Theora (or more accurately, the Ogg container) does not have a standard
system for coding these sorts of timed events. You can easily create one
My recommendation is to use a separate file containing a labeled list of
timestamps within the video. If it is important that only one file be
used, you can encapsulate the contents of that file inside the Ogg file in
a Skeleton "message header". There are utilities and libraries available
for easily reading and writing these message headers.
