In certain cases one could want to implement a video buffer pool that allocate
each plane separately. The problem is that figuring-out correct plane sizes
from a GstVideoInfo is not really possible. Though, it's really easy to
calculate it when filling up plane information inside video info
implementation. A known use case is the gl buffer pool and memory. For the gl
upload uses case, it uses one malloced buffer per plane to download/upload
from/to the textures. Keeping these on sync. When comes time to allocate the
plane, it current uses video info offset differences to figure-out the size.
The problems starts when we try to implement GstVideoAlignment. After running
gst_video_info_align(), the offset technique to deduce the plane sizes does not
work any-more.
