Description
Source IP address and port number of the stream.
Number of frames received.
Aggregate sum of frames dropped by Jittter, Age, and Rx Buffer
Overflow. Note that the 9000 Series decoder is designed to
minimize the negative effects of video and audio frame drops so
your video/audio quality may still be acceptable even if challenging
networks or aggressive low latency configurations cause frame
drops.
Number of bytes received.
Calculated bit rate.
Represents the number of times the jitter queue went empty. The
decoder may or may not be dropping frames, but this count
represents at least a warning condition that the configured Jitter
Queue Time is too small for the network conditions and/or the
encoder configuration. You can use this count to help achieve a
trade-off between low latency and dropped frames by reducing the
configured Jitter Queue Time until you see this count incrementing
slowly, with only a few or no Frames Dropped By Jitter. For more
information see Latency and Quality Tuning.
These counts indicate that large bursts of data are reaching the
decoder and filling the jitter queue. The queue can hold nearly 2
seconds of data so this would indicate either a severe network issue
or a problem with the encoder or decoder.
The lowest level the jitter queue has reached. A negative value
indicates the jitter queue went past empty by that amount. You can
use this statistic to tune your configured Jitter Queue Time to
obtain the lowest decoder latency without under flowing the jitter
queue too much or too often. For more information see Latency
and Quality Tuning.
