Tim Allison commented on TIKA-4509:
-----------------------------------
My proposal would be to add this to tika-mimetypes.xml:
{noformat}
<mime-type type="image/avif-sequence">
<_comment>AV1 Image File with animation</_comment>
<acronym>AVIF</acronym>
<tika:link>https://en.wikipedia.org/wiki/AV1#AV1_Image_File_Format_(AVIF)</tika:link>
<magic priority="60">
<match value="ftypavis" type="string" offset="4"/>
</magic>
<sub-class-of type="image/avif" />
</mime-type> {noformat}
> AVIF animation detected as video/quicktime
