When trying to open a particular WAV file (which I'd just decoded from a
FLAC file using the "flac" tool), ffmpeg produces a string of errors,
starting with "Not a valid DCA frame". This is with the latest source from
git:

your FFmpeg version to the newest one from Git. If the problem still
occurs, it means that your file has a feature which has not been
implemented.

I'll attach a sample of the file, which is enough to trigger the issue.
