Bug Description

The current version of mplayer which is shipped with Ubuntu Trusty has broken support for png / alpha image output. This in turn breaks other packages, in particular the LiVES application (http://lives.sourceforge.net).

Tested with mplayer version 2:1.1+dfsg1-0ubuntu3.

To reproduce:
mplayer -vo png:alpha <any_video_file>.

Expected result: produces numbered sequence of png images (works with the :alpha omitted).

Actual result: error and no ouput produced.

I believe this can be fixed very simply by adjusting the compilation options for mplayer.
