[MPlayer-users] ffprobe reporting errors, but mplayer playing mp4 file just fine?

[Albretch Mueller]

 I have always thought mplayer is based on ffmpeg and ffmpeg uses
ffprobe to get data off files in order to process them, but when I
ffprobe media files I get errors even if (in some cases) the files
play just fine using mplayer
~
 The kinds of errors I am getting look like this:
~
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '<path to mp4 file>':
  Duration: 00:06:17.70, start: 0.000000, bitrate: 823 kb/s
    Stream #0.0(und): Invalid Codec type 28, 30 tbr, 30 tbn, 30 tbc
    Stream #0.1(und): Invalid Codec type 86018
Unsupported codec (id=1630826605) for input stream 1

 the version of ffprobe I have in my system is:
~
$ ffprobe -version

 Is mplayer using codecs from another location? How can I make ffmpeg,
ffprobe and mplayer use the same codecs? How can I coordinate their
configuration files?
