Encoded Media Catalog Items and Sysgen Variables (Windows Embedded Compact 7)
In Windows Embedded Compact 7, you can add support for specific audio or video formats by adding the associated codecs, file support, filters, or renderers. The audio/video formats that are supported by Compact 7 are listed in the table below together with the SYSGEN variables that add them to the OS.
For more information, see Audio, Graphics and Media.
For more information about how to add or remove catalog items, see Design Your First OS.
The following table shows the catalog items and associated SYSGEN variables that you can use to add support for specific media formats to your OS. If you include a media player in your OS design, these SYSGEN variables determine the media formats that it will be able to play.
