The current spec says in section 2.1:

A file conformant to this specification satisfies the following:

However, strictly speaking, when the file is encrypted per section 4, the AV1SampleEntry is transformed into an Encrypted Visual Sample Entry (encv). We should probably clarify the above sentence by saying:

  • It SHALL contain at least one track using an AV1SampleEntry, possibly transformed by encryption as specified in ISOBMFF

A similar change should be made to section 3
