Comment:

 Thank you. I'll build from git-master.

 What is the expected behavior, please - should `-skip_frame nokey` skip
 everything but IDR frames?

 It appears that `ffprobe -show_frames` identifies all I or IDR frames as
 `key_frame=1`.
 I assumed that `-skip_frame nokey` would skip those same frames.
 It appears that `-skip_frame nokey` skips all but IDR.

 It's that difference in behavior that surprised me.
