Avaya Aura 5300 User Manual page 89

If your video camera does not support a video capture format that is usable by the H.264
CODEC, then the H.264 CODEC does not appear as a choice.
3. Select one of the Codec Quality Settings or click Config.
Use custom video configurations with care. The combination of a large video image size,
high quality CODEC setting, and high Frames Per Second (FPS) produces video
transmission rates over 1 Mbit/s and erodes network and PC performance. Avaya
recommends that you use one of the pre-defined video configurations.
4. Use the guidelines in the table to adjust the custom video configuration.

5. Click OK.
Both clients in a call must support H.264 video CODEC in order to send and receive.
However, if either client does not have H.264 then H.263 video is sent.
The following table lists the H.264 Codec Quality Settings default values.

About this task
Not all CODECs are supported in all installations. Contact your system administrator to determine
what CODECs are available for you to use, or check your Personal Agent.

Description
This specifies the maximum bitrate that the encoder transmits, not
including header information. Drag the slider or enter a value in the
text box.
This value allows you to change the interval of sending keyframes,
which could reduce the bandwidth requirement at the cost of quality.
The default value is 8 (medium, high, and very high quality settings),
and you can specify values between 1 and 300.
This value allows you to improve the frame rate of the video at the
cost of quality. A lower value for Video Fluidity produces more
choppy video motion, with a higher image quality for each frame of
video. The default value is 100 (all quality settings).
This setting improves higher quality encoding of video, at the cost of
more CPU. Almost twice the CPU usage is required, when this
setting is enabled, for a picture quality improvement of almost 1db in
SNR, at the same bitrate.
