The Be Book - System Overview - The Media Kit
The BMediaFormats
class provides a means for translating between BeOS
media format identifiers and those used by the codecs themselves. This is
primarily useful if you're writing a codec add-on or a file format parser.
The BMediaFormats
class currently knows how to translate among the
following formats' codec identification methods:
BeOS uses a constant within the media_format structure to indicate the kind of media being handled.
QuickTime uses a two-word vendor/codec pair to indicate the type of media.
The media format is indicated by a one-word constant.
The media format is indicated by a one-word constant.
The media format is indicated by a 128-bit UUID value.
The media format is specified by a word that indicates the MPEG version and layer.
The media format is specified by a codec ID word.
The media format is specified by a codec ID word.
The media format is indicated by a one-word file format value and a one-word codec ID.
