A client has a live video stream and a Silverlight player, we would like to add closed captions to the player. However, due to lag we need a way of synchronising the video and the captions.
TimelineMarkers (http://msdn.microsoft.com/en-us/library/system.windows.media.timelinemarker(VS.95).aspx) seems like the way to archive this, however, I can't find an example of how to insert them into a live stream.
Im looking for something like this http://www.adobe.com/devnet/flashmediaserver/articles/metadata_video_streaming_print.html but for Silverlight.
