I'm using latest v2.58, but your filter doesn't work for me:
Code:
LoadCPlugin("F:\Plugins3\Colordiff\colordiff\colordiff.dll")
ImageSource("F:\Plugins3\Colordiff\colordiff\linuXP.jpg").ConvertToRGB32()
ColorDiff(c1=100, c2=100, c3=100, w1=2.0, w2=2.0, w3=2.0, colorspace="RGB")
Code:
LoadCPlugin("F:\Plugins3\Colordiff\colordiff\colordiff.dll")
ImageSource("F:\Plugins3\Colordiff\colordiff\linuXP.jpg").ConvertToYUY2()
ColorDiff(c1=100, c2=100, c3=100, w1=2.0, w2=2.0, w3=2.0, colorspace="YUV").ConvertToYUY2()
In both cases I get no image, and the following error message: Filter attempted to create VideoFrame with invalid pixel_type.
Btw, what do the cj and wj parameters do?
