 When running ffprobe with the -print_format switch as json, it can produce
 invalid Unicode escaping. Snippet of JSON code attached to the ticket.

 ffmpeg 1.2 installed  via Homebrew.

 Python code used to call ffsnoop:
 cmnd = ['ffprobe', '-v', 'quiet', '-print_format', 'json', '-show_format',
 '-show_streams', path]
 p = subprocess.Popen(cmnd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
 out, err =  p.communicate()
 io = StringIO(out)
 info = json.load(io)

 Python code to reproduce with attached JSON:
