Full Text Bug Listing

In kmplayer, when using  the "mplayer" engine, nothing will play.  The sound 
file will load, but not play, and then the status bar displays "Mplayer not
running"  as if the sound clip had finished.

A little hacking and web searching revealed that:

As of mplayer-1.0_rc2, the deprecated -vop option to mplayer has been removed
(it has been replaced by the -vf option).  This breaks applications, such as
kmplayer, that have the -vop flag hard-coded into the source.

I will attach a patch and a new ebuild below.  I've tested it on an AMD64
machine, but no longer have an x86 box to test stuff on.

Reproducible: Always

Steps to Reproduce:
1.  Install the latest version of mplayer from the portage tree.
2.  Install kmplayer.
3.  Launch kmplayer and open a sound file.
4.  Click "play"

Actual Results:  
Nothing plays, status bar gives "Mplayer not running".

Expected Results:  
Played the sound file.

Patch to replace 'vop' flag with 'vf' flag in kmplayer source.

This worked for me and ought to work on other platforms.  Could have done the
same thing with sed in the ebuild, I guess (since that's how I patched it).  If
that's preferable to a patch file here are the commands I used:

sed -i -e 's/vop/vf/g' ${S}/src/*.cpp
sed -i -e 's/vop/vf/g' ${S}/src/*.h

My emerge info

Oops.  Forgot to put my emerge --info in the bug.  Here it is, in case anyone
needs to compare notes....

Tried to submit upstream, but the only e-mail address I could find was for the
web master of the kde site that hosts the kmplayer home page.  Hope that's the
right place to send things....

Okay.  Discovered that kmplayer is on KDE's bugzilla.  Submitted upstream. 
From reading the bug there, it looks like they may have already fixed this in
the latest SVN.  I couldn't tell for sure...

Reopened KDE bug 133214 since closed bugs may not get enough attention. Robert,
could you attach the patch on KDE Bugzilla as well please?

Okay.  Patch submitted upstream.  Looks like Koos is on top of it.

Thanks for the patch Robert. Likely not the only application having this
compatibility problem...


Arch teams, please stabilize kmplayer-0.9.4a-r1 asap.

x86 stable

Compiles on amd64 no errors and no collision. 
I can still watch all my video's so I'd say amd64 is good to mark it stable.
