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 | BeOS uses a constant within the media_format structure to indicate the kind of media being handled. |
QuickTime | QuickTime uses a two-word vendor/codec pair to indicate the type of media. |
AVI | The media format is indicated by a one-word constant. |
AVR | The media format is indicated by a one-word constant. |
ASF | The media format is indicated by a 128-bit UUID value. |
MPEG | The media format is specified by a word that indicates the MPEG version and layer. |
AIFF | The media format is specified by a codec ID word. |
WAV | The media format is specified by a codec ID word. |
Miscellaneous | The media format is indicated by a one-word file format value and a one-word codec ID. |
