Hi Daraku,

the answer to question 3) is that only Annodex files (see http://www.annodex.net/) have a text track in them in which subtitles can be stored. So, if you use anxrip on a ogg+skeleton+theora+vorbis+CMML file (which is an Annodex video), you will be able to get the text out using anxrip or if you are searching for a library, using libannodex.

A subtitle editor would actually be used to create the subtitles and store them with the video in such files, but I guess also to read such files and edit them.

Hi All!

I have some troubles with OGG and GStreamer:

1) When I parsing ogg file with ogmdemux element, I recieve (in 
"pad-added" signal callback) video pad as "application/x-ogm-video", but 
not as "video/something". And that why I can't link It to the oggmux 
element and  write new OGG file :(

2) I'am using "playbin" to play media file, but It have some ugly 
seeking. Where I can't find some info on how to make good seeking (event 
by frames)?

3) How to extract subtitles from OGG files? I need It for my program 


P.S.  My program written in Python.
