For VBR, user should choose the quality level to set the video quality rather
than bit rate. The quality level is between 1 and 100. The higher value can
reach the better quality but of course will consume higher bandwidth.
For ECBR, the video bitrate is based on normal CBR mode. However, the
target bitrate can be increased to max target bitrate while lots of motion in
video. The max target bitrate will keep a pre-defined time period and then back
to normal CBR bitrate.
For EVBR, the video bitrate is based on normal VBR mode. However, the
target bitrate can be increased to max target bitrate while lots of motion in
video. The max target bitrate will keep a pre-defined time period and then back
to normal VBR mode.
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 max frame rate versus 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 every 30 frames.
