Jumpy Video
Problem
The video display appears to be unstable.
Possible Cause
When the Cisco Unified MeetingPlace
is set to standard rate, and
and video terminals are using the H.264 codec, Cisco Unified MeetingPlace negotiates the video
connection at 15 frames per second, which is consistent with the H.264 Level 1.2 specification.
However, many video terminals ignore the frame rate limitation for H.264 Level 1.2 and send frames
at a higher rate. This overloads the Cisco Unified MeetingPlace video blade and results in corrupted
video output. Note that the effect may be observed on terminals other than the one causing the
problem.
