MultiFile Source Filter

The Microsoft® DirectShow® MultiFile source filter provides for playback of multiple files and file segments with identical media formats as a single stream, with relatively instantaneous file transitions. The filter performs this task for files containing an MPEG-2 program stream.

The MultiFile source filter supports the following interfaces in addition to the usual filter interfaces. For a list of the filter interfaces, see Filter-Level Interfaces.

IFileSourceFilter—you can use this to specify an initial file from which the type of the file(s) can be determined.
IMultiFileReader—sets file segments to play.
