DXVA-->how to control brightness-contrast-and so on
It seems that MPC HC can't control brightness and contrast via ffdshow while playing h264 DXVA.
Same happens while watching DVB HD in DXVA on WinTV. Any solution? t.i.a

Forgive me, could you be more clear?

Nope, overlay won't work as EVR is in use.
Thanks anyway, let's see if someone has a solution

The problem is that I don't even know what a pixel shader script is and how to code it -.-
edit: I think that you hit the point, the problem is how to find a script that does the work, I only saw sharpen scripts and similar ones.

If I were you, I'd get a colorimeter(even a cheap one, like a Spyder II) and calibrate my display properly(D65/2.3 gamma).
If you just wanna do it by the eye, you can play around w/ this sort of script: Code:
sampler s0 : register(s0); #define const_1 (16.0/255.0) #define const_2 (219.0/255.0) float4 main(float2 tex : TEXCOORD0) : COLOR { // original pixel float4 c0 = tex2D(s0,tex); return (c0 * const_2) + const_1; } Last edited by leeperry; 10th December 2009 at 18:04. |

The lcd works quite well, but you know, a lot of movies (most part) is so dark... ffdshow is always set on GAMMA 1.35
Thanks for the script, let's try... edit: none of the stock shader scripts work (i.e sphere, sharpen and so on). Hd3850 and latest catalyst on 7 x64. I suppose that your script even wouldn't work... What's wrong?

if the picture is dark, that's most likely because the native gamma of your screen is very low...your best option is really to grab a colorimeter(a second hand Spyder II should cost no more than 30/40 EUR, and you'll even get accurate colors).
ah well, do scripts work w/ non-DXVA material? you need some old DX9 DLL to get them working on Vista/7 I think |

The gamma is ok with photos and text, if I'd raise it my eyes will get tired in a few minutes.
The problem is ONLY with movies. No, the scripts don't work on NON DXVA material even

How would you know that ffdshow set 1.35 gamma? The movies are dark only with ffdshow or with other decoders too??
Go to RGB conversion in ffdshow and make sure input levels are standard and output levels as your monitor settings. |

Ffdshow IS set, but not automatically.
I decided that it was a nice gamma value for most movies. The movies are dark with all decoders on earth, maybe is an eyesight problem because movies look always dark on every monitor or tv, but I don't think so, because seems like my eyesight is almost perfect. @lee Yes, I can see all the boxes on the 00 to 100 white to black test, but anyway I don't want to change the monitor values because everything but the movies look good to me, and increasing either gamma, contrast or brightness will result in eyesight stress while surfing the web, doing photo editing or whatever. That wouldn't be a good news as I only watch some movies rarely, so the best workaround is to set gamma while playing via DXVA. By the way I already have dx9, I've just used them in Dirt 2 until 5 minutes ago

doing photo editing on a monitor that's not perfectly calibrated is a major hit or miss IMHO.
well on x64 OS, you got DLL's in many different system folders...you need to copy some 32bit d3dx9_**.dll in your MPC-HC folder, might just be d3dx9_41.dll: http://www.cccp-project.net/forums/i...p?topic=3761.0 |

Nothing seems to change (of course I copied the system32 one and not the WoW94 one).
Curious...

There is gamma control in ffdshow in "Picture properties" menu. But if all your videos are too dark, then you could have messed with your drivers. Whats your graphic card? Do you have video levels setting in drivers control panel? |
