CMAF video example.

Hi, can someone please provide a CMAF video example?
Thanks.

@sr1990 At this time, CMAF is not a supported format by the C2PA, which is why there are no examples.

We have an active workstream around streaming media, and this is certainly part of that.

Hi @lrosenthol Thanks for the information.
Do you have an example fmp4 file as per https://c2pa.org/specifications/specifications/2.0/specs/C2PA_Specification.html#_auxiliary_c2pa_boxes_for_large_and_fragmented_files
where

For fMP4 assets which are stored as a single flat MP4 file with a single 'moov' for all tracks and then one 'moof'/'mdat' pair for each fragment:

One auxiliary 'uuid' C2PA box with box_purpose set to 'merkle' as described below shall be included immediately preceding each 'moof' box.
