Thanks a lot. According to your suggestion the previous 'unknown encoder
h263' is gone after compiling ffmpeg from source. But, now getting new error
with audio codec. If I use the command with codec "aac", then I don`t get
any sound from my converted 3gp file:

/opt/ffmpeg-0.6.1/ffmpeg -i TV_output -s qcif -vcodec h263 *-strict
experimental -acodec aac** *-ac 1 -ar 8000 -r 25 -ab 32 -y TV_output.3gp

After using this, I can play my video but no audio.
