[MPlayer-users] video plays with grey (or gray) screen

[Michael Rasmussen]

I've a freshly created video that will play fine when uploaded to YouTube or when editing in kdenlive. 
When I attempt to play the source file I get just the audio and a grey screen.   mplayer also becomes unresponsive to keyboad/mouse input after playing the clip.

What needs to be done to play correctly?

Here is my mplayer version, the start of the output when I run mplayer from the command line and information about the video file as described by mediainfo.


mplayer version: 2:1.0~rc2-0ubuntu19

When running mplayer from the command line the output is:
