Madshi.I did find the switch but didn't solve my problem.Ffdshow connects nicely with MadVR if I use ffdshow to decode my H264 movies but when I try to use CoreAVC for decoding, ffdshow doesn't want to connect anymore...(Ffdshow settings are inputting and outputting YV12, so that shouldn't be the problem).Also my Coreavc settings should be correct.

@VHT
Have you set ffdshow video / Codecs / Raw video = all supported ? If the CoreAVC output color space doesn't match ffdshow allowed input color spaces, ffdshow doesn't enter the graph (as post-processor) |

Can't tell you why. Please try with madVR 0.4. If that still fails, I'd need a sample or something, so that I can reproduce the problem on my PC. |

madVR 0.4 released
http://madshi.net/madVR.zip Code:
* modified (improved?) initialization order * fixed: aspect ratio was incorrect with some sources * added Lanczos8 resampling option (but I don't recommend to use it) * changed the way the GPU textures are updated Unless new show stopper bugs show up, this will probably be the last release for this weekend. |

There are also similar, commercial calibration test disc from Bürosch, AVIA and Digital Video Essentials. Dunno about free alternatives, tho... |

In terms of chroma upsampling I have no real world example. Maybe some Pixar movies would have sensitive scenes, but I think I would really have problems noticing the differences. But in terms of luma scaling I have a few movies which show a visible difference between Lanczos3 and Lanczos10. These movies have very high frequency response and suffer from quite a bit aliasing. With more taps there is very slightly more detail and much less aliasing. The german DVD of "My Fair Lady" is a good example. Maybe some Superbits with aliasing on the disc (e.g. "The 5th Element") could also benefit from more taps. And btw., additional ringing by the scaling algorithm is no problem even with such high frequency material. |

.4 build
* madVR is now pickup up my LG37 (HDTV) refresh of 24Hz properly. * Reclock tearing test shows *no* tearing now with 23.976@24Hz playback on *secondary* (LG37) Movie_frame_interval = 41.71 Avg GPU rendering = 19.67 Excellent work! |

Very cool! Which license do these pictures come with? Would it be legal to include them in madVR somehow?
Which scaling algorithms would you like to have? The same used for luma scaling? Or a subset? Quote:

So is CPU consumption on secondary display ok now, too? No more 100%? That would fall under the "smooth playback" category which is not implemented yet. So I can't give you any comment on that... |

Do you have DVD examples on which additional ringing is visible in a movie? I mean scenes inside the movie and not the fonts at the ending? If this discussion is too off topic I would be thankful for a short PM. |

For HD material (1080P-M2TS AVCHD), CPU util is around 55%, using MPC-HC internal decoders. |

the start credits of Shoot'em Up on BD are very good to spot dodgy chroma processing(the big SHOOT/EM/UP logos written in blood)...but apart from these extreme examples, any red object should do(there's a woman w/ a strongly saturated red coat in "Night at the Museum")

I'm very concerned about chroma(being colorblind and all), I let you guys take care of luma then Last edited by leeperry; 13th April 2009 at 16:27. |

Hi madshi,
thanks for the new renderer. Just playing around with it. Currently I do get lots of heavy stutter in ZoomPlayer when using the renderer though. (on secondary display with reclock) I am on a ATI radeon 4550 with 512MB of memory. I guess that card is not powerful enough, right ? I also tried disabling all quality settings but that did not change much. CPU utilisation is below 40% on a DualCore CPU and the Haali renderer works fine so I guess the videocard is the problem, right ? Are there any baselines what GPU is the minimum for stutterfree 1080p playback ? Bye, Alex |

Hi all,
Just a thought. Would madshi and beliyaal consider teaming up to integrate beliyaal's work on reducing judder, syncing frames etc, with the excellent levels conversion and more, work by madshi. I am torn between which renderer I want to use but would love to see madVR with the frame sync stuff from beliyaal if possible to combine both. It would be a terrible waste of time for madshi to spend lots of time on audio / video sync if its possible to use the existing work by beliyaal. Cheers, |

As of 0.4, everything works great on my end. No CPU usage penalty, and I get smooth playback with Bicubuic -0.75 (anything higher introduces stutter in 1080p material). And all of this on a lowly Radeon HD3650. Great job.

madshi
Can you add support for loading subtitles anytime soon or this is too much of work for now? I really want watch some movies with MPC-HC/madVR but i prefer to watch with subtitles coz English is not my native language. "Use VobSub" is not the solution. |
