bool tagParseExtendedComment(string extComment,  out  string key,  out  string lang,  out  string value,  bool  failIfNoKey)

Convenience function to parse a GST_TAG_EXTENDED_COMMENT string and separate it into its components.

If successful, key, lang and/or value will be set to newly allocated strings that you need to free with [glib.global.gfree] when done. key and lang may also be set to NULL by this function if there is no key or no language code in the extended comment string.

`key`	return location for the comment description key, or NULL
`lang`	return location for the comment ISO-639 language code, or NULL
`value`	return location for the actual comment string, or NULL
`failIfNoKey`	whether to fail if strings are not in key=value form

Returns

TRUE if the string could be parsed, otherwise FALSE
