Vapoursynth

[Myrsloik]

R34 released. Post about stuff. Finally got everything tested. Use the donation button so you can say you've contributed to real donationware!

Changes:

r34:
avfs can now output the same high bitdepth formats for avisynth+ as for vapoursynth
it's now possible to skip installing the visual studio runtimes in the installer to reduce online dependency of installer (installation may not work until manually installed, obviously)
temporalsoften plugin is no longer included in the windows installer, it has been replaced by the misc plugin containing various functions useful for avisynth compatibility
the default max memory usage is now 4GB on 64bit systems
fixed several unpacking issues in avisource introduced in the previous version
added warning if there are any nodes or frames still in use when the core is freed
improved avfs prefetch logic for vpy
added premultiplied blending mode to maskedmerge
added premultiply filter to premultiply a clip with alpha
makediff and adddiff no longer pointlessly clamp float to a limited range since there's no good reason to do so
fixed memory leak when the core is freed introduced in the previous version
fixed memory leak in avfs introduced in the previous version
removed rshift and replaced it with a scale argument in sobel and prewitt
fixed sobel and prewitt wrongly passing through the input pixel values
added support for hdr formats and dci-p3 in zimg
optimized planestats
added float support to pemverifier
fixes active region offset and height for interlaced resizing
added support for more different subsampled input formats for vfm (jackoneill)

GenericFilters is no longer included because the core functions plus the TCanny plugin can now replace 99% of its uses

i want to use GBlur,2.83 in R34

what is alternative for that at same strength?

& thanks again

It should be about the same I guess? I haven't really compared the details and it's a better question for the TCanny author. Or just experiment until it looks the same. That's rarely wrong.

how do you unmount the script in the new version?

EDIT: ok I figured that the file unmount itself when I close the cmd window.

other problems I have, there're no check on the files that you're going to mount, I can type in whatever filename at the end of the cmd and the program will still sees it as a file and mounted it.

And I have a video file that gives me garble images after mount, which it has not happen before.

What's the output format of the images and what do you try to open them with?

The output format YV12 in avi container. The script previewed normal in the vapoursynth editor, but when I open it with Adobe Premiere or Virutaldub after mount, they all give me garble images. I tried mounting different video files with the same script and they were all fine.

Can you cut a sample that reproduces it or take a screenshot of the garbled output?

Simply use:

res = core.tcanny.TCanny(src,sigma=2.83,mode=-1)

Okay after more testings, I found out that the problem came from the cropRel function in my script

clip = core.std.CropRel(clip, left=12, top=0, right=10, bottom=10)

clip = core.std.CropRel(clip, left=12, top=0, right=12, bottom=12)

The top one gives my garbage image after mount, the bottom one works fine

Is it because of mod4/mod8/mod16 issue?

I believe for the top one you get a video with width or height not divisible by 4, which may be problematic in certain cases.

That is kinda odd. I can reproduce it but I have no idea why it happens. Oddly enough mpc-hc seems to play the file right. That makes it even weirder.

R35-RC1

Should fix the avfs issues. Report any other bugs you find.

r35:
fixed avfs frame packing so it matches vfw behavior
fixed one frame leak on script reload in avfs
fixed 8bit 3x3 convolution where the upper left pixel wouldn't be taken into account correctly on x86

[lansing]

yes problem fixed, thanks

R35 released. Same changes as for RC1 a few posts up. Now we're back to regular stable maintenance releases again I guess since AVFS, optimizations and other big refactoring has been tested now.

Got an invalid syntax error and I'm not sure what I'm doing wrong,..
(I'm on Ubuntu 14.04)

trying to load:

# Imports
import os
import sys
import vapoursynth as vs
core = vs.get_core()
# Import scripts folder
scriptPath = '/usr/lib/python3/dist-packages'
sys.path.append(os.path.abspath(scriptPath))
# Import scripts
import vs-havsfunc as havsfunc
# Loading /home/selur/Desktop/Test-AC3-5.1.avi using LWLibavSource
clip = core.lsmas.LWLibavSource(source="/home/selur/Desktop/Test-AC3-5.1.avi", cache=0)
# stabilizing using Stab
clip = havsfunc.Stab(clp=clip)
# Output
clip.set_output()

I get:

Failed to evaluate the script:
Python exception: invalid syntax (test.vpy, line 10)
Traceback (most recent call last):
  File "src/cython/vapoursynth.pyx", line 1490, in vapoursynth.vpy_evaluateScript (src/cython/vapoursynth.c:26958)
  File "/home/selur/Desktop/test.vpy", line 10
    import vs-havsfunc as havsfunc
             ^
SyntaxError: invalid syntax

havsfunc is present inside '/usr/lib/python3/dist-packages/vs-havsfunc.py'

-> How would I properly load the havsfunc script?

The problem is you are using a dash character in the module's name. Why?

Convert it to an underscore or even better, use the original name.

[Selur]

got the script from a ppa where the dash was inside the name.
Thanks for the info.

Feature request: native support for OpenCL platform.




Really, it's not a joke.

[Selur]

native support for OpenCL platform.

What OpenCL support is there aside from native?
