SMIL (Synchronized Multimedia Integration Language) got updated last in 2008, does anyone know if there are better protocol to follow when it comes to synchronizing multi-media files?
回答1:
SMIL has no natural competitors, so any other solution would rely on scripting. It has support in ePub readers like Azardi as well as most phones with MMS support. The Timed Text, Media Fragments, and Media Ontology specifications address captioning, bookmarking, and indexing audio/video content respectively. No successor for SMIL has been formulated outside of the Timesheets draft, which is a resurrection of the XHTML+SMIL proposal that became HTML+TIME in IE and has a JavaScript implementation in timesheets.js.
In terms of specifications, it's part of both ePub3 and the Messaging API used in Firefox OS.
In terms of tooling, it's integrated into the Aeneas and tobi projects to sync audio and video.
In terms of software, it's integrated with JavaScript and RS-232 and subtitle codecs.
