I have Googled and tried to look/search through the mailing list archives, to no avail, so I hope I didn't just overlook a previous discussion. If I have, I would appreciate a link to such a discussion.
I'm looking for a efficient and solid way to synchronise data and video/audio using something like Red5. I will have several cameras recording video of a sporting event, and I will have GPS data coming in through a processing server (that I wrote, so I have total control over messages and timing). I need to somehow embed the information into the FLV stream or make sure that all clocks and time sources are correct so that I can play the streams back later and have the data married to the video and audio correctly.
I had the idea to inject cuepoints into the FLV while it was being encoded...the cuepoint namefield could contain a reference to an external XML or database entry that could be processed by the end client, or the name field could actually contain coordinate data (I'm dealing with 6 different NMEA GPS coordinates, so if the name field length is sufficient, this may work, although not be ideal). The problem with this overall theory is that I lack an understanding of when/how the cuepoints are added to the FLV. With a brief look at the classes for doing so (if they're actually fully implemented at this point), it seemed that I might not be able to inject cuepoints into a live stream, only an FLV. My head is swimming around Red5 right now; I just installed it last week and have been playing with it, getting my feet wet.
But in order to evaluate Red5's feasibility for my solution, I need to know what is/isn't possible, and I can't afford to become an expert in Red5 in order to evaluate that.
If anyone has any ideas at all, they would be GREATLY appreciated. It seems like this would be a common problem needing to be solved in the online encoded video community, and if not already, definitely moving forward into new applications of the technology.
