New description:

 Summary of the bug:

 "ffprobe -of XXX" prints something that might contain XXX but doesn't
 actually write any data.

 How to reproduce:
 {{{
 % ffprobe 01.ogg
 [ comprehensive data dump ]

 % ffprobe -of json 01.ogg 2>/dev/null
 {

 }
 }}}

 This happens with MP4 files too so looks like a generic problem.

Comment:

 Report fixed. Sorry for mistakenly writing "ffmpeg" instead of "ffprobe"
 in the description.

 Using -hide-banner or not doesn't affect the output; in fact further
 testing shows that all the verbosity goes to stderr and stdout is empty.
