Please ask your question
I have understood that codec switching is at the moment not supported and that #1528 is planning to support it in v3.3.

I was wondering if you are considering support for the "Switching across Adaptation Sets" feature as described in https://dashif.org/docs/DASH-IF-IOP-v4.2-clean.pdf, chapter 3.8.

In essence, the manifest would use a Supplemental Property to signal which Adaptation Sets can be switched to/from.

As an example, a content author may signal that seamless switching across an
H.264/AVC Adaptation Set with AdaptationSet@id=”264” and an HEVC Adaptation
Set with AdaptationSet@id=”265” is possible by adding a Supplemental Descriptor
to the H.264/AVC Adaptation Set with @schemeIdUri set to urn:mpeg:dash:adaptation-set-switching:2016
and the @value=”265” and by adding a Supplemental Descriptor to the HEVC
Adaptation Set with @schemeIdUri set to urn:mpeg:dash:adaptation-setswitching:2016 and the @value=”264”.

Thanks

I don't believe that this will be necessary for codec switching. We will query the browser to determine what codec transitions are possible.
