Current code will call avpriv_set_pts_info() for each video frame,
possibly setting a different timebase if the stream framerate changes.
This violates API conventions, as the timebase is supposed to stay
constant after stream creation.

If input packets have timestamps, they will be propagated to output
frames by the decoder, so at best this block does not do anything.
There can also be an arbitrary amount of delay between packets sent to
the decoder and decoded frames (e.g. due to decoder's intrinsic delay or
frame threading),

support for animated WebP had been proposed twice in the past [1][2].

Adds support for decoding of animated WebP.
The WebP parser now splits the input stream into packets containing one frame.
The WebP decoder adds the animation related features according to the specs:
