[Mlt-devel] MLT/Shotcut Specification: ID stability

[Allan R. <al...@re...>]

Hey folks,

A bit of a strange question, but I don't see any mention of this in the MLT
documentation. Is there any central specification or convention on how NLEs
handle IDs? I know the naming conventions tend to be a bit different, e.g.
Shotcut (producer0, producer1...), but is there anything with regards to ID
stability? Specifically, are NLEs "allowed" to change IDs if they're
already set? e.g. a user adds some resource in the middle of the playlist,
is there any restriction in the spec that the NLE implementation should
only create a unique ID for that specific resource without modifying the
other IDs?

The motivation here is that I'm looking for a stable identifier for assets
(images, video clips, etc.) to map to uploaded assets (e.g. AWS S3) and
want to make sure it covers as many MLT-backed editors as possible. If this
isn't in the MLT spec, is it something worth considering?

Thanks!

Cheers,
Allan
