The default setting is 720P.
Note: For some network environment, the default setting "720P" might
be too high that causes no video or video quality issue during video
call. In this case, please change "H.264 Image Size" to "VGA" or "CIF"
and change "Video Bit Rate" to "384kbps" or lower.
It is used to set the H.264 profile type. It can be selected from the
dropdown list.

Baseline Profile

Main Profile

High Profile

BP/MP/HP
The default setting is "Baseline Profile".
Note: Lower levels are easier to decode, but higher levels offer better
compression. Usually, for the best compression quality, choose "High
Profile"; for playback on low-CPU machines or mobile devices, choose
"Baseline Profile". If "BP/MP/HP" is selected, all three profiles
"Baseline Profile" "Main Profile" and "High Profile" will be used for
negotiation during video decoding to achieve the best result. This is
usually used in video conference when there is higher requirement on
the video.
It is used to configure the bit rate for video call. It can be selected from
the dropdown list. The default setting is 2048 kbps. The valid range is
from 32 - 2048 kbps.
Note: The video bit rate can be adjusted based on the network
environment. Increasing the video bit rate may improve video quality if
the bandwidth is permitted. If the bandwidth is not permitted, the video
quality will decrease due to packet loss. For some network
environment, the default setting "720P" might be too high that causes
no video or video quality issue during video call. In this case, please
change "H.264 Image Size" to "VGA" or "CIF" and change "Video Bit
Rate" to "384kbps" or lower.
It is used to set the SDP bandwidth attribute. It can be selected from
the drop down list.
