(ii) Profile: High profile provides better coding efficiency. Note that some devices
do not support every profile. For example, iPhone4 only supports Main profile.
(iii) Bitrate Control Mode: In CBR(Constant Bit Rate) mode, the bitrate keeps
consistent all over the video. In VBR(Variable Bit Rate) mode, the bitrate
changes with the complexity extent of the video data.
VBR provides a better compression way and the file may be smaller. However,
the VBR file size cannot be predicted. The image may become broken or lagged
when your bandwidth is not enough for the data quantity you selected.
(iv) Video Quantitative: The quality parameter of VBR. The higher the value is,
the higher the image quality is.
(v)
Video
Bitrate:
The quality parameter
of CBR.
You can choose
32kbps~10Mkbps. The higher the value is, the higher the image quality is.
(vi) Video Frame Rate: The video refreshing rate per second. The max value is
affected by the input resolution you choose.
(vii) GOP Size: It means “Group of Pictures”. The higher the GOP is, the better
the quality is.
(viii) Video Format: H.264 or M-JPEG.
(ix) RTSP Path: RTSP output connecting route.
d. 3GPP Streaming mode:
