Vorbis missing extradata

Description

Audio fails to play.

Interestingly, a 10MB cut of the file does play. In that case the header mismatch error remains, but the missing extradata error goes away.

File plays with latest VLC. It also played with old version of LAV Filters 0.68.1 (which uses FFmpeg) from early 2016. So regression in FFmpeg occurred around that time.
