Title: heif sequence has mimetype video/mp4
Post by: kiefermat on June 08, 2020, 11:23:16 AM

Hi,

when extracting metadata of a heif sequence file, exiftool correctly reports the major brand as "High Efficiency Image Format sequence" but the mimetype as "video/mp4". I think it should be "image/heif-sequence" instead?

Sample file can be found here: https://github.com/nokiatech/heif_conformance/blob/master/conformance_files/C026.heic

exiftool C026.heic

Code Select


...
MIME Type                       : video/mp4
Major Brand                     : High Efficiency Image Format sequence (.HEIFS)
...

I tested this behaviour with exiftool 11.99 on a Mac.

Would be nice, if you could have a look at it.

Matthias
