Microsoft directshow 5 cakewalk1/29/2023 By comparison, the UncompAVItoWMV sample in this SDK works only with uncompressed AVI files. You can create DirectShow filter graphs that decode a wide variety of file and compression types, and then feed the decoded streams into the WM ASF Writer filter. DirectShow is especially useful when converting content from varied formats into Windows Media Format. You simply specify a profile using the IConfigAsfWriter interface on the filter, and DirectShow automatically loads the required components for rendering or writing the streams, and provides the mechanisms for transferring and synchronizing the flow of media data. With DirectShow streaming architecture, it takes only a few method calls to play Windows Media Audio or Windows Media Video files. There are two main reasons why an application might use DirectShow rather than the Windows Media Format SDK directly: for the convenience of the DirectShow streaming architecture, and for access to hardware.
