audecode

audecode exposes audio decoding functionality as a (buffered) binary-stream interface. It can convert the output to the desired sample format (sample rate / sample width / channel downmixing).

Data is fed to the library using a read callback function, and the output is read using a simple read()-like interface.

Installation

This library depends on the libav* set of libraries libavcodec, libavformat, libavutil (either from ffmpeg or libav). On a Debian-based system, the following command should install all the required dependencies:

$ sudo apt-get install libavcodec-dev libavformat-dev \
    libavutil-dev libavresample-dev

Note that if you are using the ffmpeg packages you might have to replace libavresample-dev with libswresample-dev.

The code is built using autoconf, so the standard installation procedure applies:

$ sh ./autogen.sh
$ ./configure
$ make && sudo make install

Caveats / Limitations

Only one audio stream can be extracted from the input: this will be the `best' one according to libav.
