Now I can watch video without sound, I found, that someone was able to
hear sound (23.11.2004 - playing 3GP/H2.63/AMR files thread).
I've edited codecs.conf
videocodec ffh263
(..)
format 0x33363273
but when I add:

audiocodec ffamr
  format 0x726D6173
  fourcc "samr"
  dll "amr_nb"

even video doesn't work.

To add support for amr_nb you have to recompile mplayer (exactly
libavcodec) with amr_nb fixed.

This is instruction (from another thread):

Ok.. I had executed following steps in-order to play
amr_nb audio. [ steps - just for archive]

1. cd $mplayer-source
2. rm codecs.conf.h
3. cd etc/codecs.conf.h
Edit it and add

audiocodec ffamr
  format 0x726D6173
  fourcc "samr"
  dll "amr_nb"

4. Recompile mplayer agian..as codecs-cfg parser
generated codecs.conf.h and it is getting included
some-where...:-). Just updating codecs.conf on target
is *not* working...

5. Anyway, I am able to play 3gp file amr_nb on OMAP
board..Thanx for help.
