@rbouqueau please check if you can create the content
I can create but marked as low priority at the moment.
Agree with the issue creator, I'd also love to see an official example. We're currently looking into using selectionPriority in our manifests, and this would help us a lot.
A way of generating and playing these back. The use case we're seeing is deterministic audio track selection when multiple codecs are used with the same role of "main"
Please also take into account the v4.3 and v5 on signaling of multiple Adaptation Sets.
A short description of the use case for the new test content.
This test content is supposed to demonstrate the usage of the
selectionPriority
attribute on AdaptationSet level. In https://github.com/Dash-Industry-Forum/dash.js/pull/3751 we implemented this feature to dash.js based on unit tests and a manually created test vector.It would be nice to verify the correct behavior based on an official DASH-IF test vector.
Test content requirements
General description and requirements
selectionPriority
attribute. Ideally the AdaptationSets differ in codecs, for instance AVC and VP9 for video and AAC and Opus for Audio.DASH-IF documents and links
Additional questions/comments
Right now we are ignoring the
group
attribute so it might be good to create additional test vectors for this as well.
