Estou usando o Ubuntu 10.04. Eu preciso converter um arquivo .3gp para PCM WAV. Estou usando o ffmpeg para isso.
Quando ele é instalado do repositório usando aptitude install ffmpeg , ele está instalando uma versão básica dele e não consigo converter o que preciso.
Instalei o último yasm ver.1.1.0 e o mais novo x264 - 0.125.2208. Depois disso, obtive o ffmpeg usando o git da página oficial com git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg .
Eu tentei configurar o ffmpeg sozinho usando:
./configure --enable-gpl --enable-version3 --enable-postproc
--enable-nonfree --enable-swscale --enable-pthreads --enable-libmp3lame
--enable-libx264 --enable-libopencore-amrnb --enable-libopencore-amrwb
Então: time make && make install .
Até agora tudo estava bem. Após a conversão com
ffmpeg -i audiotest.3gp -f s16le -ar 8000 -acodec pcm_s16le audio.wav
Eu queria verificar as informações sobre este arquivo PCM * .wav (ffmpeg -i audio.wav) e recebi este erro:
~# ffmpeg -i audio.wav

Alguém pode me ajudar com isso? O que estou fazendo errado?
