[FFmpeg-devel] [PATCH] avformat/mov: ignore old infe box versions

[James Almer <jamrial@gmail.com>]

Some files with no image items have them, and were working prior to the recent
HEIF parsing overhaul.
Ignore such boxes instead, to recover the old behavior.

Fixes a regression since d9fed9df2a9e70c9375d3b2591db35c09303d369.
