| 40 | * other PJMEDIA transports, the loop transport may be attached to multiple |
| 41 | * streams (in other words, application should specify the same loop transport |
| 42 | * instance when calling #pjmedia_stream_create()). Any RTP or RTCP packets |
| 43 | * sent by one stream to this transport by default will be sent back to all |
| 44 | * streams that are attached to this transport, including to the stream that |
| 45 | * sends the packet. Application may individually select which stream to |
| 46 | * receive packets by calling #pjmedia_transport_loop_disable_rx(). |
