The User Agent MAY use this hint to set
expectations about incoming {{VideoFrame}}s and to improve encoding quality.
+ If using this hint:
+ - The User Agent MUST respect other explicitly
+ set encoding options when configuring the encoder, whether they are
+ codec-specific encoding options or not.
+ - The User Agent SHOULD make a best-effort
+ attempt to use additional configuration options to improve encoding
+ quality, according to the goals defined by the corresponding
+ [=video content hint=].
+
+ NOTE: Some encoder options are implementation specific, and mappings between
+ {{VideoEncoderConfig/contentHint}} and those options cannot be
+ prescribed.
The User Agent MUST NOT refuse the configuration
if it doesn't support this content hint.
See {{VideoEncoder/isConfigSupported()}}.
