File Source (URL) Filter
The URL File Source 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, MOV, MPEG, and WAV files. It requires the downstream filter to be a parser, such as the MPEG-1 Stream Splitter, the AVI Splitter, or the QuickTime Movie Parser.
