The RTSP audio source filter uses the open source LGPL'd live media streaming library available at http://www.live555.com.
This filter serves as an example of how a RTSP/RTP library can be used to create a DirectShow source filter since no standard-conformant RTSP source filter is currently available in the DS framework.
It currently only supports the following formats: 8 and 16bit PCM, AMR and MP3.
Other formats might be added at a later stage as required.
The AMR support requires the use of the DirectShow AMR filters available at .
The filter pack is available under the GPL.
