Crop/Resize

[Selur]

Okay, this is not a Hybrid bug, but a bug in one of the filters or Vapoursynth itself.
when I use:

# Imports
import vapoursynth as vs
core = vs.get_core()
# Loading Plugins
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/Support/fmtconv.dll")
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/vslsmashsource.dll")
# source: 'F:\TestClips&Co\files\YUV\yuv422_16bitBitEndianStereo.mov'
# current color space: YUV422P8, bit depth: 0, resolution: 848x352, fps: 23.976, color matrix: 709, yuv luminance scale: limited, scanorder: progressive
# Loading F:\TestClips&Co\files\YUV\yuv422_16bitBitEndianStereo.mov using LWLibavSource
clip = core.lsmas.LWLibavSource(source="F:/TestClips&Co/files/YUV/yuv422_16bitBitEndianStereo.mov", format="YUV422P8", cache=0, prefer_hw=0)
# making sure input color matrix is set as 709
clip = core.resize.Point(clip, matrix_in_s="709",range_s="limited")
# making sure frame rate is set to 23.976
clip = core.std.AssumeFPS(clip=clip, fpsnum=24000, fpsden=1001)
# Setting color range to TV (limited) range.
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)
original = clip
# cropping the video to 842x348
clip = core.std.CropRel(clip=clip, left=0, right=6, top=2, bottom=2)
# cropping the video to 842x348
original = core.std.CropRel(clip=original, left=0, right=6, top=2, bottom=2)
clip = core.fmtc.resample(clip=clip, kernel="spline16", w=1280, h=530, interlaced=False, interlacedd=False)
original = core.fmtc.resample(clip=original, kernel="spline16", w=1280, h=530, interlaced=False, interlacedd=False)
# adjusting output color from: YUV422P16 to YUV420P8 for x264Model (i420@8-bit)
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P8, range_s="limited")
# adjusting for FilterView
if original.format.id != clip.format.id:
if (original.format.color_family == vs.RGB and clip.format.color_family != vs.RGB):
   original = core.resize.Bicubic(original, format=clip.format.id, matrix_s="470bg", range_s="limited")
elif (original.format.color_family == clip.format.color_family):
   original = core.resize.Bicubic(original, format=clip.format.id, range_s="limited")
else:
   original = core.resize.Bicubic(original, format=clip.format.id, matrix_in_s="470bg", range_s="limited")
stacked = core.std.StackHorizontal([original,clip])
# set output frame rate to 23.976fps
stacked = core.std.AssumeFPS(clip=stacked, fpsnum=24000, fpsden=1001)
# Output
stacked.set_output()

and

it randomly crashes,... every few times,.. -> I'll so some more testing and if I can't identify the culprit I'll try to contact the Vapoursynth authors over at doom9s.

Okay, it's definitly the resizing, without:

clip = core.fmtc.resample(clip=clip, kernel="spline16", w=1280, h=530, interlaced=False, interlacedd=False)
original = core.fmtc.resample(clip=original, kernel="spline16", w=1280, h=530, interlaced=False, interlacedd=False)

the script works fine.
-> I'll try to contact the fmtc author. (https://forum.doom9.org/showthread.php?p=1927388)
