Comment (by t.rapp):

 As "ffprobe -f lavfi movie=..." doesn't seem to support seeking (e.g.
 "-read_intervals 30%+2") it would be great if filter options could be
 specified explicitly in ffprobe.

 My use-case is detecting frame interlaced property using "idet" filter at
 specific seek points (I don't want to scan the whole, large input file).
 So it would be nice if something like the following command would work:

 {{{
 ffprobe -i some-input-file.avi -filter:v idet -show_entries frame_tags \
   -read_intervals %+2,05:00%+2,10:00%+2,20:00%+2
 }}}
