Class AACStream

java.lang.Object

net.majorkernelpanic.streaming.MediaStream

net.majorkernelpanic.streaming.audio.AudioStream

net.majorkernelpanic.streaming.audio.AACStream

All Implemented Interfaces:

Stream

public class AACStream
extends AudioStream

A class for streaming AAC from the camera of an android device using RTP. You should use a Session instantiated with SessionBuilder instead of using this class directly. Call MediaStream.setDestinationAddress(InetAddress), MediaStream.setDestinationPorts(int) and AudioStream.setAudioQuality(AudioQuality) to configure the stream. You can then call start() to start the RTP stream. Call stop() to stop the stream.
