31 * Class representing outgoing RTP stream in MCE. |

32 * |
|
33 * CMceRtpSink can be used to send media data to network. |
|
34 * It can be configured not to use RTCP during play in order |
|
35 * to save bandwith. |
|
36 * |
|
37 * CMceRtpSink allows also explicitly sending of RTP RR and SR |
|
38 * messages. |
|
39 * |
|
40 * Enable and Disable operations to it are considered |
|
41 * to be local, so they are not signalled to remote terminal. |
