Tweak: HSV - RGB conversion difference between programs

[Wilbert]

I'm using latest v2.58, but your filter doesn't work for me:

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")

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?

[Ignus2]

Yep, it creates Y8 frames, and that's only available in 2.6

About the parameters, look in the source. It's explained at the top of the file in comments.

@Ignus2,

And why doesn't you plugin test that it has a Y8 capable host and respond appropriatly in the constructor. It's really bad form to wait until the first frame is rendered to fall apart at the seams.

You chose to violate the API, its your job to validate your extensions.

[Ignus2]

I don't care who or what I violate, there's the source, go ahead and fix it, if it's annoying you that much.

If you have questions about using the plugin, I'll gladly answer them.

Just don't complain please.

Made some minor fixes.

I removed the earlier attachment, here is the new one.

just to throw a spanner in, generally Red is at 122 degrees. ie, on a 601 vectorscope it will sit there, and on most colour correctors this is the angle you push the joyballs to go toward red.

[Ignus2]

What do you mean by "generally"?
As you can see, I have found as many variations of this, as there are places it is mentioned at
