Hi,
I just noticed that ... now vlc will take "a bit longer" to finish 
quitting it seems to be waiting for more data to come.
Time is increased between "main decoder debug: removing module 
"avcodec"" and "main input debug: releasing aout".
For a HD clip it took approximately 1.5 seconds (or more) to finish 
quitting vlc.exe process with a lot more decoder warnings.

The binary is with --disable-optimize-memory support.

This problem affects "avcodec" decoder.

Shutting down got delayed. Is it possible that video decoders get killed 
at first priority?

So that it won't have to wait for more data?
