LAV Filters isn't used for decoding in that graph at all (instead Microsoft's default decoders are used). Just delete the MS filters and insert desired LAV Filters manually (via Graph -> insert filter). Afterwards you have to make the right connections.

hiya there, i need some help please.
previously i use mpc-hc+lav+madvr, they work great. (pc is i7 7700k stock, 16gb ram, gtx 1080ti, 1080p monitor) i set lav video to dxd11cb plus software deinterlacing recently i switch to a 1440p hdr monitor and trying some 4k hdr stuff. but they plays very laggy, so i use dxd11native to play hdr content the problem is now with dx11native's, with interlaced videos i cant use software deinterlacing of lav, and videos that previously play smooothly, interlaced to 59 fps, now plays at 29fps with many vertical line during movement. so basically what i want to ask is. 1. is it possible to play 4khdr content with dx11 copyback? (at least on my current setup?) 2. is it possible to get deinterlacing to work with dx11native? |

Is it normal to experience clipping even when the mixer is set to default levels (.71 for center mix and surround mix levels)? This post suggests that those values should be set to .29 to eliminate any potential instance of clipping, but is that correct?
My understanding is that "Normalize Matrix" reduces the natural dynamics of a track, so I do not want to use that. Last edited by Megalith; 11th February 2018 at 02:13. |

It does nothing of that sort. It only reduces the mixing coefficients to avoid any potential of clipping - ie. it reduces the overall volume, the dynamic range remains untouched.

I have resorted to manually switching to D3D11 Native in LAV settings when I want to watch 4K (which is not that often).

uhd playback work in copyback mode with dxva CP or d3d11 CP. matter.
there could be a lot of possible issues why it is not working but hard to address like this and i don't see a single reason why lavfilter has anything todo with that. |

You're correct it does it using the Microsoft DTV-DVD Video Decoder as well. Wonder if this affects all AMD video cards or just a bug with mine. Like I said I have tried different drivers. Thanks! |

I understand. It was the tool-tip description that was confusing me: it says that the feature ensures a consistent volume level and that the volume level in one file will not change, so I assumed that the dynamics were affected in some way.

Sorry for being a total noob about this and sorry again if I'm posting my question at the wrong place.
But all of a sudden and without any changes on my part mp4-files have issues with the sound. When opening the file in MPC-HC all I get is this warning that says I don't have the right codec installed. The files have worked before but could it be some stupid update to Win10 that has changed things? I have Win10 build 16299 and when the problem was noticed I ran MPC-HC x64 1.7.13 with LAV 0.70.2.88 and tried with a clean install without change and then tried MPC-HC 1.7.14 with no change. The text in the warning window is this if it's to any help. Code:

Is there any interest in adding plugin support for external video manipulation such as Vapoursynth? All development of ffdshow has basically discontinued in favor of LAV, but this is one feature that I haven't been able to find a new solution for.

I'm using latest DXVA Checker v4.0.0 with Windows 7 x64 SP1 with all updates installed.
My CPU/GPU is a SandyBridge Core i3-2100 - latest driver v4229- and using the MF64 Microsoft's H264 MFT decoder, the app allows me to benchmark the "Decoding Performance" using D3D11. Playback mode for MS MFT D3D11 is disabled and all the other decoders like MS DS/LAV/Intel MFT can't be used with D3D11 even in "Decode Performance" mode. So, only Ms MFT decoder can leverage D3D11 and only in "Decode" mode but: How is that possible using Windows 7 ?

It probably uses DXGI_FORMAT_420_OPAQUE, which is the only supported D3D11 decoder output format on Windows 7, but you can't really do much with it. You can decode it, and display it somehow (although I dont think EVR itself even supports that), but you cannot access the data "untouched", as such it really doesn't work well for what LAV wants to do with it.
The problem on Windows 7 is not that the decoder doesn't work, because it technically does - the problem is that NV12/P010 are not supported in D3D11. You need Windows 8 for that. But without NV12/P010, the decoder is mostly useless for most use-cases.
