    initial v1  
    11These type of files fail into a category where the main background does not change often and it is appropriate for them to have one or just a few keyframes.

    3 first_keyframe_only_confused.mov and first_keyframe_only_count.mkv are the same as evbpic.avi in the sense they all only have 1 first keyframe. They also can be seeked into easily and quickly if little more work is performed when seeking.

    5 no_keyframes_filecopy.avi has no keyframes and so the first frame must be artificially marked as a keyframe for it to work and then proceed with exact timestamp seeking on it.

    77The same problem is going to exist on files where the keyframes are sparse, but more than one, in that you will notice large jumps when trying to seek with ffmpeg.
