window mode ==> Dell U2412M 1920x1200p60

HTPC: Core i5-3570K(1.6 ~ turbo 3.8GHz) + 8GB DDR3-2400 + HD7970 3GB DDR5-5500 (Catalyst 13.6 beta) + Jinc3_AR + FSE + auto-refresh-rate changer ==> Sony 65HX920 1920x1080p24/p50/p60

Hi,
I did some tests yesterday with GPU-z to check GPU load and there is something strange. Here are the result :
1080p videos : 0% GPU load ; ~7ms rendering time
720p videos : 30% GPU load ; ~11ms rendering time

Here are my specs :
Hardware :
Intel Core i3-2100 @ 3.10GHz
AMD Radeon HD 6850
CCC :
screen : 1080p60 ; color 32bits
color & quality settings : all unchecked
pixels : RGB 4:4:4 (full range)
everything else is default
LAV :
default settings
xy-VSFilter :
default settings
madVR :
display already calibrated ; BT 709 ; ppc 2.20
Jinc 3 AR / Jinc 3 AR / Catmull-Rom AR,LL
CPU 12
GPU 8
backbuffer : 4 (both window and FSE)
use a seperate device for presentation
smooth motion ON if judder
everything else is default

Even if the video match the screen, GPU load should not be 0%, right ?

Sorry, it was my fault. MadVR had used intel GPU and not nVidia.
I have renamed mpc-hc.exe to game.exe (thanks for the hint) and now it's working flawlessly!

I'm curious which are your madvr settings (scaling chroma,image, resolution,etc) that you use with your nvidia ion i have one too for my htpc with an atom 330 and i haven't been able to experience a totally smooth reproduction in madvr yet.

Scaling : Bi-linear
Subtitle: ASS or SSA
Player: MPC-BE x86

1280x720p24 H.264 Hi10p -> 1920x1080 [ok]
1920x1080p24 H.264 Hi10p -> 1920x1080
[ok] for < 6 ~ 8 Mbps source (I think)
[frame drop] for >= 10 Mbps source

1440x1080i60 / 1920x1080i60 MPEG2-HD -> 1920x1080p60
[frame drop] if GPU deinterlace is in use
[ok] if GPU deinterlace is turned off

For the contents with ION chipset's DXVA decoding via LavFilter's video, it should just work fine with Atom330 CPU.

With Atom330, FFMPEG in LavFilter can only decode some low-bit rate SD H.264 Hi10 contents. Atom330 is too weak to decode any high bit-rate HD one.

The C2D P9700@2.8GHz (6MB L2 cache) is about 4 times as powerful as Atom330 on 1~2 threaded program. It is just fast enough to decode regular Hi10 FHD 24fps contents. In addition my ION MB's memory sub-system runs at dual-ch 128-bit DDR3-1333 mode, not the single-ch 64-bit DDR2-667, DDR3-800/1066 one on most Atom330+ION MB or Mac-mini. (ps: MB is AOpen GP7A)

With the H.264 4K contents at 60~100Mbps or HEVC 4K, it needs Core i5-3570K@3.4GHz (4core 6MB L3) computing power to do that. My previous HTPC was C2D E8400@3.6GHz (2core 6MB L2). It can only handle those < 15 Mbps ... if I don't remember it wrong.

madshi, can’t you convert the subtitles from PC to TV and then blend them onto the video instead of converting the video to PC, blending and then converting back to TV?

Sony PS4 list price --- US$399

It will be interesting if MPC-BE + LavFilter + madVR can be run on it. Just like most x86 PC, this box with x86 CPU+AMD GCN GPU obviously runs with the regular Win8 OS (Sorry, not quite sure if it is the same with XBox One ... most likely a custom-built OS derived from PS3 OS. The only chance is another Win7/Win8 OS installation.). PS4's GPU should be capable of running Jinc3_AR scaling algorithm at 60 fps for SD(480i) ~ FHD(1080i/p) contents.

I don't think any custom-built HTPC with the same price is capable of such GPU performance. US$600~800 might be the minimum cost.

Nice point and that would be an awesome-best bang for your buck as a media player, but i doubt our favorites movie players-decoders-renders will be easilily ported without waiting a LOT, i don't think sony will give us a piece of cake crackable console, (got to learn from the past) but anything is possible, time will tell.
