Configuring Script Streams

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Like all arbitrary stream types, script streams need to have a bit rate and buffer window defined for them. The major media type in the WM_MEDIA_TYPE structure must be set to WMMEDIATYPE_Script.

Script streams need to have the formattype member of WM_MEDIA_TYPE set to WMFORMAT_Script, which indicates that the pbFormat member points to a WMSCRIPTFORMAT structure.

There is only one supported script type, WMSCRIPTTYPE_TwoStrings.
