Yes I know...
Don't get me wrong, I kinda like AVS+, and I do use it on at least one of my Win7 notebooks. But I also have to say that it was way too much trouble to get MT mode halfway stable with my preferred plugins. I think I got it now, but my speed gain dropped to a meager 2 to 3 fps. Not really worth the effort...

I'm not using XP anymore, but one suggestion or possible thing, is for "version with XP support" just provide the "files only" version (like you did for testing), and the installer and all stuff for the "version without XP support".

Most old functions do have mmx version, which still work in 32 bit SSE-only builds. Where you may encounter significant difference between avs+ and classic avs, it's because of the low-memory scenarios. Internal frame caching is completely different, the main differences come from this fact.

On the other hand, I've seen cases in the past where compiler produced faster code from C and was optimizing better than the original hand-made assembly code.

Anyway, I added a 32bit non-SSE2 (SSE only) build to the yesterday's package.

Lil bit Errata for Layer on Wiki,

Layer

Layer (aka overlay, blend, merge) two clips of possibly different sizes, but with the same color format.

For pixel-wise transparency information, the alpha channel of an RGBA overlay_clip is used as a mask.

AVS+ Before Avisynth+ 3.4.0 Layer was working only for RGB32 and YUY2.
Filter "Overlay" was used primarily for YUV. Now Layer accepts practically all formats (no RGB24).

Also no RGB48, so no 3 channel Interleaved RGB without Alpha, supported.

Planar RGBP10 works OK
Planar RGBP12 works OK
Planar RGBP14 works OK
Planar RGBP16 works OK
Planar 32 bit Float No Alpha RGBPS OK
Planar 32 bit Float with Alpha RGBAPS OK

EDIT: Also, Maybe should throw Error if trying to use Layer on RGB24/RGB48, it just does nothing. (no change to target clip)
Sort of got S_ExLogo2() working for all colorspaces [barring YV411], no more bugs found (as yet).

I've made Layer to support rgb24/48. (by processing them as planar rgb behind the scenes)

OOooo... lovely P, will save a little bit of jumping through hoops for special cases, thanx awfully

YV12Source
ConvertTo16bit ()
ConvertToRGB48 ("Rec709")
ConvertTo8bit (dither = 1)

Does not work

Starting from YV12? Try going through planarRGB

ConvertTo16bit ()
ConvertToPlanarRGB(matrix="Rec709")
ConvertTo8bit (dither = 1)
#ConvertToRGB24 # (if packed required)

Me! And many other people here I think.
Although I have Windows 10 x64 at work, at home I have Fedora (Linux), but I still use Windows XP for pretty much everything from chatting to surfing the web and so on as long as it's not work-related.
My CPU does actually support instructions set up to AVX2 however XP supports 'till SSE4.2. The thing is that it would be a shame to drop XP Support. Is there any specific reason why it couldn't be targeted other than downloading the additional compiling tool for Visual Studio 2019 to target XP?

Is there a plan to merge the latest Expr improvements from VS?

[wonkey_monkey]

Out of curiosity, is interleaved RGB (either in AviSynth or just in general) on its way to being deprecated? Or at least sidelined by Planar RGB?

Sidelined, I would say yes.

Consider the interleaved RGB formats there for compatibility and because they - and YUY2 - were essentially grandfathered in. We're not adding new interleaved formats (save for possibly doing stuff like outputting v210 through the VfW layer, but that's not internal processing), but I can't see any reason we'd remove the ones that are already there.

Thank you very much. Recent worries have been resolved

I've examined the changes but unfortunately had no time for porting them.

Yep, I've seen the usage statistics in the latest poll over there, which was showing the demand for XP - I don't know whether it comes from the typical age tree of the visitors of forum-like social media , anyway as long as there is a relatively effortless option for building xp-friendly stuff, I'll keep it for a while.

Sidelined. And like I did in Layer, instead of supporting RGB24/48 directly and implement another set of code paths, the filter seamlessly converts them to planar RGB do the filter core and convert it back to the old format. Soon you'll even forget to put the word "planar" when mentioning RGB.

Hi P, can you confirm this please:- https://forum.doom9.org/showthread.p...54#post1899154

Limitations and Known Issues
1. VLC playback parameters are identified upon start of playback.
Therefore AviSynth script should provide video with constant resolution and fps, as well as audio with constant sample rate,
number of channels and bit-depth. Otherwise VLC will probably crash.
Need to remark that scripts with varying resolution and audio parameters are very rare.

Thanks in advance.

Windows 7 is already out of mainline support and people are still using XP? I wouldn't advocate dropping it just to spite XP users, but at this point you can barely even run Windows 7 on the latest hardware (definitely not officially supported). Encoding has to be quite painfully slow on the most recent hardware that actually supports XP.

Are there really people trying to use their ~20 year old P4 with their nearly 20 year old OS to work with modern video formats and processing techniques? Given the hardware and OS they're using it seems like they shouldn't have any issues with running an old version of AVIsynth(+) too. They should be used to it since pretty much every application has already left them behind.

Who cares, set it going and tell it to auto shutdown when done, easy peasy. [I prefer not to encode on my No1 Machine].

Not true. I just checked Asus support page, most AM4 boards support W7 and these Ryzen CPUs are very fast when it comes to encoding video.

There's a bloke here who still uses a P3.
