Detailed Description
Passive Media Patch In contrast to the 'default' media patch does this instance not run it's own thread. Instead, the source stream may push data to the sinks whenever needed. Useful for implementations where the source is not a continuous data stream (e.g. H.224/H.281 FECC, where data is sent on user input) or the source stream is driven by an external thread loop.
