Thanks It's a pity you haven't reply on my questions So you'll make LAV Filters with your fork of FFMpeg also with 1. LAV Splitter can recognize AC-4 (and desirable MPEG-7) streams so show them in LAV Splitter's properties in players while playing video with AC-4 track I've uploaded here; 2. LAV Splitter supports support true streaming directshow interfaces (as I understand like i.e. Elecard MPEG Push Demultiplexer) http://www.smartdvb.net/bb/viewtopic...3&t=1768#p6902 3. LAV Video Decoder can deinterlace quasi-interlaced h265 streams (discussed here before); 4. LAV Video Decoder has built-in correct HLG to HDR10 (or even better directly to BT.709 colorspace as mpv does) conversion (not just passing to renderer but if you can write HLG to BT.709 shader tell me too) features together let's talk about price (may be in PM) Last edited by VictorLS; 1st February 2020 at 00:44. |

I am not a license expert, but imho this is violating GNU GPL (https://github.com/Nevcairiel/LAVFil...master/COPYING). So no need for this nonsense here ...

b) Are you sure you can to implement all four wishes from my previous post? c) As I understand you're don't write shaders. Am I right? Last edited by VictorLS; 1st February 2020 at 13:40. |

Most of us here are trying to help without asking money, even developers and professional developers like nevcairiel - I'm not - who is the developer of LAV filters. I respect your time and effort to write code, but i really don't think you are asking money in the right place. So, eventually, my wish is that nobody will "bite" from your teasing efforts to make money from doom9 forum and leave this place quitely, as you will find nothing here to gain profit.

I don't know may new versions of DVBViewer work with shaders but in donateware app SmartDVB (about year with many other useful things SmartDVB had being implemented EVR Custom Presenter [EVR-CP] code let be used in app SmartDVB by Russian author of freeware player MPC-BE and shader support in EVR-CP - I knew DVBViewer let choose Custom Presenter by check) to watch HLG on SDR monitor with ~ right colors like mpv does - I gave link where HLG is being discussed at doom9's forum several times in this thread - last one at the end of this post I hoped HLG to SDR shader will be written ~ in an year by someone but was wrong (or I can't find it in Internet). Or just wait I guess long enough time (if your computer is powerful enough) when i.e. madVR will process HLG (as it does HDR now) well. You're right - it's one of row from my long enough wishlist Quote:
there isn't sense in new thread and discussing with richardpl here too but may be anyone know Denmark's CeeJay.dk http://ceejay.dk/ (he write great SweetFX shaders)? If so reply to HLG processing for good picture on SDR monitor thread, please. Last edited by VictorLS; 6th February 2020 at 07:15. |

here you go:
https://github.com/Aleksoid1978/Vide...rrect_hlg.hlsl the line/word about sRGB(it's bt 709 with gamma 2.2) is wrong because sRGB doesn't have a gamma of 2.2 but whatever. yes madVR should processing HLG pretty much everything it needs is already there but it is as it is right now. but most importantly lavfilter delivers HLG meta data so it has nothing to improve in this part anymore. |

Repeat: much large Convert HDR to SDR shader works well enough even in WinXP, and Aleksoid1978 said correct_hlg.hlsl wouldn't work anywhere (as minimum yet) so it implemented in MPC-BE's EVR-CP and don't give correctly colors while playing HLG files. So more research needed - I know it's hard task but I hope to solve it - new season of Formula1 is coming...
Btw I saw absolutely smooth and fluent with modified by Aleksoid1978 LAV Video Decoder 0.68.1.35 has just become Free-to-Air Turkish 4K 3840x2160р50 4:2:0 10bit channel in WinXP with VMR7 (with EVR some worse - sometimes small tearing present) which can be zoomed to Native pixel-to-pixel 3840x2160 on my 1920x1200 monitor (so just 1/4 of video is visible) in lastest version of app SmartDVB and I've written goal 20200206-011432_DIGITURK 4K.ts (376 MB) https://transfiles.ru/97bvd Last edited by VictorLS; 6th February 2020 at 15:40. |

@nevcairiel
Hello. I want to remind you of the old problem with cropping support in MKV files. Here are additional test files - crop_mkv.7z.

As an example, let's take a look at "crop_all_sides50.mkv" that you have uploaded. It's pixel dimensions are 1280x960; it has cropping of 50 pixels on all four sides and it's display dimensions are 1280x960, too. This means that the frame 1180x860 that exists after cropping should be scaled to 1280x960 (i.e. 4/3), so that adding the cropping parameters has made the video anamorphic. I doubt that this was intended. MPC-BE (with its internal filters) honours the spec in this regard. Btw: In most instances, there is a way to create files that are played with the correct pixel aspect ratio on players that support the cropping flags as well as on players that ignore them. The key for this is the fact that the default value of DisplayWidth is PixelWidth - PixelCropLeft - PixelCropRight (similar for DisplayHeight). So if you have non-anamorphic content where you simply want to cut black bars/pillars away, you simply add the desired cropping parameters and remove the DisplayWidth/DisplayHeight elements afterwards. Players that honour the cropping flags will crop and infer the Display dimensions to be what the default value I just mentioned is; players that ignore them will simply infer DisplayWidth = PixelWidth and the same for height and both will play it with the right pixel aspect ratio. (The default value only applies if DisplayUnit is set to pixels (the default value). Unfortunately, using pixel aspect ratio as DisplayUnit is not possible, as this is not a permitted value.) If the source file is anamorphic, it is not always possible to create files that are played with the correct aspect ratio by both types of players. But one can crop in one dimension (one has to remove the DisplayWidth/Height element corresponding to the dimension that is to be cropped). |

mkver
These are just examples of cropping using MKV format tools. I don’t understand why you wrote so much.
