What's New in the DirectShow 5.2b SDK?


The Microsoft® DirectX® Media 5.2b SDK is an update to the DirectX Media 5.1 SDK, released in November 1997. For a description of what was new in the DirectShow 5.1 SDK, see What's New in the DirectShow 5.1 SDK?

The DirectX Media 5.2b run time has improvements in two specific areas—DVD Playback and WDM Capture support.

For DVD playback, the run time provides support for PAL DVD discs as well as improved interactive responsiveness. The run time has also been tested with many new DVD titles that were released in the last two months.

The Overlay Mixer, which is a key rendering component for DVD playback, has been improved in the following areas.

The video and audio capture infrastructure has been enhanced to add support for more types of WDM streaming class capture hardware running under Microsoft® Windows® 98 or Windows NT® 5.0. If your application is going to work with this new hardware, you should re-read the capture interface descriptions and re-read the code for our sample capture application, Amcap.exe found in the Capture sample directory.

In addition, a new video control interface has been added, IAMVideoControl, that enables you to flip a picture horizontally and/or vertically, to set up a stream so that it can capture from an external trigger, to simulate an external trigger in software, and to list the current frame rate, maximum frame rate, and available frame rates.

A new filter, Smart Tee, has been added to aid preview on capture filters that only have a capture pin and not a preview pin.
