The file source (URL) filter is a generic asynchronous source filter that works with any source file that can be identified by a Uniform Resource Locator (URL) and whose media major type is stream. This includes AVI, MPEG, and WAV files. It requires the downstream filter to be a parser, such as the MPEG-1 stream splitter, or the AVI splitter.
