Bit 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 idea bit rate is between
256kbps and 4096kbps. User can set the desired bit rate to match the limitation of bandwidth.
For VBR, user should choose the quantization level to set the video quality rather than bit rate.
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. User can set the
desired max frame rate versus video quality under the limited bandwidth.
