* Public Metadata API.
* The metadata API allows libavformat to export metadata tags to a client
- * application using a sequence of key/value pairs. Like all strings in FFmpeg,
+ * application using a sequence of key/value pairs. Like all strings in Libav,
* metadata must be stored as UTF-8 encoded Unicode. Note that metadata
* exported by demuxers isn't checked to be valid UTF-8 in most cases.
* Important concepts to keep in mind:
* filename -- original name of the file.
* genre -- <self-evident>.
* language -- main language in which the work is performed, preferably
- * in ISO 639-2 format.
+ * in ISO 639-2 format. Multiple languages can be specified by
+ * separating them with commas.
* performer -- artist who performed the work, if different from artist.
* E.g for "Also sprach Zarathustra", artist would be "Richard
* Strauss" and performer "London Philharmonic Orchestra".
