Description
This value, as compared to the configured Jitter Queue Time and in
combination with the Jitter Queue Minimum Depth, gives you an
indication of the amount of jitter in the current connection and
how well the decoder is handling that jitter. If this value is negative,
the jitter queue is under flowing and the decoder probably will not
be able to keep audio and video in sync. For more information see
Latency and Quality Tuning.
An increasing count here is an indication that the configured Jitter
Queue Time may be too small given the network conditions and
encoder configuration. The 9000 Series decoder is designed to
minimize the effects of video and audio frame drops, so for
aggressive low latency applications, you may decide to set the Jitter
Queue Time so low as to cause some frames to be dropped but
keeping your video/audio quality still acceptable. For more
information see Latency and Quality Tuning.
Partial frame persistent for > 5 seconds. Indicates a network issue.
An increasing count indicates that the decoder is unable to process
the received stream. Check for system overload conditions.
Count of RTP fragments with a duplicate sequence counter (per
frame). Indicates an encoder and/or network issue.
Count of RTP packets that failed validation. Indicates an encoder
and/or network issue.

In the H.264/AVC standard, a specified "Level" indicates certain
quantitative capabilities of bit stream decoding. For example, the
level-constrained decoding capabilities specify the maximum
resolution, maximum frame rate and maximum bit rate of video the
decoder is able to decode. A decoder conforming to a given level
must be able to decode bit streams at that level and all lower levels.
