We have an application that streams audio/video with synchronized events. The Wowza documentation for injecting cuepoints was very helpful. The issue we're experiencing now is that when a user begins playing our audio/video, we want to know what was the most recent previous synchronized event, such that we can show the correct image, advertisement, etc. Our goal would be to create a mapping between chunknames and stream times in our application. I'm unable to find an interface to implement that provides for listening to the packetizer and sending a message when a new chunk starts. Otherwise, is there a way to name the chunks such that their name reflects the overall stream time when they started? I see that through a configuration change the chunks can be named with the stream time. Is something like this possible without recording the data?
