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.

The following describes the SRT format: http://forum.doom9.org/showthread.php?p=470941#post470941

According to: http://en.wikipedia.org/wiki/Subrip#Sample_file it would make sense to be lenient regarding the index number and the display position.

Encapsulation

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.
