For "nvideoin" = 1, the definition is as
following:
A 32-bits integer, each bit can be set
separately as follows:
Bit 0 => 1st stream supports ePTZ or not.
Bit 1 => 2nd stream supports ePTZ or not, and
so on.
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
