// The VP9 codec string is defined by the "Codecs Parameter String" section of
// the VP Codec ISO Media File Format Binding, which constrains bit depth and
// chroma subsampling by profile: profile 0 is 8-bit 4:2:0, profile 1 is 8-bit
// 4:2:2/4:4:4, profile 2 is 10/12-bit 4:2:0 and profile 3 is 10/12-bit
// 4:2:2/4:4:4. A codec string that does not meet these constraints is not a
// valid codec string, so Check Configuration Support returns false.
