For compatibility,

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
.
