No, not yet, not sure yet if it's madVR's fault, I have my doubts, but we'll see... Quote:

Can't you just trust in what we said? Namely that native DXVA decoding comes with a small quality loss on some GPUs? That's a fact. *Why* that is the case is highly technical and shouldn't really be very important to you as a user, or am I wrong? It's just the way it is. Use native DXVA decoding if you want lowest power consumption. Use copyback DXVA or software decoding if you want highest quality. My best guess is that CUVID will sooner or later disappear from LAV Video Decoder. Of course only nevcairiel knows for sure... |

Those of you with memory leak problems (sneaker_ger and nijiko?), can you please try the following test builds?
http://madshi.net/madVR89leakTest.rar @nijiko, if you have total PC freezes with v0.89.11, I'd recommend to start with test build 5 and work your way up to build 1, because build 5 is nearest to v0.89.9. So if you have no problems with v0.89.9, test build 5 is the most likely to still work ok, and the risk of getting problems is getting higher, as you get nearer to test build 1. |

I believe you got me wrong, I trust what you guys said, I never said I didn't trust you. I am just curious as to why what you guys have said is true, I want to learn why it is so. Sure, if I was just a regular user, all of that wouldn't be important to me, and I wouldn't care one bit about it. (in fact, if I was an average consumer/user, I probably wouldn't even know about madVR and LAV filters anyway). But I do care. And I highly appreciate the work you guys have done and continue to do. Sorry if I came across any other way.

I think it wouldn't make sense for madshi or nevcairiel to invest quite some time in explanations that only 1 or 2% of the users would understand.
It would probably end up quickly in code examples etc and I think that's not the purpose of this platform. |

I'm struggling to understand the "automatically detect hard coded black bars" option. If I select this option with none of the other options selected my 720x480 (16:9) movie is changed to 720x480 (21:9). If I select "crop black bars" it changes the 720x480 (16:9) movie to 719x360 (21:9). Is that intended?

Thanks a lot. I might have misunderstood the "moving" part. I thought people wanted to see some movies with subs in a certain position and some others with subs in a different position. If that was not the case, then sure, position is important too (although... too big can be handled, too small... you don't read it making subs useless ).

How about the case when DXVA deinterlacing is enabled in madVR (and any form of deinterlacing is disabled in LAV filters)? Would the same issue with chroma loss happen in this case too, irrespective of where the video decoding happened (by the CPU in software, by QS, or by the GPU in copy-back mode)? |

I suppose by the time that happens MediaPortal 2 will be viable and that supposedly includes decent scaling algorithms, unlike the awful bilinear used in MediaPortal 1.

It's really not just "a little bit": The blur is very ugly with cartoons and makes it totally absurd to select a HQ chroma scaling algorithm like Jinc, since it will hardly look better than just bilinear scaling.

2:2 cadence means it's 25 PsF. As long as the field order is set correctly in the container and/or stream, disabling interlacing has the same effect as (correctly) applying weave deinterlacing. So yes, you can add that.

build 2: climbs to 327k, then to 333k but stays there build 3: climbs to 326k, then to 335k but stays there builds 4 + 5: So, basically none of the builds has the extreme problem I have with the release builds. Build 1 is worst but still well below 400k, release builds just grow and grow extremely fast... |

with "crop black bars" disabled: movie 720x480 (21:9) with "crop black bars" enabled: 720x480 -> 719x360 (21:9) I don't think I can make it any clearer than that in the limited space the OSD has available. |

Because in their world you are also using DXVA video processing and converting the video to RGB with that.

My final question is: if DXVA deinterlacing is enabled in madVR, but the OSD reports during playback that deinterlacing is off (because the current file does not need it), is this lossy process still taking place? |
