 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:

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

 Thanks
