    mimeType: String!,
    codecPrefix: String!,
    @C.TrackType trackType: Int
): Unit

Registers a custom MIME type. Most applications do not need to call this method, as handling of standard MIME types is built in. These built-in MIME types take precedence over any registered via this method. If this method is used, it must be called before creating any player(s).

Parameters
`mimeType: String!`	The custom MIME type to register.
`codecPrefix: String!`	The RFC 6381 codec string prefix associated with the MIME type.
`@C.TrackType trackType: Int`	The `track type` associated with the MIME type. This value is ignored if the top-level type of `mimeType` is audio, video or text.
