Just checked with ffmpeg' produced amrnb and amrwb files on 32bit: OK.

However people say ffplay isnt capable of playing such files on x86-64,
while mplayer and xine play them just fine.

> ffmpeg -i /home/thresh/file.avi -acodec amr_wb -ar 16000 -ab 12.65k -s
> 352x288 -ac 1 file.3gp

results in mplayer's :
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffh263] vfm: ffmpeg (FFmpeg H.263+ decoder)
==========================================================================
==========================================================================
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
AUDIO: 8000 Hz, 1 ch, s16le, 128.0 kbit/100.00% (ratio: 16000->16000)
Selected audio codec: [ffamrnb] afm: ffmpeg (AMR Narrowband)

and

>ffmpeg -i /home/thresh/file.avi -ar 8000 -ab 12.2k -s 352x288 -ac 1
>file.3gp

results in mplayer's :

Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffh263] vfm: ffmpeg (FFmpeg H.263+ decoder)
==========================================================================
==========================================================================
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders

Selected audio codec: [ffamrwb] afm: ffmpeg (AMR Wideband)

mplayer and ffplay are dynamically linked to ffmpeg libraries.
