-----------
[Cocoa] AV1 codec strings specifying 4:2:0 Colocated subsampling incorrectly
fail
https://bugs.webkit.org/show_bug.cgi?id=278676
rdar://134375956
Reviewed by Eric Carlson.
Correct a mismatch between CoreMedia's definition of the ChromaSubsampling
parameter
and the definition used by the AV1 ISO-BMFF bindings specification. CoreMedia
uses
a definition whose low-order digit specifies monochrome support, and AV1 uses
chroma
sample position in that same digit.
Construct a query paratemer which matches CoreMedia's definition from the codecs
string provided. Also, do more validation of combinations of monochrome and
subsampling
coordinates.
