        Detailed Description

        MediaHandler is the base media processing unit. Media handlers transform the input streams and propagate the outputs to downstream media handlers. There are three different types of media handlers: 1) Single input single output This is the most basic handler. It only supports one input and one output with both index as 0. 2) Multiple inputs multiple outputs The number of outputs must be equal to the number of inputs. The output stream at a specific index comes from the input stream at the same index. Different streams usually share a common resource, although they may be independent. One example of this is encryption handler. 3) Single input multiple outputs The input stream is split into multiple output streams. One example of this is trick play handler. Other types of media handlers are disallowed and not supported.
