Since the commit of https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/701e8b42e12ad625c64ceae2252a..., vc-1 parser erroneously flagged every packet as keyframe. If you recompile the tool with that commit reverted, you will get the expected result.
The first shows the result with that commit. The second shows the result without that commit.
