specification.<p>This library is used by a number of Bluetooth profiles and implements Audio/Visual Distribution Transport Protocol Specification. The Audio/Video Distribution Transport Protocol Specification (hereafter referred to as AVDTP) is used to transport Audio/Video streams over an L2CAP connection.<p>Commands and responses for executing the stream setup procedure are defined as Bluetooth specific. AVDTP defines the binary transactions between Bluetooth devices for stream setup and media streaming for audio and video using L2CAP.<p>A/V streaming and stream setup signalling are transported via L2CAP packets. A dedicated Protocol/Service Multiplexer (PSM) value is used to identify L2CAP packets that are intended for AVDTP.<p>The library exposes a functional downstream API and an upstream message based API.<hr><h2>Define Documentation</h2><a class="anchor" name="a0" doxytag="gavdp.h::AVDTP_SERVICE_MEDIA_TRANSPORT" ></a><p><table class="mdTable" width="100%" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> #define AVDTP_SERVICE_MEDIA_TRANSPORT (1) </td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>The capability to stream media.
