I'd like to assemble an mpeg dash playlist where I splice together multiple MPEG-Dash URLS to form a single cohesive movie.
MPEG-Dash URL 1 Start @00:10 End @00:30
MPEG-Dash URL 2 Start @01:00 End @05:00
MPEG-Dash URL 3 Play Whole File
Is this possible without breaking open all the files and creating a bunch of different periods with the individual AdaptionSet/SegmentTemplates/Timelines copied from the child streams? My worry is if I open up every file individually and one of the child streams is re-formatted everything will break.
This post mentions someone doing a dash-cast, but I'm trying to keep it in (static) MPD format since we have a player that already supports that.
Is this perhaps what SegmentURL is for?
The DASH specification supports the XML Linking Language (XLink), so you can include references to remote content such as a Period element.
Here is an example, from a DASH test file:
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
