WebM DirectShow Filters is the DirectShow filter package for WebM. DirectShow uses Filter Graph to manage Filters, where Filter Graph is the “container” of Filters and Filter is the smallest functional module of Filter Graph. WebM is a video format commonly used in web browsers such as Firefox and Chrome, as well as applications such as Skype, YouTube, and Wikimedia. In order to play any video file, you need the correct codec and filter. Therefore, if you do not have the appropriate codec/filter, you can not play the WEBM file.
