3gp sound?

[Morimando]

well managed to make mplayer play .3gp videos, but the sound is still missing. Does anyone know what to do?
There must be a way to make sound work with it...
oh and please if anyone
a) knows how and
b) is willing to explain it to me, please
c) do it in a way that i (pretty noob) will understand.. thanks.

what codec is the sound encoded with? You need to get the codec.

[Morimando]

ARM is the name of the thing.. or AMR

Amr probably narrow band.
2 possitibilities :
- install ffmpeg + etsi reference code to decode amr
- use avidemux2 cvs

[Morimando]

k ffmpeg comes with mplayer as standard i think... how do i insert the rest?

you have to fetch & install the etsi reference amr decoder in amr_float directory of ffmpeg
do a ./configure --enable-amr it will tell you what to do
(or use avidemux cvs, it is included)

[Morimando]

so that means i need ffmpeg from source not from ebuild, right?

yes
(or use avidemux2 cvs ebuild....)

[Morimando]

I C, okay i fetched ffmpeg CVS, fetched the 2 needed .zips for AMR, doing make after that make install and see what happenes
uhm i do not need to uninstall ffmpeg ebuild prior to this, do i?

damn "make" says it has no rule to make target 'amr_float/sp_dec.c' , which is (quite obviously) needed.. so make stops

edit: got this one..., trying second time on an "older" version of ffmpeg (CVS-snapshot couple of days old), because the CVS-version i tried hat an unlinked reference or so to the faac codec (which i don't want to install after all ^^) seems okay, only some unreferenced pointer-types and minor warnings (the kind one get's most times when compiling stuff ><) looks ok till now

okay ffmpeg installed correctly, but mplayer says the same as everytime:

[thebigslide]

You're probably missing something. Either configure --help and pick off the option you need or have a look at what ebuild --configures with by looking at a config.log in the build dir.

[mean]

you built a standalone ffmpeg that is amr aware
use ffmpeg, not mplayer

[Morimando]

*confused is*
well uhm mplayer makes use of ffmpeg to play videos... so if i built that ffmpeg with amr then it should work, shouldn't it?
@config i can't seem to find anything that relates to mplayer being built with amr

No, mplayer uses just a part of ffmpeg (libavcodec)
A release version of mplayer contains the libavcodec it uses, so it does not change anything to mplayer if you update ffmpeg
as it is compiled in.

You can build mplayer cvs with ffmpeg cvs but you have to copy the libavcodec directory into mplayer cvs libavcodec dir.
(MplayerCVS libavcodec directory is empty )

[Morimando]

What i do at the moment is the following:
I got myself the mplayer-source, inserted the amr directories into mplayer-src/libavcodec/dirname, then looked at the available ./configure options and modified them like this:
