Could you provide a sample that does not seek to a keyframe with
ffmpeg -ss x -i input out.png
(I tested this yesterday on random mpeg2video samples and afaict,
it did work.)
Sure, here's a link to a sample video I'm testing with (sorry, it's
785 MB):

I did some visual inspection seeking here and there with my own app and the
above file does not seem to be a problem. When I get a chance I will look at
the numbers to check the accuracy. Just doing the visual inspection may not
be enough.
