Problem in Stride Calculation #68

Closed shakirbsm closed 3 years ago

shakirbsm commented 3 years ago

I found this project helpful and interesting, however while encoding videos from images i have found a problem that my animation was somehow translated in such a way that it seems to be a parallelogram with upper left somewhere in middle. After some debugging i found out that it might be problem with stride calculation. I have images with following details: Width: 1890 Pixels Height: 1512 Pixels PixelFormat: 24bppRgb Stride from ImageData = 5670 whereas from my calculation of stride it should be 5672 I have calculated stride with following formula as given in msdn forums Stride = 4 (Bitmap.Width BitsPerPixel + 31)/32)

I've just fixed it in the v4.0.1 release.
