Yes, in LAV. And no, that has nothing to do with LAV's future.

I see... BTW, don't get me wrong, I do want to see deband in LAV at some point, its just the one in ffdshow doesn't deserves to be in LAV cause of his poor quality and occasional brokenness.

nev,
this is a capture I've just made from my local cable TV.
http://www.mediafire.com/?2ub8kb1pdtlbt5f
It shows a problem with the field order which happens from time to time.
From what I see the first part is BFF while the end (and the usual for our PAL country) is TFF. It's just this news story (and rarely others like it) that is inverted.
I can manually fix by changing TFF or BFF but sadly its not very convenient and I was hoping the decoder can sense this and act accordingly.
Is there any hope or I should forget about it and simply blame the producers/broadcasters for this mess?

Edit:
Or could it be that the DVB App that I'm using (DVBViewer) messed it up?

If the auto fieldorder setting doesnt work, then there isnt much hope.

The one in ffdshow is the one in avfilter. What brokenness? Don't blame avfilter when gcc breaks

BTW, what's the best deband filter out there? Speed?

But why deband is always the 1st thing that breaks and many other things continue to work as always? Or this is the only gcc-compiled part in ffdshow?

I don't think I tried all possible solutions but what I personally like is flash3kyuu (f3kdb), which is more optimised, available for 32 and 64 bit, supports up to 16bit bitdepth (input and output), has dithering to go from higher to lower bitdepth and gives visually much nicer results. EDIT: full-chroma colorspaces probably supported too, didn't actually tried

Always? Sounds like deband is completely broken . After I changed it to use avfilter's code instead of the old, slow and non x64 friendly code there have been no issues except this one and it was caused by gcc, not by the code itself.

Why deband? You have to ask that question to the gcc devs, there was a bug that was triggered by something in gradfun's code and not by anything else. Everything ffmpeg related is compiled with gcc in Windows (LAV, ffdshow, madVR...). x264 has suffered gcc bugs in the past too.

Are you also planning to support frame doubling/smooth video for 1080p23,976 content in the future?

I suppose it could be a channel problem (neither cable provider problem nor DVBViewer/LAV problem). I see sometimes such problem even on analog TV.

We could always hope for Avisynth support I guess.
Would that be much work to implement? Then it would be bye bye ffdshow

I'm not sure what nevcairiel uses, but madVR is a mixture of MSVC++ and Delphi compiled exe/dll files. I'm not using gcc at all, except for creating the external ffmpeg dlls.

Same here, only the ffmpeg dlls are compiled with GCC, libbluray and LAV itself are compiled with MSVC2010, but i think thats what he meant.

It read to me as if he meant LAV and madVR themselves would be compiled with GCC, too. But that could have been a misunderstanding on my part. Anyway...

You can always use ffdshow post processing with avsynth for that.

I did try that because I was curious but I really don't think nev should bother implementing that in LAV, it butchers films and not that many people want it.
There are a lot of TVs that do it much better than software implementations anyway.

I was obviously talking about the ffmpeg dlls that all of them use.

Well, at least LAV is very much "ffmpeg related", too, seeing that in its core it's basically a DirectShow wrapper around ffmpeg/libav, so what you said was not that obvious. Anyway, doesn't matter, it's cleared up now.

madVR is the same after all. You're the only one that knows what the hell is a decoder doing inside a DirectShow video renderer after all that talk about the correct place of putting things
