 Summary of the bug: ffprobe fails with "error reading header"

 How to reproduce:

 The data is small (800b), so I attached a base64 command line to generated
 the data (I also attache the binary if it's more convenient).

 }}}

 Calling ffprobe (or ffmpeg) on the data seems to fail with a reading
 header issue:
