Support choice of images/videos in a single canvas

[masaball]

Avalon Media System manifests use the Choice construct described in Cookbook recipe 33 to provide users with quality options. Currently this is an unsupported feature in Clover that prevents Avalon manifests from loading properly:

Clover currently requests the manifest and loads the object metadata but fails to parse the Body to request the actual .m3u8 file(s).

Even if there is no desire to provide full support for this, would it be possible to implement minimum handling to parse the Choice construct and request the first item in the list?

A +1 to this issue -- as we're working with the Internet Archive to update their IIIF infrastructure, including support for millions of A/V items, we're currently looking at using choice to handle the wide variety of files and derivatives that IA makes available for every A/V item.

However, this means that most items don't seem to render when I try them using Clover.

Here's an example manifest that doesn't seem to work in clover for the reasons above (with the caveat that this is currently just a test URL and some elements are liable to change):

FWIW, here's the production version of the manifest in the comment above:
https://iiif.archive.org/iiif/HHFBC_tapes_D54A/manifest.json
And this is what currently renders in the Clover interface

@masaball cleaning up some old issues here and closing this. This is now supported. Thank you for opening the issue!
