HI Thomas, Thanks for the posting your FFmpeg code. FYI, I've had feedback from a windows users that FFmpeg turned out to be perform better than using DirectShow, so a good FFmpeg plugin might still add value under Windows.
As for the non power of two issue, this is easy to solve at the scene graph end, simply attach the ImageStream to a TextureRectangle or a Texture2D with the setResizeNonPowerOfTwoHint(false) (this only works with hardware/drivers that support NPOT textures, but that's most modern hardware these days).
