 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:

Comment:

 To read samples you need to use data[0] for packed sample formats.
 And for planar sample formats use extended_data[X] where X is channel
 number.

 Of course it does not work. Deint 2 (adaptive) is broken in recent
