max_size: Defaults to 200 ms

The length in milliseconds over which a timestamp difference will result in resyncing the jitterbuffer.

target_extra: Defaults to 40ms

This option only affects the adaptive jitterbuffer. It represents the amount time in milliseconds by which the new jitter buffer will pad its size.
