OggSRT

The following is a draft!

It is at best incomplete and at worst completely broken. In any case, it is not an “official” Xiph spec or codec, so use with care.

This is an unimplented discussion draft about encapsulating srt subtitles in OggText.

Discussion is on the accessibility@xiph.org list.

SRT specification

We adhere to existing SRT specifications without modification, for player compatibility.

We base this on: http://en.wikipedia.org/wiki/Subrip#Sample_file
Accordingly, it would make sense to be lenient regarding the index number and the display position.

With considerations of web interoperability, we do NOT require support for the additional markup tags such as <b> and <font> described at: http://forum.doom9.org/showthread.php?p=470941#post470941

For details of Ogg BOS headers and granulepos etc, see OggText

It should be simple:

It doesn't need an extra header.
Each time span is mapped into a single packet.
Silvia suggests to drop the index number upon mapping into Ogg -this will make it tolerant towards packet loss.
The time span and the text will thus be the data inside the page.
