Limitations and known issues
This section includes known issues or limitations that affect functionality or usability and ways that you can
work around these limitations.
Affecting encoding
l
Encoding with MPEG-4 sometimes results in poor quality.
Workaround: From the channel's stream setup, increase the video bitrate to improve picture quality.
l
Video bitrate for MJPEG streams are approximately one and a half to two times the configured value.
Workaround: Verify the actual bitrate on the channel's channel status page and adjust until the correct
value is achieved.
l
In multiple source channel layouts, sources cannot overrun the top or left edges of the screen.
Workaround: Avoid using negative values for x and y axis coordinates.
l
Encoding is unavailable if a branding logo is placed outside the frame size. (i.e. if the frame is 1024x768
and the logo is placed with an x-axis margin of 1200.)
Workaround: Always keep the branding logo within the frame.
l
For VGA sources only, some wide-mode resolutions are not correctly identified and result in a slightly
squished image (e.g. for a 1360x768 source, the detected resolution may be 1024x768).
Workaround: This issue is related to the video output hardware. Test your source to see if it exhibits the
