954db90918 videotestsrc: fix undefined behaviour of left-shift
With a small type for the color values being left-shifted, the result is
undefined and it could potentially overflow.

27d4061c6c videotestsrc: add support for I420_10 format
Add support for the I420_10 formats
Use the video frame api to get pixels and strides instead of our own
custom versions. Fixes the YVU9 format and probably some others.

d8f698fe20 x-raw-bayer -> x-bayer

but for now keep the x-raw namespace clean.

aa7ee3733d videotestsrc: fix YV12 chroma plane confusion
GST_VIDEO_FRAME_PLANE_DATA() returns the data for the n-th plane,
not the n-th component. In this case, the chroma planes are swapped.

9ad89374a3 video: add colorimetry info
Make enums for the chroma siting for easier use in the videoinfo.
Make enums for the color range, color matrix, transfer function and the
color primaries. Add these values to the video info structure in a Colorimetry
structure. These values define the exact colors and are needed to perform
correct colorspace conversion. Use a couple of predefined colorimetry specs
because in practice only a few combinations are in use.
Add view_id to the video frames to identify the view this frame represents in
multiview video.
Remove old gst_video_parse_caps_framerate, use the videoinfo for this.
Port elements to new colorimetry info.
Remove deprecated colorspace property from videotestsrc.

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.

08be25ce62 videotestsrc: Various improvements
Replace moving-color-bars pattern with smpte100, and change
moving-speed to horizontal-speed.  Default is now 0.  Add
a rotation stage to pattern building.
Allocate a temporary scanline for building images.  Remove
unused code.  Disable several patterns that we're unable to
test and probably never used.  Add other variants of bayer
sampling.  Convert some patterns to use videotestsrc_blend_line.

use foreground-color/background-color instead of white/black.
