While DXVA2 is selected as the decoder in LAV Video and a file is playing, if MPC-HC's window is dragged to another screen then the video size resizes to what MPC-HC originally started with. This doesn't happen when software decoding is selected though.

Just noticed that It's pretty difficult to see progress in the FSE seekbar when you're a bit back from the monitor unless the screen is pretty dark. Is it possible to get the progress color darkened or something? Obviously isn't anything major, and I seem to remember you said that you wouldn't rethink the presentation until v 1.0, but just thought I'd mention it.

I have small idea - perhaps not very smart - is there any chance to add display support for YCbCr data without conversion to RGB on RGB output - this can provide capability to change RGB analog output to YPbPr output - very simple adapter (perhaps some buffer only, perhaps only some caps + sync combiner) should be enough to connect any graphic card to YPbPr input of TV (one one typical video modes need to be set anyway) - in normal conditions people need to buy/build ( VGA RGB to YPbPr converter ) special converter from RGB to YPbPr. With such settings - i.e. RGB used as YPbPr output only sync combiner will be required.

I checked, and it did indeed occur with every movie that is 1080/23.976p. Updating to the latest LAV filters did the trick though, so it must have been on their end. Thanks! |

Redone the test with 0.85.2: Now (1), (3) and (4) are the same, (2) is different (in the same way with oversaturated green like in 0.85.1). So using native decoding without dxva scaling is still broken (at least for my setup). With 0.85.2 GPU load with native DXVA decoding is about 0 - 30% HIGHER than copyback decoding (depending on scaling algorithm!) Last edited by hannes69; 6th December 2012 at 13:15. |

this is my cpu and now that i have complained about it, it appears to be acting like when you take a car to the mechanic, it just won't make that same sound or in this case, a slide-show. i will report back later if it starts doing it again. |

AMD CPUs only support SSE 4.1 in Bulldozer and above, so no, your CPU does not qualify.

When Madvr crashed earlier today , I noticed this:

If true, that's why I think an option to select DXVA chroma scaling for such situations would be a good idea since it looks better than bilinear and doesn't require (m)any ressources. |

Madshi, I've just seen a new bug introduced in 0.85.2
If you are downscaling with DXVA2 and switch to anything else, it results in a green image. I have to switch to a non-DXVA2 scaling algorithm a second time to restore the correct colours. Quote:
To get a basic idea of what kind of scaling DXVA2 is using on your system, right click and save this image If you open it in MadVR and switch between DXVA2 and Bilinear scaling on an Nvidia card, there is no difference between the two, and a clear difference when using anything else, for example. As a side note, there are some interesting things that happen when using the anti-ringing filter and/or linear light scaling with this test, and I wonder if something like this could possibly be used to help fine-tune the algorithms further. (it was also interesting to use a multi-coloured one to see how they were blended together) Then again, it's a completely artificial thing that may have no bearing on real-world content at all, so maybe it's pointless. Still, it's an easy way to get an idea of what scaling algorithm DXVA2 is using, through comparisons. |

Hmm it appears my new laptop comes with an nVidia NVS 5200M, as well as the Intel HD 4000 IGP. There's very little information about this GPU out there so I guess I'll have to investigate which one is best for MadVR!

Madshi, how do I submit a freeze report? I'm getting freezes using the NVS 5200M in my laptop with MadVR (no issues using the Intel HD 4000 with MadVR, or either card with EVR).

* I don't really know, but I was expecting at least some kind of darker grey, Linear Light scaling makes it look as if there's hardly and black in the image, at least for the black-and-white checkerboard pattern. I may be wrong, though. Edit: Looks like I'm getting Bilinear upscaling on AMD Radeon HD 6970M when scaling with DXVA. However, I didn't pay too close attention to things like additional sharpening algorithms. Last edited by DarkSpace; 7th December 2012 at 00:24. |
