Comment (by DonMoir):

 By exact timestamp seeking I mean if you request an arbitrary time, it
 will make a best effort to get there and not stop just because the file
 may only have one first keyframe.

 I don't create the files but many files exist that have this problem with
 ffmpeg. Mostly when you run into a case like this, it tends to be a simple
 file that can be easily seeked to at any position with a little extra
 work. This is the users expected behavior regardless of how it's been
 encoded. It's rare for a high res file to have this problem but if it does
 it can be dealt with appropriately.

 You try ffplay or MPlayer and see how well they do. I already have it
 handled in my own app. I don't mind if it's a higher level step
 personally, but it could give ffmpeg a better and more expected behavior.
