The last line explains it all.
Code:
Unsupported codec for output stream #0.1
Your version of ffmpeg doesn't support that format, at least not under that name. The precompiled packages included in many distributions don't, and can't, include support for codecs that have IP restrictions on them.

First run ffmpeg -formats and ffmpeg -codecs to see what your current version supports, and using what name. If you don't find what you want there, then you will probably need to find or compile a version that does include support for it.

Edit: I see that the codec in question is AAC. This is first of all one of the restricted formats I mentioned, and second, ffmpeg doesn't handle it internally. It can use the external faac library for encoding, but only if support for it has been compiled in, which yours hasn't. If it had, you'd see --enable-libfaac listed in the configuration flags.

But this is only when you need to re-encode the streams in question. In this case though it looks like you may be able to simply keep the current audio stream, assuming it's legal for the output 3gp format. If so, try adding -acodec copy to your command to keep the current stream as-is.

Bitstream filters:
 text2movsub remove_extra noise mov2textsub mp3decomp mp3comp mjpegadump imxdump h264_mp4toannexb dump_extra
Supported file protocols:
 file: gopher: http: pipe: rtp: tcp: udp:
Frame size, frame rate abbreviations:
 ntsc pal qntsc qpal sntsc spal film ntsc-film sqcif qcif cif 4cif

Note, the names of encoders and decoders do not always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported. For example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats it is even
worse.
I read about 3gp container format which says
Quote:
The 3GP file format stores video streams as MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264), and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC v1 or Enhanced aacPlus (HE-AAC v2).
Also i tried with different input file
Code:
Input #0, avi, from 'advice before meeting ramgopal.mpg':
  Duration: 00:00:21.04, start: 0.000000, bitrate: 953 kb/s
    Stream #0.0: Video: mpeg4, yuv420p, 352x288 [PAR 1:1 DAR 11:9], 25 tbr, 25 tbn, 25 tbc
    Stream #0.1: Audio: mp3, 44100 Hz, stereo, s16, 320 kb/s
Output #0, 3gp, to 'advice':
    Stream #0.0: Video: h263, yuv420p, 352x288 [PAR 1:1 DAR 11:9], q=2-31, 200 kb/s, 90k tbn, 25 tbc
    Stream #0.1: Audio: 0x0000, 44100 Hz, stereo, s16, 64 kb/s
Stream mapping:
  Stream #0.0 -> #0.0
  Stream #0.1 -> #0.1
Unsupported codec for output stream #0.1
Seems I will have to compile ffmpeg from source . I wish there was a binary available .

Finally I did it.
It seems ffmpeg was installed without libopencore libraries. from repositories you don't get full fledged compilation. Previously I had medibuntu but it failed in amr audio. By the way , I am using ubuntu 10.04 .

I had to build ffmpeg from tarball.
I have compiled with lot of options
Code:
./configure --enable-avfilter --enable-avfilter-lavf --enable-vdpau --enable-bzlib --enable-libgsm --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-pthreads --enable-zlib --disable-stripping  --enable-runtime-cpudetect --enable-gpl --enable-postproc --enable-swscale --enable-x11grab --enable-libdc1394 --enable-libopencore-amrnb  --enable-libopencore-amrwb --enable-version3 --enable-libfaac --enable-nonfree  --enable-libmp3lame --enable-libx264 --enable-gpl --enable-libxvid
Also while converting to 3gp you have to be specific about
Code:
(1)frame size(-s option)
(2)audio sampling rate (-ar 8000 only)
(3)audio bitrate (4.75k, 5.15k, 5.9k, 6.7k, 7.4k, 7.95k, 10.2k or 12.2k)
(4)channel (-ac 1 i.e only mono)
