FFDSHOW will then connect it's input pins to Haali's output pins and decode the video stream. For example, the Input pin of the Haali Media Splitter will receive the data from the file, split it to it's component parts and then output those "streams" via it's output pins. Pins are the means by which media data is passed from one filter to another filter. Filters have âpinsâ - points of connection between filters, both input pins and output pins. Each filter in the Filter Graph chain processes audio/video data in a specific way to facilitate the playing of the media files. They are sort of like little "plugins" for DirectShow that allow it to handle different types of media, different types of files, or perform transformations on the media data. A filter is a software component in DirectShow that will work with other similar components to render a media file. A filter graph is like a chain of individual âDirectShow Filtersâ. DirectShow is a Microsoft technology for playing (and recording) audio/video media on a Windows computer.ĭirectShow uses the concept of âFilter Graphâ to take a multimedia file on disk and turn it into what you see or hear from your computer.
