Why not use Ogg Kate and a srt file to include commands instead of
subtitles - then after decoding with libkate (or from gstreamer), you
can simply execute your commands with some other program.

srt could also be used as the external file type, but then you have to
do the synchronisation between the media file and the srt file
yourself.

(I think that's what oggk also means, but I wasn't quite sure, so
thought it worth clarifying).
