I420 is YUV bt.601 8 bits per channel with 420 subsampling.
I010 is YUV bt.601 10 bits per channel with 420 subsampling.
I is color space - bt.601. The function does no color space
conversion so H420ToI010 is aliased to this function as well.
0 = 420 subsampling. The chroma channels are half width / height.

When developing WebRTC applications with custom video sources, libyuv's
API is often the required part of the project. For that, application
developers can link with a separate standalone instance of libyuv.
However, it is even better to avoid that binary code duplication and
link against libyuv as a part compiled into the WebRTC library.
When building WebRTC as a static library target, the symbols from libyuv
are normally accessible to the linker without any extra actions. When
building WebRTC as a shared library, that does not work as the exported
symbols are those marked as visible, while libyuv is built with the
hidden visibility setting by default.
This patch adds an extra flag to enable switching the symbol visibility
to default when building shared library targets depending on libyuv in
WebRTC and Chromium projects. By default the flag is not enabled,
preserving the prior behaviour.

Using public_configs, client projects must rely on public_deps to
propagate configurations up in the build graph. This is bad because
public_deps allows the exposition of headers that live in another
target. This can lead to a really unhealthy build.
On the other side, all_dependent_configs is automatically propagated
up in the build graph but if a target includes a libyuv header it is
forced by GN to declare the dependency (and this will propagate
libyuv_config).

2. Two channels are processed at a time. R and B, and A and G.
3. vpshufb is used to shift and mask 2 channels of R and B
Red Blue
With the 8 bit value in the upper bits, vpmulhuw by (1024+4) will produce a 10
bit value in the low 10 bits of each 16 bit value. This is whats wanted for the
blue channel. The red needs to be shifted 4 left, so multiply by (1024+4)*16 for
red.
Alpha Green
Alpha and Green are already in the high bits so vpand can zero out the other
bits, keeping just 2 upper bits of alpha and 8 bit green. The same multiplier
could be used for Green - (1024+4) putting the 10 bit green in the lsb. Alpha
would be a simple multiplier to shift it into position. It wants a gap of 10
above the green. Green is 10 bits, so there are 6 bits in the low short. 4
more are needed, so a multiplier of 4 gets the 2 bits into the upper 16 bits,
and then a shift of 4 is a multiply of 16, so (4*16) = 64. Then shift the
result left 10 to position the A and G channels.
