Yup!
And if you include how to go the other way (to mpg or avi) aswell, that'd be great.

Why is this posted as a HOWTO when all it contains is a question? And yes, i'd be much interested in a tutorial to do this.

|

Here's a brief HOW-TO to 3gp and Gentoo.
Playing 3gp files
Helix player plays 3gp-files without a problem, at least with Real-codecs. I'm not sure if they are needed.
Helix Player is in portage (helixplayer and helixplayer-bin):
You can make mplayer play 3gp files too, but sound won't work. Mplayer doesn't recognize all 3gp files by default. You need to add a line to: /usr/share/mplayer/codecs.conf
ADD:
format 0x33363273
AFTER:
videocodec ffh263
Coverting other formats to 3gp
If you wan't to convert videos to 3gp to watch them on your phone, you need to emerge the latest ffmpeg (0.4.9_pre1). If you wan't the sound to work, you need to download the AMR-sound sources and make some changes to the ebuild.
As root, first you need to download the amr sources to /usr/portage/distfiles:
| Code: | cd /usr/portage/distfiles
wget http://www.3gpp.org/ftp/Specs/archive/26_series/26.104/26104-510.zip |
Then you need to edit the ffmpeg-ebuild:
| Code: | nano -w /usr/portage/media-video/ffmpeg/ffmpeg-0.4.9_pre1.ebuild
|
ADD:
mkdir ./libavcodec/amr_float
cd ./libavcodec/amr_float
unzip /usr/portage/distfiles/26104-510.zip
unzip 26104-510_ANSI_C_source_code.zip
cd ../
AFTER these lines:
src_unpack() {
unpack${A} || die
cd ${S}
Then REPLACE this line:
myconf="${myconf} --disable-opts --enable-pp --enable-gpl"
with this one:
myconf="${myconf} --disable-opts --enable-pp --enable-gpl --enable-amr_nb"
Then you can emerge ffmpeg-0.4.9_pre1:
| Code: | | emerge /usr/portage/media-video/ffmpeg/ffmpeg-0.4.9_pre1.ebuild |
You can check if AMR-sound is enabled with:
Now you can convert videos to 3gp with ffmpeg. Ffmpeg doesn't do as many input-formats and can't handle erroneous files as wells as mplayer, so it might be a good idea to convert files to a lossless format first with mencoder and then to 3gp with ffmpeg. You can also run different output filters with mencoder, such as crop, brightness etc, check the mencoder man page. You can also resize the file allready in mencoder.
| Code: |
mencoder original_file.avi -oac pcm -ovc lavc -lavcopts vcodec=mjpeg -sws 2 -vf scale=176:144:2:100 -o small_file.avi
ffmpeg -i small_file.avi -ar 8000 -ac 1 -acodec amr_nb -vcodec h263 -s 176x144 -r 12 -b 30 -ab 12 new_file.3gp

Maybe the structure of the archive "26104-510.zip" has changed a little bit since the posting of this HOWTO.
To get the ebuild running I had to unzip "26104-510_ANSI_C_source_code.zip" (it's included in 26104-510.zip) like this:
| Code: |
mkdir ./libavcodec/amr_float
cd ./libavcodec/amr_float
unzip /usr/portage/distfiles/26104-510.zip
unzip 26104-510_ANSI_C_source_code.zip
cd ../

You're right, that file needs to be unzipped as well. It worked like that before, I just forgot that line.  |

Ok so I can make 3gp files using ffmpeg, but...
I can't get any sound when playing 3gp files on my computer, even though they have sound when played on a phone. I've tried xine, mplayer and realplayer 10 (and a few other things that don't even play the video part right), but I get the same results with all of them.
Has anyone managed to get these to play on their computer with audio working?

Not quite ... but some observations that my help someone else take a step forward.
I can also encode 3gp files now. I have installed ffmpeg 0.4.9_pre1 along with the 3GPP code for the amr_nb floating point codec. Although ffservser no longer works, encoding 3gp files seems better.
I also tried the amr_nb fixed point code and also the amr_wb code from 3GPP but could not get either to build with ffmpeg 0.4.9_pre1. I have not yet tried to find out why...
I still cannot play back the 3gp encoded files with audio. I get video but no sound. Mplayer comes closest to succeeding. ffplay crashes on any 3gp files that have audio - I have not spent any time exploring why yet.
Mplayer seems to be almost there, and I read of at least one person who has succeeded with it on the mplayer email lists. What I did was add the following to the codecs.conf file:
| Code: | audiocodec ffamr
info "3GPP amr codec"
status untested
format 0x726D6173
driver ffmpeg
|
Now when I try to play a 3gp file with audio MPLayer dies with the following message:
| Code: | MPlayer interrupted by signal 11 in module: init_audio_codec
- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
won't help unless you provide this information when reporting a possible bug.
|
However, it has detected the audio stream as follows:
| Code: | Audio bits: 16 chans: 2 rate: 8000
MOV: Found unknown audio atom damr (17)!
Fourcc: samr
|
and then says
| Code: | Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
|
just before it dies.
"ffmpeg -formats" reports the amr_nb codec as being present.
If I invoke Mplayer with the switch "-ac amr_nb" codec it reports:
| Code: | Forced audio codec: amr_nb
Cannot find codec for audio format 0x726D6173.
Read DOCS/HTML/en/codecs.html! |
The person who reported it working compiled libavcodec as part of Mplayer rather than using the ffmpeg shared library. I have not tried doing this yet. 
If anyone makes further progress with this I'd be keen to hear. |

| I've been able to get the fixed point code from 3GPP to build with ffmpeg now, but it seems to make no difference and I still can't get MPlayer to play the audio of 3gp encoded files. Still unable to get the amr_wb version to build ... |

|
|
OK I've got MPlayer to play back my 3gp files using the amr_nb codec.
I downloaded the latest source for MPlayer from CVS and also for ffmpeg, copying the libavcodec stuff into MPlayer. I extracted the 3GPP codec as directed in amr.c and then built MPlayer with all the defaults except with --prefix pointing to a local user space installation directory.
It plays the 3gp encoded files with the amr_nb codec fine.
Perhaps there is something about the way the MPlayer ebuild is configured that is a problem? I haven't yet looked.
There is also another way you can play them back. Install Quicktime 6. It runs fine under wine (I use CodeWeavers) and the audio for the 3gp encoded files also works.
So now I have two ways of playing then on my linux box.  |

Not offhand but here are a few projects you might take a look at:
KSyncML
MultiSync http://www.multisync.org/
syncml server in php http://nicolas.bougues.net/syncml/
I'd be interested to hear if you succeed, and also of any other projects people know of. |

Did you try Helix? At least I had sound on .3gp working right away with it. I'm using v. 0.3.0.116
I'm not sure if I installed some extra codecs but I don't think so. You should give Helix a try, it probably plays 3gp-files with sound out of the box. | Code: | | emerge helixplayer-bin |

Actually, Helix seems to play some 3gp-files fine with working sound, but some files it doesn't play at all and just reports:
The following components are required:
