Hello,

To continue my story, please let me say that I have successfully compiled Mplayer after removing
completely FFmpeg from my system. However, the original problem, that is, the decoding of
MP3 files is still there. I have used a 64bit version of mgp123 to play some MP3 file and there
is absolutely no problem:

$ /opt/gnu/bin/amd64/mpg123 -v song.mp3 
High Performance MPEG 1.0/2.0/2.5 Audio Player for Layers 1, 2 and 3
    version 20091026000000; written and copyright by Michael Hipp and others
    free software (LGPL/GPL) without any warranty but with best wishes
Decoder: x86-64 (SSE) <------------------------------------------------------------------------------------------

Playing MPEG stream 1 of 1: song ...
Title:   Without you                     Artist: Some Artist                  
Comment:                                 Album:

[0:31] Decoding of Without you (Nilson).mp3 finished.

Now when I play the same file with the 64bit version of mplayer, this what mplayer reports:

==========================================================================
Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
dec_audio: Allocating 4608 + 65536 = 70144 bytes for output buffer.
mp3lib: using generic C decore! <--------------------------------------------------------------------------------------------------
MP3lib: init layer2&3 finished, tables done
MPEG 1.0, Layer III, 44100 Hz 128 kbit Joint-Stereo, BPF: 417
Channels: 2, copyright: No, original: Yes, CRC: No, emphasis: 0

Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)
==========================================================================

while the 32bit version reports the following:

==========================================================================
Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
dec_audio: Allocating 4608 + 65536 = 70144 bytes for output buffer.
mp3lib: using 3DNow!Ex optimized decore!  <----------------------------------------------------------------------------------
MP3lib: init layer2&3 finished, tables done
MPEG 1.0, Layer III, 44100 Hz 128 kbit Joint-Stereo, BPF: 417
Channels: 2, copyright: No, original: Yes, CRC: No, emphasis: 0
AUDIO: 44100 Hz, 2 ch, s16le, 128.0 kbit/9.07% (ratio: 16000->176400)
Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)
==========================================================================

So it seems the decore is not the appropriate one. Comments, suggestions?
