Support xlink:actuate=“onRequest” in DASH.js

[kyu-pluto]

It would be great if the DASH.js player can dynamically insert remote content based on internal or external events.

The xlink:actuate=“onRequest” feature should be an adequate solution. It allows the player resolves and plays back remote content when requested, e.g., triggered by an event during playback of certain content.

The new "Media Presentation Insertion" feature (still under development by MPEG-DASH standard group)seems to be a good alternative. It takes advantage of the DASH event mechanism to trigger the insertion and playback of alternative media presentation. However, its standardization and player adoption may still need a while.
