Как настроить ffmpeg в Ubuntu для преобразования файла 3GP в PCM WAV?

Я использую Ubuntu 10.04. Мне нужно конвертировать .3gp файл в формат PCM WAV. Я использую ffmpeg для этого.

Когда он устанавливается из репозитория с помощью, aptitude install ffmpegон устанавливает базовую версию, и я не могу конвертировать то, что мне нужно.

Я установил последнюю версию yasm версии 1.1.0 и новейшую версию x264 - 0.125.2208. После этого я получил FFmpeg с помощью мерзавца из официального сайта с git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg.

Я попытался настроить ffmpeg самостоятельно, используя:

./configure --enable-gpl --enable-version3 --enable-postproc  --enable-nonfree --enable-swscale --enable-pthreads --enable-libmp3lame  --enable-libx264 --enable-libopencore-amrnb --enable-libopencore-amrwb 

Тогда: time make && make install.

До этого времени все было хорошо. После преобразования с

ffmpeg -i audiotest.3gp -f s16le -ar 8000 -acodec pcm_s16le audio.wav 

Я хотел проверить информацию об этом файле PCM * .wav (ffmpeg -i audio.wav) и получил эту ошибку:

Как следует из первого сообщения об ошибке:

Format aac detected only with low score of 1, misdetection possible! 

он неправильно определяет тип входного файла. Укажите формат входного файла, используя -fопцию следующим образом:

ffmpeg -f s16le -i input.wav 

и это должно работать лучше.

Однако, если вы просто хотите получить информацию о файле, вы должны использовать вместо этого FFprobe . Обычно он поставляется с FFmpeg, имеет аналогичные параметры и предоставляет информацию в гораздо более удобном для анализа формате. В -show_formatи -show_streamsварианты должны дать вам наиболее всю необходимую вам информацию о файле.
