That may be impossible. Just do timestamp seeks directly (and also use
AVSEEK_FLAG_BACKWARD).
That might be unreliable too (depending on the format), and the only
absolutely reliable way to do sample-exact seeking is decoding the file
from the start and skipping samples until you reached the target.
