I believe the intent of https://github.com/AOMediaCodec/av1-avif/blob/master/testFiles/Netflix/avis/alpha_video.avif is to be a file with both 'avis' and 'avif' brand support, including an alpha channel associated with the primary image item.
The file contains both a primary image with
item_ID
4:as well as an alpha image with
item_ID
3:But the
iref
box which should associate the alphaitem_ID
(3) -> primary imageitem_ID
(4) instead associatesitem_ID
(3) ->item_ID
(0)I believe the fix is simply changing the byte at offset 0x103 to 0x04 as in alpha_video_fixed.avif.zip.
