I've found one situation where going back to the menu just plain doesn't work when using either MPC's internal MPEG2 decoder or ffdshow, and that would be when you're looking at a self-playing image gallery/slide show (as is often included as an extra on DVDs) and hit "title menu" right after the image has changed. What I found was that the timestamp generated (by Microsoft's DVD navigator, I assume) for the menu image then is before the last timestamp generated for the still image, so the menu image isn't shown by the renderer - but that happens with MPC's internal MPEG2 decoder as well. Hitting "title menu" a second time helps in that case. (To reproduce: watch a slide show, drop down the "Navigate" menu, and click on "Title menu" as soon as the image changes. Chances are that you won't be seeing the menu...) Quote:

free-codecs.com is not maintained by ffdshow-tryouts team. If you want to have bleeding edge builds, use www.ffdshow.info instead.
Also, it shouldn't matter whether the build is compiled with SSE or not since the code is already hand optimized for mmx, sse and sse2. |

2 Bugfixes for my AviSynth patch:
* Fix crashes caused by still uninitialized buffer variables when AviSynth filter instances requested frames right after being created (TIVTC, I'm talking about you... ) * fix bogus timestamps right after flushing/seeking Download Patch (against rev. 1126) The filter should be feature complete now, but due to me hunting the above bugs the documentation is still to be written... :/ NB: That build contains drevil_xxl's SSE3 additions, so if anything is acting wonky try it with SSE3/SSSE3 on the "Info & debug" page disabled... np: Pole - Streit (2)

Thanks Leak, it's working nicely now!
There is already a fairly good mod of Dscaler5 aimed to do IVTC on HD (and SD) content, but unfortunately it only works for film, it's no good for anime (unless it was originally animated using cels, and those shows are few and far between now.) |

The only problem with regard to anime I could think of would be that it discarded the first found duplicate instead of a frame of the longest duplicate chain, but that shouldn't be hard to add to said mod... Or do you mean it's not handling hybrid (24/30 FPS) material well? np: Pole - Raum 2 Variation (Kit Clayton) (R)

The detection algorithm was done to work with 24fps film and it simply doesn't work with the problematic cadence of digitally rendered anime. It's possible that it's an easy fix, but I'm not smart enough to figure something like that out.

Okay, I'm not going to tackle writing docs at this late an hour, but I had another idea - I guess I could pass the current aspect ratio into AviSynth as a global variable which is read back after the script has been compiled to get a new aspect ratio for the resulting images.
That way, a script could dynamically detect whether it's fed 4:3 or 16:9 video (as the script already gets recompiled when either the frame size or the aspect ratio changes) and adjust it's output... either size the images to 800x600 directly for 4:3 material or resize it to 852x480, crop off 26 pixels at the left and right and add a 60 pixel border above and below for 16:9 material, with a 4:3 output aspect ratio in any case - just the right size for my 800x600 projector... (Yeah, it's a bit cumbersome to do stuff like that using the ternary "? :" operator in AviSynth, but it's doable...) np: Atom - On the Edge of Fidelity (Replicant Rumba Rockers (remixed by Burnt Friedman))

And for me, the first menu item ("PLAY") is always highlighted when the menu of my Ghost In The Shell: Stand Alone Complex vol. 1 DVD starts up...

I mean only mpeg2 decoder from cyberlink, rest of graph exactly the same as when using ffdshow (dvd navigator from ms is used).
Anyway static menus doesn't work at all, something is wrong in ffdshow. Here is example ffdshow: cyberlink: Probably when this will be fixed animated menus will fix also. |

Well, I guess I wrote this several times above, but let me reiterate:
* DVD menus are done via DVD subtitles * ffdshow always overlays the current DVD subtitles on the frames it produces * Static menus don't (continually) produce any frames after the first * Thus, ffdshow has nothing to overlay changed subtitles/highlights on * Maybe highlighting on animated menus doesn't work if it's there from the very first frame, but the animated menus I know where the first highlight appears once the menu has settled down definitely do work ffdshow would need to buffer the last frame and produce new frames with new timestamps when the subtitles change, but it doesn't do that yet; and to be honest ffdshow's subtitle filter/handling is waaay over my head...

*phew*
It only took me half of this afternoon, but I managed to craft a help page for my patch... It's not hooked up inside ffdshow itself yet, so there's no new build to download, but could you guys please have a look at it and comment on it and suggest improvements? np: Pole - Paula (1)

Now I know what AviSynth actually is... *me blushes, runs away, and hides* Edit: If you still have the nerves you could replace the ampersands & in the URLs with &. That should make it XHTML-compliant. Thanks! Last edited by fastplayer; 2nd May 2007 at 20:53. |
