Can be introduced under a rough idea of what?
(1) X264 a YUV420 convert H264;
(2) According to the RTMP protocol, set the parameters LibRTMP control interface functions,
mainly to set the message header, message body, set the message type, packet length, data type video parameters ;
(3) NAL copied to a LibRtmp structure,
then with RTMP_SendPacket (r, & packet, 0);
contract to Wowza, Red5 can?

//Thread
While (ThreadIsRunning && RTMP_IsConnected(r) && RTMP_ReadPacket(r, &packet))
{
if (RTMPPacket_IsReady(&packet))
{
if (!packet.m_nBodySize)
continue;
RTMP_ClientPacket(r, &packet); //This takes care of handling ping/other messages
RTMPPacket_Free(&packet);
}
}
