AWarpSharp2 for VapourSynth

[jackoneill]

As requested, a port of AWarpSharp2: https://github.com/dubhater/vapoursynth-awarpsharp2

The output is not 100% the same as the Avisynth plugin's, due to some differences in the way the margins are processed. If you crop away six pixels from the left and the right, then maybe the output will be identical. Then again maybe not, because I didn't bother writing any SSSE3 code.

The "chroma" parameter is a bit different now. There are also two new parameters, "planes" and "opt". It's all explained in readme.rst.

I merged the "aWarp" and "aWarp4" filters. There was really no reason to have a separate filter for the supersampled thing.

The "aWarpSharp" filter only existed for compatibility with old Avisynth scripts. That's not relevant here, so there is no such filter in this plugin.

Dude, I love u.

I love u.too

So we can assume this would be slower than the avisynth version?

Oh, and thanks by the way ;)

I don't know. Compare them? (Don't forget about the threads.)

Thanks a lot. One of my favourite plugins with BM3D.

Not sure if entirely relevant to this thread, but since the a 64 bit version has been done, what are the chances of 64 bit version for Avisynth+?

or maybe its just a perfect time to switch to vaporsynth

[ryrynz]

It still can't do real time post processing yet can it? I believe ffdshow raw and Avisynth is still the only option until madVR adds support.

From me, very low. Maybe ask in the Avisynth+ thread.

Would it ever support >8bit clips?

Who knows.

[jackoneill]

Who knows.

Make that a "yes".

The only notable change is the 16 bit support.

I am having real trouble getting awarpsharp to load, all 64bit vs, definitely 64 bit libawarpsharp2.dll in plugins64. says no attribute with name warp exists. I have no trouble with any other plugins, qtgmc, fmtc, bm3d etc. any ideas? cheers Divxmaster

Load it manually so you'll get an error message:

core.std.LoadPlugin("B:/your/path/here/libawarpsharp2.dll")

[divxmaster]

Ah, requires API 3.4, I'm currently on 3.2.
Thanks for the tip on LoadPlugin showing errors, vs autoload that supresses errors, that's useful to know.
edit: For those that want to know, Vapoursynth R30 or newer needed for API 3.4.

Cheers,
Divxmaster

I think I found a bug. With AWarpSharp2 (did not test others), > 8 bit input, chroma=0, and planes=[1,2] (or 1 or 2, i.e. luma not processed for output), the output is garbled, with half the screen being totally wrong.

btw for bug reports in general do you prefer a notice here or on Github? Thanks, anyway. Really appreciate the work.

v3 fixes the bug. (https://github.com/dubhater/vapoursynth-awarpsharp2/releases/tag/v3)

I prefer Github, if you have an account there. If not, this is fine too.

v4 is here. (https://github.com/dubhater/vapoursynth-awarpsharp2/releases/tag/v4)


* Add parameter "cplace". Valid values: "mpeg1" and "mpeg2". Default: "mpeg1", same as in previous versions.
* Make the "depth" parameter an array so the depth can be set independently for each channel.
