-------------------------------------
Summary: HeifParser should accept image/avif
Key: TIKA-4870
URL: https://issues.apache.org/jira/browse/TIKA-4870
Project: Tika
Issue Type: Improvement
Reporter: Dominik Schmidt
AVIF files reach no parser today. HeifParser claims image/heif,
image/heif-sequence, image/heic and image/heic-sequence, nothing else in
tika-parsers claims image/avif, and its mime entry declares no sub-class-of
image/heif, so an AVIF is detected and then handed to no one: no dimensions, no
EXIF, no XMP. Detection was added in TIKA-3193 and nothing ever picked it up
for parsing.
The container is the same ISO-BMFF and the metadata sits in the same places.
HeifXmp locates XMP generically through meta/iinf/iloc, which is where AVIF
puts it as well, and metadata-extractor reads HEIF item properties for AVIF
too, so adding MediaType.image("avif") to the parser's supported types is most
of the work; what it needs is a fixture and a check of which properties
actually come out.
Once that is in, the Motion Photo work from TIKA-4869 should be checked against
it: AVIF is one of the three primary image formats the Motion Photo format
allows, alongside JPEG and HEIC, and its video sits in the same trailing mpvd
box, so the same code should emit it. There is no test for that today.
Detection of animated AVIF is a separate question and is tracked in TIKA-4509.
