Video Profile
Select the video profile from list to configure.
H264
Resolution: There are four resolutions in this profile: SXGA(1280x1024), VGA(640x480),
QVGA(320x240) and QQVGA(160x128).
Rate Control: Defines the rate control method of this profile. There are two options: Constant
Bit Rate (CBR) or Variable Bit Rate (VBR). For CBR, the video bit rate would be fixed. User
can set the desired bit rate to match the limitation of bandwidth. For VBR, user could choose
the quality level. The quality level is between 1 and 100. The higher value can reach the better
quality but it will also need higher bandwidth.
Max Frame Rate: Defines the targeted frame rate of this profile. For example, set the frame
rate to 15 fps, then the image will be updated for 15 frames per second as possible. User need
to set reasonable frame rate with video quality under the limited bandwidth.
GOP Control: Defines the Intra/Inter-frame (I/P) ratio of this profile. For example, set the GOP
to 30, then the video stream will have one Intra-frame(I-frame) every 30 frames.
MPEG-4
Resolution: There are three resolutions in this profile: VGA(640x480), QVGA(320x240) and
QQVGA(160*128).

M-JPEG
