File Source (URL) Filter

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

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.
