e97f6401de videoconvert: add additional width/height constraints 
Some of the fastpath function can only work with aligned widht/height
so make sure we check this as well when choosing a fastpath.
Add fastpath for I420/YV12 -> BGRx

22da49a55c videoconvert: also allocate temp lines in fastpath 
Some of the fastpath functions need tmplines, so make sure we allocate some in
the fastpath too.

This avoids SEGFAULTs with odd heights.

579be969e5 videoconvert: add more fastpaths 
Also reuse the I420 code for YV12 because it can handle the swapped UV fields
just fine.

10b3b88e9c videoconvert: fix handling of chroma resample 
Increase the number of temporary lines that we need, it is possible that the
up and downsampling offsets are out of phase and that we need to keep some
extra lines around. Also copy the unhandled output lines for the next round
instead of overwriting them.

ddce68a5c2 video: More video helper library improvements 
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.

6d9e76f2de video: remove intermediate Plane structure 
Remove the GstVideoPlane structure and move the fields directly into the
GstVideoInfo structure. This makes things a little easier to read and also makes
it more likely that we can pass the stride array to external libraries.
