The patch is not finished as you can read from the link above. The patch enables multithreading on all encodes (as far as I have tested).

Leak,
Thanks for clarifying my "bug". It makes sense.

[foxyshadis]

Can you hook onblur() from the filter menu or one of the other teardown messages, to pop up a 'save me?' box? I haven't worked with the side menu at all, I have no idea what's possible.

Same here, but after a quick check I couldn't find anything that would get called specifically when the page is changed.

And TBH, if you're editing a bigger script you'll probably be happier with doing it in an external text editor anyway. Or just don't forget to hit "Apply" after changing or pasting in the script.

np: Burnt Friedman - Machine In The Ghost (ft. Barbara Panther) (First Night Forever)

EDIT: That's a problem with regedit, actually - the scripts are written to the file with their linebreaks intact, so regedit's parser will just skip what it thinks are broken lines.

But if you just export the whole ffdshow configuration from regedit, it'll produce the exact same problem...

I'm not sure about complex scripts,but the simple ones can be writen in one line and then there is no problem with exporting and importing.

Example:
ColorMatrix(mode="Rec.709->Rec.601").SeparateFields().fft3dfilter().LanczosResize(640,480).Weave()

When is the next beta planned for?

Not very near, I think. We have some issues to fix.
I'm implementing RGB<->YUV conversion options.

Not before PAFF and h.264 multithreaded for all x264 encodes.
Maybe E-AC3 decoder should be added and dts issue fixed.

These are exactly the Updates most people need !

What do you think, when will there be a EAC3 Decoder build ?

Just the PC vs rec levels option or also the custom matrix?

[haruhiko_yamagata]

More than just the PC vs rec levels, less than the custom matrix.
Black cutoff, white cutoff, chroma cutoff as well as ITUR-BT.601/701 are configurable.

the 64bit builds seem to be unable to decode flac audio, could someone look into this and see why it doesn't work?

[Shakey_Jake33]

Even with the 32-bit build, I've never been able to get ffdshow to decode standalone FLAC files.

Without a parser, it can't AFAIK.

Maybe not standalones, perhaps that is where the problem is.
I've played a lot of multichannel flacs in mkv containers and had ffdshow transcode them to ac3 and everything, all without issues. (32bit build).
I might digg one up and try it with 64bit and see what happens.

edit: ok I can confirm decoding works for flac in 64bit, as long as they are in a container.

One interesting observation: With Vista, 8600GT, 163.69driver, latest ffdshow from clsid and EVR-Renderer: I can sharpen with the sharpening of the drivers and can sharpen in parallel ffdshow. To my eyes it looks extremely good, potentially even better than limitedsharpening (I watch at 1920*1080 on a 4.2m wide and 2.2 high screen with a sony ruby)...less artifacts than anything else I tried...

...interesting: as soon as I enable lanzos resizing, the sharpening through the nvidia-drivers is broken...if I let the card do the resizing, sharpening works in ffdshow and in the card.

Before I started with limitedshaprening, I used to use lanzos resizing with some sharpening in ffdshow. I have tested this against the current resizing and sharpning of nvidia. In this case nvidia looks better than ffdshow...quite impressive.

@haruhiko_yamagata:
The font size is not compatible with vsfilter, at least horizontal scale after rev1482.

I've got a NON-Square pixel AVC encode, when subtitle with ffdshow(after rev1482), the renderer automatic adjust the font size for the subtitle. but with vsfilter, it won't.

Great feature, though not compatible with vsfilter(opposite to the changelog), I like it.

HuffVUV encoding seems to be broken in some current "tryout" builds. I used ffdshow with HuffYUV-YV12 and different settings to capture a desktop area with some screen recorder. Resolution: 1016x680 pixel, or similar dimensions.

The screen recorder used to crash after a while.

Watching a shorter video I completed before a crash, I saw that the bottom of the video contains some completely garbled lines with "fantastic colors", they grew upwards over the time the video played.

PAFF is already implemented in ffmpeg/libavcodec? Since when?

Also I'd like to repeat my very big feature request. It's letterboxing for DVD. Or at least it would be nice, if I could move the subtitles. Is someone willing to have a look at it? We've been already discussing this before, unfortunately this is still not implemented. I think with some work on VobSub, this might be implemented.

Also on the codecs tab under MPEG-2 it still says DVD Decoding (not working yet). Why? Are there any known problems? It works fine for me already for a long time (except for the letterboxing ;-) ). And I think MPEG-2/DVD support should be turned on by default.
