Should work just fine with v0.4, as long as you don't move the media player window to another monitor after playback has already started. That needs some work, but it's not top priority for me. Just make sure you start playback on the monitor you want to watch on. Quote:
However, I have on my to do list to offer CSC via shader math as an option for those (probably many) people who do not want/need to do gamut correction. Not sure whether I'll offer gamma correction via 1D LUTs then, though, cause I don't like having 100 different code paths. I'll probably only offer either CSC via shaders and no gamut/gamma correction at all. Or the full deal with a monstrous 3D LUT, which will offer all the calibration/correction power we could ever dream of. Quote:

Actually the 3D LUT processing doesn't cost much performance at all. I've just checked: If I simply skip the 3D LUT (and thus display YCbCr without converting it to RGB), rendering one 1080p24 frame takes about 15.5ms on my ATI HD3850 graphics card. If I enable 3D LUT processing, it takes 17ms.

but I think most displays will convert again to RGB internally, and w/ much worse results than yours anyway.. Last edited by leeperry; 15th April 2009 at 13:48. |

I imagined the LUT would be faster also. madshi, just want to tell you about a huge lut I made use of during a uni project. I am wondering how much memory does your lut table take up. Maybe it could be optimized like I did for this project I talk of.
The lut I worked on was a 7 dimension array of 0-51 possibilities, of 7 poker card values actually (0-51 as possible values for each card) with each combination in the array pointing to a ranking between 0 and 7142. (It turns out surprisingly that thats the amount of 5 card texas holdem possibilities there are possible from 7 cards). You can image a 7^52 array would have been MASSIVE, like hundreds of gigabytes. I used a pruning technique I found on a maths forum specific to this to reduce the size, where after the second or third card (2nd or 3rd dimension in the array) various combinations of those 3 values would point to an equivalent future. (eg, AKQJT of hearts always shares the same final value as AKQJT of clubs, no matter what the last two cards are. It took a large loop, and the use of the original massive array to figure out which early dimensions ALWAYS follow the same path to a final value and generate the pruned array (actually 7 smaller arrays, each one a different size depending on futures at each stage instead of one giant one). I hope I have made this clear, and hope it can help somehow. I am not sure how this could be applied exactly to this color levels conversion / gamut conversion case but something I wouldn't mind looking into if you think it might help. For my poker project it ended up going from hundreds of megabytes, down to something that could fit in a mobile phones memory and executed MUCH faster than the original massive array because most of the array could be fit in the cpu's inner cache. What sort of dimensions is the LUT you are dealing with and whats the final size in mb? Last edited by mark0077; 15th April 2009 at 13:54. |

If madVR employed shaders to do the conversion, that would be just Haali Render clone in effect Colour Gamuts conversion may be very much of use per se as well, as there're different LCD monitors now available, including those which colour gamut widely exceeds sRGB standard, for instance LED-backlight displays (upto 120% of NTSC gamut). They are rare nowdays but certainly going to become much more popular when technology evolves.

DVD navigation should be a must. I realize this renderer is in its infancy, but selecting a VOB is a pain in the butt. For everyday use this has no WAF. It does not play from one VOB to the next, it stops playing at the end of the file and you need to select the next to continue.
The picture looks great and I thank Madishi for his efforts. As he has stated, he has his priorities. Basic playback capabilities will put this as MY number one renderer. I think that the more user friendly it becomes, the more people will use it. Right now it has potential, but without navigation from within the disc it is very limited in its use. Thanks for everyone's support and help. MAK |

leeperry, et. al.: What is this powerstrip search engine you guys are talking about? I can't find a reference to it anywhere else except doom9!
EDIT: Oh, I think I found it (had to use google): From a post about powerstrip 3.80 back in june 2008: Quote:

make sure to run it w/ your display turned off as it cycles refresh rates very quickly and might very well make it go up in smoke |

try KMPlayer, enable "seamless playback", open the first VOB and it will play all of them in a row seamlessly. if that feature was in MPC, I would drop KMP instantly and there's also an option to do this w/ ALL the videos within the same folder, so it looks like this : that's 114 720p WMV files opened seamlessly(no gap, acts as if it were one single file)...so opening 5 VOB files in a row is like child's play I wish so much that madshi would allow us to fake the GUID of mVR via the .ini file, so we could use it in KMP Last edited by leeperry; 15th April 2009 at 18:03. |

Yes. And as I already researched that issue (LED LCD panels etc) I'm already aware about downside -- due to increased gamut the clear colour gradients become even worse than on typical LCD panels. I.e. the colour span is wider but in current ubiquitous RGB32 just 8bit may not be enough to represent a gradient artifact-free (this of more importance to anime content of course). That's where madVR comes into play If only the producers understood that 10bit is good (and some AVC profiles like High10 actually support 10bit...)

Thanks for the heads up on this, but unfortunately, searching for the starting VOB within the disk is not going to cut it for the family. Casino Royal has about 100 VOB files. Which one to choose??? Maybe KMPlayer can choose the correct one... I will look into the player. On another note is calibration disc usage to set primary and secondaries on my Marquee 9500 is tiresome. No way to navigate through the disc. PGCC from the AVS forum does the same thing as the LUT file in this program. Once again, thanks for the information and knowledge.. Just my .02. MAK |

@racerxnet: open those that are 1GB in a row, that's the movie! but no subs w/o menus I think |
