Comment:

 I too see that the text file is smaller and it runs faster. But In test2
 file you will still see information about frames that are not key i.e
 [frame]
 media_type=video
 '''key_frame=0'''

 I would have expected that no lines with key_frame=0 should be present in
 the output. I also see that there are lots of warnings when running with
 skip_frame nokey options: like
