This behaviour was how it was originally. See the sample attached to 
#7091. Before inversion, first frame on that file is not marked as KF 
but all remaining frames are.

If you streamcopy the FATE sample to a new CPK starting at a frame 
currently not marked as KF, with -copyinkf, you should see 
artifact/incorrect decoding in the output.
