 This video plays fine at first, but about 130 seconds in it starts
 spamming these messages:
 {{{

 This is with latest git (fa125c5e82fce4). A user reported that a 2 week
 old Libav actually caused failed with an assertion on this.

 No, I won't follow the cehoyos ritual, don't even ask. It's easily
 reproducible.
