This patchset allows ring application to tune 2 parameters of
libav jitter buffer:
- buffer size: maximal amount of packets to be queued
- packet delay: maximal amount of time a packet can be queued

Tuning those values allows correct handling of packet reordering issues
and network jitter.
Notice that for the moment default libav values are set.

Issue: #80311
