DESCRIPTION
For nvideoin >= 2, the definition is
different:
First all 32 bits are divided into groups
for channel.
Ex:
nvideoin = 2, bit 0~15 are the 1st
group for 1st channel, bit 16~31 are
the 2nd group for 2nd channel.
nvideoin = 3, bit 0~9 are the 1st group
for 1st channel, bit 10~19 are the 2nd
group for 2nd channel, bit 20~31 are
the 3rd group for 3rd channel.
Then, the 1st bit of the group
indicates 1st stream of a channel
support ePTZ or not. The 2nd bit of
the group indicates 2nd stream of a
channel support ePTZ or not, and so
on.
* For most products, the last stream
of a channel will not support ePTZ. It
is reserved for full view of the
channel. For some dual-stream
products, both streams support ePTZ.
