-/* A test program for the Rockbox version of the ffmpeg FLAC decoder.
-
- Compile using Makefile.test - run it as "./test file.flac" to decode the
- FLAC file to the file "test.wav" in the current directory
-
- This test program should support 16-bit and 24-bit mono and stereo files.
-
- The resulting "test.wav" should have the same md5sum as a WAV file created
- by the official FLAC decoder (it produces the same 44-byte canonical WAV
- header.
