When looking at what in-line time-aligned text codecs to support in Ogg, one may also want to look at what existing media players (outside the Web) are able to decode. There is actually support for decoding of Kate and CMML Ogg tracks in typical open source media players like mplayer or vlc. However, not much content has been produced other than test content that uses these formats to provide subtitles, captions, or other time-aligned text. The most uptake that either format has achieved is as an export format for Metavid: http://www.metavid.org/. Mostly, the solutions for using subtitles with Ogg has been to use srt files and have the media players synchronise them. | When looking at what in-line time-aligned text codecs to support in Ogg, one may also want to look at what existing media players (outside the Web) are able to decode.

'''Recommendation 6:''' | '''Recommendation 6:''' Implement support for srt as a simple format in Ogg, e.g. full OggSRT support. This includes an encoding and decoding library for OggText codecs, implementation of the mapping of srt into OggText, creation of a few srt and OggSRT example files, as well as mapping of srt to HTML, and display in Firefox. Further, there should be transcoding tools for other simple formats to srt. Details of some of these steps need to be worked out. | ||
'''Recommendation 7:''' A decision on supporting a comprehensive format in Ogg is non-obivous, even though we currently tend towards TDHT. Further discussion about TDHT, Kate and DFXP as rich formats for in-line in Ogg and for Firefox are necessary. Possibly the best start is to create example files for all of the different formats and categories to be able to compare these rich formats and get closer to a sensible decision. | '''Recommendation 7:''' A decision on supporting a comprehensive format in Ogg is non-obivous, even though we currently tend towards TDHT.
