Comment (by duggaraju):

 Attached is the file. This is the sample wildlife.wmv file present in
 windows 7.

 ffprobe -skip_frame nokey -select_streams v -show_frames wildlife.wmv

 works fine as expected.where as:

 ffpropbe -i wildlife.wmv -b:v 512k wildlife.mp4
 ffprobe -skip_frame nokey -select_streams v -show_frames wildlife.mp4

 results in all the frames being dumped and the output has a bunch of
 warnings.
