The behavior for zero AVEncMPVGOPSize value would be varying depending on GPU vendor implementation and some GPU will produce keyframe only once at the beginning of encoding. That's unlikely expected result for users. To make this property behave consistently among various GPUs, this commit will change default value of "gop-size" property to -1 which means "auto". When "gop-size" is unspecified, then mfvideoenc will calculate GOP size based on framerate like that of our x264enc implementation.
