But you weren't testing Reimar's patches for FFmpeg

<http://ffmpeg.org/pipermail/ffmpeg-devel/2013-August/146996.html>

and MPlayer

<http://lists.mplayerhq.hu/pipermail/mplayer-users/2013-August/086444.html>

in the aftermath of

<http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=bf36dc50ea448999c8f8c7a35f6139a7040f6275>

as you got these messages, were you?

Actually, it is the libavcodec h264 software decoder that finally gets 
to decode the video here. This is not what I would like to happen, but 
nevertheless, how do you achieve this fallback behavior in MPlayer?
