Subject: [PATCH] ad_lavc: increase number of packets for initial decode

Apparently just 5 packets is not enough for the initial audio decode
(which is needed to find the format). The old code (before the recent
refactor) appeared to use 5 packets, but there were apparently other
code paths which in the end amounted to more than 5 packets being read.

The sample that failed (see github issue #368) needed 9 packets.

Fixes #368.
