Kernel streaming test method and system
A method and system for testing software filters used in a multimedia environment to support kernel streaming. In a computer, a source module generates a data stream in order to emulate a multimedia input device, such as a microphone or video camera. A plurality of software filters are communicatively coupled to form a software filter chain. The chain of software filters receives the data stream from the source module and propagates the data stream through each software filter for processing. An analysis module receives the processed data stream from the chain of software, filters and produces performance information as a function of the received data stream. The source module, the analysis module and each software filter operate in a kernel-mode and are configured by a test tool operating in non-kernel mode. Via the test tool, a user can select appropriate source and analysis modules as well as construct the chain of software filters to include a large number of software filters. In order to assess the functionality of a large number software filters under real-world conditions using a single computer, the invention couples the software filters by one or more virtual circuits that route the data stream to and from a network.
