Describe the bug

specifications.csv and hence the references page cite ISO/IEC 14496-12:2004 (and 15444-12:2004) for the ISO base media file format and note that they are available as a publicly available standard from ISO. MPEG-4 Part 12 has been updated several times since 2004, the last time in December 2020, and it is not a Publicly Available Standard either yet or anymore. JPEG 2000 Part 12 has been withdrawn in 2015.

To Reproduce

Steps to reproduce the behavior:

  1. Go to https://mp4ra.org/#/references
  2. Go to the row with name column entry ISO
  3. Click on the second link provided there, leading to http://standards.iso.org/ittf/PubliclyAvailableStandards/index.html
  4. Try to find any edition of ISO/IEC 14496-12 (MPEG-4) or ISO/IEC 15444-12 (JPEG 2000) there
  5. Find no result

Expected behavior

If the standard should still be available freely to the public, ISO or the respective Maintenance Agency (which is Apple Inc. in this case) should actually list and publish it on the linked page. Otherwise the link and note should be removed.

Yes, ISO withdrew 14496-12 from public availability without telling us, or even apologizing (along with a slew of other standards, including DASH). Apparently prior agreements mean little. We are trying to have a conversation.
