For the last few months, I've been having a problem with my reds. They look very blotchy and noisy. I'm not aware of having changed anything except for drivers (to the latest build). I'm using the latest MPC. All other colours are absolutely fine.

If updating the drivers was something you've changed then it would make sense to revert that to see if it fixes the issue, besides that you could try restoring default settings via the batch file in MadVR's directory.
Resetting and reverting are the basics when it comes to troubleshooting, always do those first. |

If you're not using MPC-HC 1.7.0, try it (mpc-hc.org). Try pressing (CTRL+J) if you get an OSD in top left corner of the video, post a screenshot, similar to this: Post a list of filters used (in MPC-HC right click on video, select filters). Apart from the files being *.avi, what codecs are used? Preferably post MediaInfo (in MPC-HC: File-> Properties, select MediInfo tab, copy whole text here as [code] block). |

Hi,
I need some help regarding external pixel shaders, no matter what I try I fail to apply a shader. What I have done so far : created the playback graph and all is fine. Then upon user interaction I try to add a shader. Here is my interface definition for C# Interop : Code:
[ComImport, System.Security.SuppressUnmanagedCodeSecurity, Guid("B6A6D5D4-9637-4C7D-AAAE-BC0B36F5E433"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] public interface IMadVRExternalPixelShaders { [PreserveSig] int ClearPixelShaders(bool postScale); [PreserveSig] int AddPixelShader([MarshalAs(UnmanagedType.LPStr), In] string sourceCode, [MarshalAs(UnmanagedType.LPStr), In] string compileProfile, int stage, IntPtr reserved); }; Code:
IMadVRExternalPixelShaders madvrShaders = playbackGraph["VideoRenderer"].GetInterface<IMadVRExternalPixelShaders>(); if (madvrShaders != null) { int result = madvrShaders.AddPixelShader(shaderCode, targetProfile, (int)madVRProperties.ShaderStage.PreScaling, IntPtr.Zero); } Marshal.ReleaseComObject(madvrShaders); Regarding the arguments I'm passing here they are : targetProfile = "ps_2_0" shaderCode = "sampler s0 : register(s0);\nfloat4 p0 : register(c0);\n\n#define width (p0[0])\n....." Am I missing something ? Thanks, -- Stéphane. |

xysubfilter and madvr crash
I just had it crash while I was watching Commie's Monogatari series second season episode two
It crashed specifically while I was full screen around the 3:40 - 4:00 mark. I'm not using full screen exclusive mode. I believe the cause is xysubfilter (not to be confused with xyvsfilter) It will also sometime crash saying it was madvr.dll that caused it I'm using LAV filters 0.58.2, madvr 0.86.11, reclock 1.8.8.0, mpc-hc 1.7.0, and xysubfilter 3.1.0.546 I've attached the crash report in a zip file.

@StephaneM:
Are you using DirectShowLib? Would this be it? Code:
// madVR Filter COM InterOp) [ComImport, Guid("E1A8B82A-32CE-4B0D-BE0D-AA68C772E423")] public class madVideoRenderer {} . . . // (instantiation) m_madVR = (IBaseFilter)new madVideoRenderer(); m_PixelShader = (IMadVRExternalPixelShaders)m_madVR; . . . |

No, I'm using my own interop Library.

The only thing I'm not sure of is if my interface definition is correct or not (for instance the interface documented by madshi for ClearPixelShaders state that this methode expect an int argument whereas it seems to be a bool... Regards, -- Stéphane. |

After toggling a few settings, the problem seems to disappear after switching the decoding matrix to BT.601 instead of BT.709, which is what madVR autodetects. I was getting weird effects in, say Breaking Bad season 3 episode 1, the clouds in the Mexican sky had red blotches. In the later scenes lit by campfire, Jesse's face was blotchy. As if he had a rash! Anyway, at least I know how to fix it now. |
