RTPSessionMgr

- javax.media.rtp.RTPManager
- - net.sf.fmj.media.rtp.RTPSessionMgr

All Implemented Interfaces:

Controls, SessionManager
```
public class RTPSessionMgr
extends RTPManager
implements SessionManager
```
Kernel of the RTP stack. This is where almost everything is done. Instances of this class handle a single RTP session which is an association among a set of participants communicating with RTP. A participant may be involved in multiple RTP sessions at the same time. In a multimedia session, each medium is typically carried in a separate RTP session with its own RTCP packets (unless the the encoding itself multiplexes multiple media into a single data stream).

public RTPSessionMgr()
```
    Creates a new RTPManager
- Method Detail
  - formatSupported
```
public static boolean formatSupported(Format f)
```
    This is a function provided by Sun's implementation, which is not in the API as AFAIK - kenlars99. This does not include formats in the RTP bonus formats mgr. This is a somewhat dubious function, since the actual RTPSessionMgr used is determined by RTPManager.newInstance(). To the extend that Sun's code calls this function, it is assuming that its own RTPSessionMgr will be used, which may be the source of some problems.
    
    Parameters:
    f - the format which we want to test
    
    Returns:
    true if the format is supported Note: the format list in JMF is static, and in FMJ it is not. So you can add a format once with JMF, but you have to add it every time you instantiate the manager with FMJ.

```
public static Format[] getSupportedFormats()

  - RTPPacketSent
```
public void RTPPacketSent(long time,
                 int size)
```
    Sort of callback method called by RTPSendStreams to inform the RTPSessionManager they're linked to that an RTP packet has been sent by the local participant. This is used to maintain some local variables and statistics used in several algorithms (reaper timer and RTCP delay calculation for example).
    
    Parameters:
    time - time when the packet was sent
    size - size of the packet sent
  - getAverageRTCPSize
```
public int getAverageRTCPSize()
