Ping.  [insert summary message here.]

[insert witty comment to get attention of ffmpeg developers].

[insert follow up witty comment to get slight chuckle]

[insert final follow up comment that i think is funny, but ultimately

ffmpeg developers, leading to death match like Ivan vs. Diego except
actually Art vs. Rhino to see who can best take a headbutt to stomach]

[insert final plea for patch to be cleanly reviewed or rejected]
