I did check in the manual but did not find explanation for the following parameters for the json-output of the analyze plugin (I did check the Normalized output format paragraph)

pids.packet:

  • af
  • pcr-leap
  • dts-leap
  • pts leap
  • discontinuities: is this cc-errr?

thanks

  • af = number of packets with an adaptation field in the header, not necessarily meaningful, just an information.
  • pcr-leap, dts-leap, pts leap = "leap" in timestamps, meaning consecutive timestamps with suspect distance, typically more than a couple of seconds, probably a symptom of something going wrong. One exception: there is one expected leap every 26 hours when the integer value of the timestamps wraps down to zero.
  • discontinuities = errors in continuity counters, a symptom of missing or incorrect packets.
