Bugzilla Bug 203430

mplayer 1.0_rc2_p24929 sometimes crashes in mysterious ways, and sometimes just
hangs, when using the "pulse" output driver.

Apparently mplayer is calling the libpulse API without holding a necessary
lock.  Here is what the pulse guys have to say about this:
http://www.pulseaudio.org/ticket/166

It looks like the mplayer guys checked in a similar patch for this on
2007-12-15, svn r25414.  Perhaps a simple package update will fix this.

It doesn't happen very often and is unpredictable, but it happens a few times a
day during heavy use.  Since it is locking-related, an SMP machine might be
required to reproduce this... running on a dual core processor here.  Both I
and the reporter of the pulse trac ticket (above) are running on amd64, but I
don't believe this is an amd64-specific issue.

Reproducible: difficult, random
Step 1: find a 2 hour avi file or dvd or something, fire up mplayer -ao pulse
Step 2: wait and hope it crashes (crashes about once per 4-6 hours of use,
here)

mplayer-pulse.patch

use pulseaudio && epatch "${FILESDIR}/${PN}-pulse.patch"

This patch makes mplayer work reliably for me.  It is the patch attached to the
pulseaudio ticket, reissued to remove some line numbering fuzz.

Fixed in CVS, thanks Mark
