3.6 How to Stream H.264
Deciding on the combination of protocols and methods to use depends on user viewing requirements a local
network properties. Setting the preferred method(s) is done on the Setup page.
o
RTP+RTSP:
This method (actually RTP over UDP and RTSP over TCP) should be the first consideration for live
video, especially when it is important to always have an up-to-date video stream, even if some of the images
are lost due to network problems. This can be configured as unicast or multicast.
o
RTP/RTSP/Multicasting:
This provides the most efficient use of bandwidth, especially when there are large
numbers of clients connecting simultaneously. Note, however, that a multicast broadcast cannot pass a
network router unless the router is configured to allow this. For example, it is impossible to multicast over
the Internet.
o
RTP/RTSP/Unicasting:
This should be used for video-on-demand broadcasting so that there is no video traffic
on the network until a client connects and requests the stream. However, as more and more unicasts clients
connect, the traffic on the network will increase and may cause congestion. Although there is a maximum of
8 unicast viewers, note that all multicast viewers combined count as 1 unicast viewer.
o
RTP/RTSP:
This unicast method is RTP tunneled over RTSP. This could be used to exploit the fact that it is
relatively simple to configure firewalls to allow RTSP traffic.
