Description Glenn Maynard 2012-08-10 18:35:49 UTC
For non-browser use, WebVTT files should be able to specify an external stylesheet directly:

Stylesheet: captions.css

WebVTT files embedded within WebM would use this to refer to stylesheets also embedded in the file.

This is related to #15023, but doesn't require duplicating the stylesheet in every track.

For WebVTT files embedded within MKV/WebM, this should find an attachment with the given name.  This is how font embedding works for MKV.  (@font-face in an inline stylesheet, and in stylesheets loaded from WebM attachments, should do this too.)

Would need to say what the base URL is. I think using the WebVTT file's URL is probably best.

I've upped the priority & importance on this bug, even though I know it doesn't really mean anything. We're about to implement the proposed spec in this bug as the WebVTT spec provides no solution for this right now.
Comment 3 Ian 'Hixie' Hickson 2012-08-30 17:02:31 UTC
This is redundant with bug 15023 since once you have inline styles you can just use @import.

@import (captions.css);
