Make a new GstVideoFormatinfo structure that contains the specific information related to a format such as the number of planes, components, subsampling, pixel stride etc. The result is that we are now able to introduce the concept of components again in the API. Use tables to specify the formats and its properties. Use macros to get information about the video format description. Move code to set strides, offsets and size into one function. Remove methods that are not handled with the structures. Add methods to retrieve pointers and strides to the components in the video.
