C608 to WebVTT translation

[Izaron]

Work in progress - translating CEA-608 subs to WebVTT

Done:

• Support of the raw old format without colors
• Added colors and fonts with segments (consecutive characters of the same font or color)

Todo:

• Replace current "webvtt" to "webvtt-raw" and "webvtt-full" to "webvtt" (???)
• Add XDS metadata what already computed by CCExtractor and written on screen; and add it in file
• True positioning as in document
• Anything else missing from the document

Aren't we missing the actual styling here? CSS or something :-)

Don't sure that there was CSS style need for CEA-608 (any hint???), by "Styling" I mean support of text color and fonts in output file in proper format. CSS styling is the post-CCExtractor work :)
Don't really think we should redefine default CSS style but if it's necessary for standart C608 look (black backgroun for example) we can just add the line in the header in the code

This what the document says: "When a WebVTT file is created from a CEA-608 or CEA-708 caption data stream using the conversion methods proposed in this document, it is suggested to use the following header for the WebVTT file, including an identification of the type of data contained: WEBVTT Style: @import(cea608.css) ## Kind: captions Language: en-US " The reason of course is that by adding such style the player can render the subtitles so they look exactly as they look on a TV (assuming everything else explained in the document is done, such as positioning, etc).
