It only calls chain for the codec_data (which is normally out-of-band
data). Some formats contain that chunk of data at the beginning of the
stream (in-band) and some others not (out-of-band).
The libtheora library requires the user to pass that data to be
decoded before giving it any other data. That's why it's done there.
