Format Type, Media Type, and Media Subtype Constants

The constants listed below indicate the format types, media types, and media subtypes supported by this toolkit. For further information on the supported formats, media types, and media sub-types, refer to Microsoft's Windows Media Format SDK documentation.

In addition to the codecs required to compress and decompress audio and video data, LEADTOOLS provides several multiplexers and demultiplexers for various container formats, such as ISO (MP4), OGG, WebM (MKV), and FLV. For a complete list and additional information, refer to the LEADTOOLS Filters, Codecs, and Interfaces documentation.
