[MPlayer-dev-eng] [PATCH] Unlock mutex before destroying it

[Jan Knutar]

Hi,
I retrieved this patch from NetBSD pkgsrc,
http://ftp2.skynet.be/pub/ftp.netbsd.org/packages/pkgsrc/multimedia/mplayer-share/patches/patch-ab

The cvs log entry had the following:

Unlocking a mutex before destroying it makes libpthread much happier.

pthread_mutex_destroy(3) seems to agree, but also seems to hint that
the call is essentially NOOP on Linux, which doesn't necessarily apply
to other OSen...

Tested on Linux with a few files requiring win32 codec, no side effects
apparent.
