[libav-api] H264 encoded video cannot be played by Windows Media Player 12

I have a H264 encoded video (self-generated using libav) which cannot be
played by Windows Media Player 12 (Windows 7 Professional SP1), but by other
video players such as VLC.

Unfortunately Media Player (version 12.0.7601.18526) does not provide any
(error-)information why the video isn't played - the player is in play mode,
the progress bar flickers, but unfortunately nothing to see. 

The non-playing video of interest can be found here:

Used H264 analysis tools indicate no errors, so it seems that the file
content is not completely wrong - maybe only a flag needed by Windows Media
Player is not set correctly.


Thanks in advance for any kind of helpful response.
