1) Video format
Support 50HZ(PAL)and 60HZ(NTSC),and Dial priority three formats.
2) Video Coding
Support baseline and mainprofile format
3) Resolution
Main bit flow support 1920x1080,1280x720,minor bit flow support 640x360,320x180,the bigger
resolution is, the clearer the image will be, more network bandwidth will be taken.
4) Bit Rate
User can assign bit flow/stream, normally speaking, the bigger bit flow is, the clearer the image will be.
The bit allocation must combine with network bandwidth, when the network bandwidth is too narrow
and the allocated bit flow is too big, will cause video signal flow not to be transmitted normally, the
video effect will be worse.
5) Maximum frame rate:
User can specify the size of the frame rate, generally, the frame rate greater, the image more smooth;
Frame rate is smaller, the more sense of beating.
6) Bit Rate:
Code stream control way:
Constant bit rate: video coder will be coding according to preset speed
Variable bit rate: video coder will adjust the speed based on preset speed to gain the best image quality.
7) I key frame interval:
Set interval between 2 I frame, the bigger interval is, the response will be lower from viewing window.
8) Fluctuate level
Restrain the fluctuation magnitude of variable rate, grade 1 ~ 6
