Can't you set the video's time scale such that an integer increment corresponds to an amount of real time that's relevant to your situation?
(This is more or less what I did when I had to sync 12.5Hz video with 1kHz dynamic data; I reconstructed new QuickTime movies with a time scale of 12500)

Of course I know next to nothing about libav O:^)
