+ * 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,
+ * 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:
+ * 1. Keys are unique; there can never be 2 tags with the same key. This is
+ * also meant semantically, i.e., a demuxer should not knowingly produce
+ * several keys that are literally different but semantically identical.
+ * E.g., key=Author5, key=Author6. In this example, all authors must be
+ * placed in the same tag.
+ * 2. Metadata is flat, not hierarchical; there are no subtags. If you
+ * want to store, e.g., the email address of the child of producer Alice
+ * and actor Bob, that could have key=alice_and_bobs_childs_email_address.
+ * 3. Several modifiers can be applied to the tag name. This is done by
+ * appending a dash character ('-') and the modifier name in the order
+ * they appear in the list below -- e.g. foo-eng-sort, not foo-sort-eng.
+ * a) language -- a tag whose value is localized for a particular language
+ * is appended with the ISO 639-2/B 3-letter language code.
+ * For example: Author-ger=Michael, Author-eng=Mike
+ * The original/default language is in the unqualified "Author" tag.
+ * A demuxer should set a default if it sets any translated tag.
+ * b) sorting -- a modified version of a tag that should be used for
+ * sorting will have '-sort' appended. E.g. artist="The Beatles",
+ * artist-sort="Beatles, The".
+ *
+ * 4. Tag names are normally exported exactly as stored in the container to
+ * allow lossless remuxing to the same format. For container-independent
+ * handling of metadata, av_metadata_conv() can convert it to ffmpeg generic
+ * format. Follows a list of generic tag names:
+ *
+ * album -- name of the set this work belongs to
+ * album_artist -- main creator of the set/album, if different from artist.
+ * e.g. "Various Artists" for compilation albums.
+ * artist -- main creator of the work
+ * comment -- any additional description of the file.
+ * composer -- who composed the work, if different from artist.
+ * copyright -- name of copyright holder.
+ * date -- date when the work was created, preferably in ISO 8601.
+ * disc -- number of a subset, e.g. disc in a multi-disc collection.
+ * encoder -- name/settings of the software/hardware that produced the file.
+ * encoded_by -- person/group who created the file.
+ * filename -- original name of the file.
+ * genre -- <self-evident>.
+ * language -- main language in which the work is performed, preferably
+ * in ISO 639-2 format.
+ * 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".
+ * publisher -- name of the label/publisher.
+ * title -- name of the work.
+ * track -- number of this work in the set, can be in form current/total.

+ * Pixel format. Notes:
+ *
+ * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
+ * color is put together as:
+ * (A << 24) | (R << 16) | (G << 8) | B
+ * This is stored as BGRA on little-endian CPU architectures and ARGB on
+ * big-endian CPUs.
+ *
+ * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
+ * image data is stored in AVFrame.data[0]. The palette is transported in
+ * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
+ * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
+ * also endian-specific). Note also that the individual RGB palette
+ * components stored in AVFrame.data[1] should be in the range 0..255.
+ * This is important as many custom PAL8 video codecs that were designed
+ * to run on the IBM VGA graphics adapter use 6-bit palette components.
+ *
+ * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
+ * for pal8. This palette is filled in automatically by the function
+ * allocating the picture.
+ *
+ * Note, make sure that all newly added big endian formats have pix_fmt&1==1
+ * and that all newly added little endian formats have pix_fmt&1==0
+ * this allows simpler detection of big vs little endian.

-/*
- * 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,
- * 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:
- * 1. Keys are unique; there can never be 2 tags with the same key. This is
- * also meant semantically, i.e., a demuxer should not knowingly produce
- * several keys that are literally different but semantically identical.
- * E.g., key=Author5, key=Author6. In this example, all authors must be
- * placed in the same tag.
- * 2. Metadata is flat, not hierarchical; there are no subtags. If you
- * want to store, e.g., the email address of the child of producer Alice
- * and actor Bob, that could have key=alice_and_bobs_childs_email_address.
- * 3. Several modifiers can be applied to the tag name. This is done by
- * appending a dash character ('-') and the modifier name in the order
- * they appear in the list below -- e.g. foo-eng-sort, not foo-sort-eng.
- * a) language -- a tag whose value is localized for a particular language
- * is appended with the ISO 639-2/B 3-letter language code.
- * For example: Author-ger=Michael, Author-eng=Mike
- * The original/default language is in the unqualified "Author" tag.
- * A demuxer should set a default if it sets any translated tag.
- * b) sorting -- a modified version of a tag that should be used for
- * sorting will have '-sort' appended. E.g. artist="The Beatles",
- * artist-sort="Beatles, The".
- *
- * 4. Tag names are normally exported exactly as stored in the container to
- * allow lossless remuxing to the same format. For container-independent
- * handling of metadata, av_metadata_conv() can convert it to ffmpeg generic
- * format. Follows a list of generic tag names:
- *
- * album -- name of the set this work belongs to
- * album_artist -- main creator of the set/album, if different from artist.
- * e.g. "Various Artists" for compilation albums.
- * artist -- main creator of the work
- * comment -- any additional description of the file.
- * composer -- who composed the work, if different from artist.
- * copyright -- name of copyright holder.
- * date -- date when the work was created, preferably in ISO 8601.
- * disc -- number of a subset, e.g. disc in a multi-disc collection.
- * encoder -- name/settings of the software/hardware that produced the file.
- * encoded_by -- person/group who created the file.
- * filename -- original name of the file.
- * genre -- <self-evident>.
- * language -- main language in which the work is performed, preferably
- * in ISO 639-2 format.
- * 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".
- * publisher -- name of the label/publisher.
- * title -- name of the work.
- * track -- number of this work in the set, can be in form current/total.

- * Pixel format. Notes:
- *
- * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
- * color is put together as:
- * (A << 24) | (R << 16) | (G << 8) | B
- * This is stored as BGRA on little-endian CPU architectures and ARGB on
- * big-endian CPUs.
- *
- * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
- * image data is stored in AVFrame.data[0]. The palette is transported in
- * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
- * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
- * also endian-specific). Note also that the individual RGB palette
- * components stored in AVFrame.data[1] should be in the range 0..255.
- * This is important as many custom PAL8 video codecs that were designed
- * to run on the IBM VGA graphics adapter use 6-bit palette components.
- *
- * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
- * for pal8. This palette is filled in automatically by the function
- * allocating the picture.
- *
- * Note, make sure that all newly added big endian formats have pix_fmt&1==1
- * and that all newly added little endian formats have pix_fmt&1==0
- * this allows simpler detection of big vs little endian.
