An explicit application-provided decision to allow or deny a codec,
bypassing the browser's support detection.
'allow' forces the codec to be treated as supported even if the browser
reports it unsupported (e.g. to opt in to a codec the app knows the
platform can decode via an external path).
'deny' forces the codec to be treated as unsupported even if the browser
reports it supported (e.g. to work around a browser that falsely claims
support, or to exclude a codec by policy).
