Hi,


I have some questions regarding the article "HLS Authoring Specification for Apple Devices".


Spec: Subtitles MUST be WebVTT (according to the HLS specification) or IMSC1 in fMP4.

Questions: Is there a plan to support WebVTT under the fmp4 container type? If yes, when?

Generally speaking, Apple does not discuss future plans.


If carriage of WebVTT in fMP4 is important to you, then please create a bug and outline your reasoning for why this important.
