[Ffmpeg-devel] FLV to H.263 or related format

[yj]

Hi,
I want to convert FLV to H.263 or related format
under
embedded platform since it doesn't support decoding
FLV format.
is it complicated for the conversion?
Can ffmpeg support the convertion?
If so, how to implement this function?
I've tested by using ffmpeg command:

ffmpeg -i test.flv -ab 56 -ar 22050 -b 500 -r 15 -s
320x240 -acodec mp3 test.mp4

but the ffmpeg only tells me:
Unsupported codec for output stream #0.1

The following are the information dumped from ffmpeg
during the execution of the command:

FFmpeg version SVN-r6315, Copyright (c) 2000-2004
Fabrice Bellard
 configuration: --prefix=/ffmpeg
 libavutil version: 49.0.0
 libavcodec version: 51.14.0
 libavformat version: 50.5.0
 built on Sep 22 2006 09:51:34, gcc: 3.3.2 20031022
(Red Hat Linux 3.3.2-1)

Sees that stream 1 comes from film source: 1000.00
(1000/1) -> 30.00 (30/1)
Input #0, flv, from 'test.flv':
  Duration: 00:01:26.0, start: 0.000000, bitrate: N/A
  Stream #0.0: Audio: mp3, 44100 Hz, stereo
  Stream #0.1: Video: flv, yuv420p, 720x484, 30.00
fps(r)
Output #0, mp4, to 'test.mp4':
  Stream #0.0: Video: mpeg4, yuv420p, 320x240, q=2-31,
0 kb/s, 15.00 fps(c)
  Stream #0.1: Audio: 0x0000, 44100 Hz, stereo, 96
kb/s
Stream mapping:
  Stream #0.1 -> #0.0
  Stream #0.0 -> #0.1
Unsupported codec for output stream #0.1

can anyone help me for this problem?
Thanks a lot.
