Howto 1: build a sample audio graph. | |
mediastreamer2 is a powerful engine to make audio and video streams. mediastreamer2 is GPL (COPYING). Please understand the licencing details before using it!

Mediastreamer2 can be used for a lot of different purpose. The primary use is to manage RTP audio and video session. You will need to use the API to build filters, link them together in a graph. Then the ticker API will help you to start and stop the graph.
Basic graph example:
The above graph is composed of three filters. The first one has no input: it captures audio data directly from the drivers and provide it to the OUTPUT pin. This data is sent to the INPUT pin of the encoder which of course encodes the data and sends it to its OUTPUT pin. This pin is connected to the INPUT pin of a filter capable of building and sending RTP packets.
The modular design helps you to encode in many different formats just by replacing the "ENCODE FILTER" with another one. mediastreamer2 contains internal support for g711u, g711a, speex and gsm. Other encoding formats can be added by implementing new filters as plugins which can then be dynamically loaded.
