Comment (by pkerling):

 Yes, the problem is that ffmpeg seeks past the requested point and not
 before it. But it's probably not that easy - unfortunately, the suggested
 solutions do not work. Adding `AVSEEK_FLAG_BACKWARD` does not change
 anything. Going back to older versions only makes it worse, depending on
 the seek time an entirely black PNG file is sometimes written. I tried to
 go to fcfb66b but could not find this revision in the ffmpeg git
 repository. Instead, I went back to both one commit before 16b0c92
 (11c5f43) and 0e0cefb.

 On another note, I can find none of the mentioned commits except 16b0c92.
 Which repository should I be looking at?
