Title: Add ability to seek streams without keyframes

Hello. I have some mpeg files without keyframes (I think there are only quasi-keyframes on scene transitions). I wasn't able to seek them without this small modification. Of course seeking to non-keyframes causes a temporary glithes, but it's a much lesser problem than inability to seek at all.
