Comment (by Cigaes):
Why do you want the frame number for? The frame number is a fragile thing:
remuxing to a format that does not support variable frame rate or encoding
to a codec that aggressively drops frames may change it.
Since last week, the drawtext filter can be used to print the exact
timestamp of each frame. Timestamps are the correct way of addressing
frames.
