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.
H.264 Profile Type
Select the H.264 profile type from "Baseline Profile" "Main Profile"
"High Profile" or "BP/MP/HP". The default setting is "Baseline Profile".
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.
Video Bit Rate
Configures bit rate for video call. The default setting is 2048 kbps. The
valid range is from 32 - 2048 kbps. 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.
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.
SDP Bandwidth Attribute
Select the SDP bandwidth attribute from "Standard" "Media Level"
"Session Level" and "No" to modify the session format. The default
setting is "Media Level".
 Standard: use AS format in session level; use TIAS format in
media level
 Media Level: use AS format in media level
 Session Level: use AS format in session level
 No: no modifications in the session format
Note:
Please do not modify this setting without knowing the session format
supported by the server. Otherwise, it might cause video decoding
failure.
H.264 Payload Type
Configures H.264 codec payload type. The default setting is 99. The
valid range is from 96 to 127.
SRTP Mode
Enable SRTP mode based on your selection from the drop-down
