fecPacketsDiscarded/s

Average number of RTP FEC packets received per second for this SSRC where the error correction payload was discarded by the application.

Description

Real number

Average number of RTP FEC packets received per second for this SSRC where the error correction payload was discarded by the application.

This may happen:

  1. If all the source packets protected by the FEC packet were received or already recovered by a separate FEC packet
  2. If the FEC packet arrived late, i.e., outside the recovery window, and the lost RTP packets have already been skipped during playout

This is a subset of fecPacketsReceived/s.
