Getting amr/3gp support to mplayer

HOWTOs 8 Comments »
Due to license reasons the support of 3GP is not implemented in mplayer. You can play 3GP movies in mplayer but you wont hear sound.

Now you have to compile the amr support into your libavcodec.

UPDATED
Check comments first for newer informations regarding opencore-amr

First of all you have to download the source of mplayer.
You can get the latest version here: http://www.mplayerhq.hu/design7/dload.html

Now you have to download the following files, unzip and rename them:
# cd MPlayer*/libavcodec
# wget http://www.3gpp.org/ftp/Specs/latest/Rel-5/26_series/26073-530.zip
# unzip 26073-530.zip
# unzip 26073-530_ANSI_C_source_code.zip
# mv c-code amr

# wget http://www.3gpp.org/ftp/Specs/latest/Rel-5/26_series/26104-540.zip
# unzip 26104-540.zip
# unzip 26104-540_ANSI_C_source_code.zip
# mv c-code amr_float

# wget http://www.3gpp.org/ftp/Specs/latest/Rel-5/26_series/26204-530.zip
# unzip 26204-530.zip
# unzip 26204-530_ANSI-C_source_code.zip
# mv c-code amrwb_float

Now just go one folder up and configure it:

# cd ..
# ./configure

You should now see the following output:

Checking for AMR narrowband ... yes 
Checking for AMR narrowband, fixed point ... no (disabled by amr_nb)
Checking for AMR wideband ... yes



Now you just have to make & make install it... Thats it!

mplayer and mencoder are now ready to decode sound of 3GP files!

    small correction regarding amr-wb
    26204-530.zip archive has been updated and replaced with new one 26204-540.zip

    I did same but still in ./configure of mplayer says

    Checking for libopencore_amr narrowband ... no
    Checking for libopencore_amr wideband ... no

    I got mplayer-checkout-2010-02-26 snapshot.
    Copied the zip files to libavcodec directory of mplayer & extracted them there also renamed folder c-code in each case.
    What do you suggest ?

    Looks like you're missing the opencore_amr library..
    Try installing it first.

    You can get it here:
    http://sourceforge.net/projects/opencore-amr/

    Or check the package-repository of your linux distribution

    I got opencore-amr-0.1.2.tar.gz & now i have

    Checking for libopencore_amr narrowband ... yes
    Checking for libopencore_amr wideband ... yes

    Just one thing.
    Does this mean that the steps you have mentioned about zipping three files where last one should be 26204-540.zip (corso said) are not necessary ?
    OR
    open-core library is additional ?

    Thank You for prompt reply.

    Well, this blogpost is a bit older, so i can't really tell you more about the opencore lib.

    Maybe it wasn't necessary at that moment, or i had it already installed.
    Maybe there is now another way with libopencore to compile MPlayer with such a support

    This is for information of all that in latest source snapshot of mplayer ( 26 feb 2010 onwards ) you need ONLY opencore-amr-0.1.2.tar.gz only.
    I am using ubuntu 8.04 & I compiled mplayer tarball just after opencore-amr install . It worked . I had booted ubuntu 8.04 from live cd si it was like fresh install.
    Thank you Nils for your valuable help.
