channel 2 stream 2, and
so on.
For stream 3 of all
channels:
239.128.1.(99+n*2) for
channel 1 stream 3.
239.128.1.(100+n*2) for
channel 2 stream 3, and
so on.
videoport 1025 ~ 65535 For stream 1 of all
channels:
5560+(c-1)*4
For stream 2 of all
channels:
5560+n*4*(s-1)+(c-1)*4
And so on.
4/4 Multicast video port.
audioport 1025 ~ 65535 For stream 1 of all
channels:
5562+(c-1)*4
For stream 2 of all
channels:
5562+n*4+(c-1)*4
And so on.
4/4 Multicast audio port.
(capability.naudio > 0)
ttl 1 ~ 255 15 4/4 Mutlicast time to live value.
For compatibility, network_rtsp_s<0~(t-1)>_multicast are reserved, t = n*m for n channel products,
and m is stream number per channel.
*Note: We can get n by (capability.nvideoin), and get m by (capability.nmediastream).
Besides, we map the first stream of each channel: network_rtsp_c<0~(n-1)>_s0_multicast to
network_rtsp_s<0~(n-1)>_multicast and map the second stream of each channel:
network_rtsp_c<0~(n-1)>_s1_multicast to network_rtsp_s<n~(n*2-1)>_multicast and so on.
Take VS8401 as an example, channel 1 stream 1 is mapped to network_rtsp_s0_multicast and
channel 1 stream 2 is mapped to network_rtsp_s4_multicast.
