Ross, The video streams we are dealing with for our project mainly involve Unmanned Aerial Vehicle (UAV) video footage which comes to us as a video stream over the network. Due to the nature of the video, we need to be able to view it as soon as possible. We have an option to view it live from the source (non-rtsp approach with no trick play features) and we also want to be able to view the video footage in near-real time via rtsp. The benefit of the rtsp approach is that each user can have a unique rtsp session of the video with the intent of near-real time trick play. If an analyst sees something of interest in the video, they need to ability to rewind (or at least seek backwards) a few seconds before the video segment of interest to verify the footage. The ability to re-verify a video segment in the recent past, while watching the near-real time video, is why we would like to have this Live555 Indexing feature.
Also, these videos will remain archived and available via rtsp for future analysis, so we will be using the rtsp and trick play options after the video is completely received. We are just hoping that we could use a live indexing rtsp feature for the near-real time analysis use case instead of creating a custom caching of the video until the video is fully received and indexed. As the video stream we are receiving may be very long (may be up to or more than an hour is some cases), we cannot realistically index the file as we are receiving it without the requested feature.

What specific 'trick play' operations do you want the server to be able to perform on the Transport Stream file while it is still growing? (I'm trying to understand whether/when this actually makes sense.) Is it possible to create the tsx file as I am recording and continue indexing as new data if received (so having the indexer block and wait for new data) while also having that partially complete tsx file be used with the Live555MediaServer for trick play? I may well end up adding this feature - but first, I'd need to get a feel for how much it makes sense (thus my question above). Ross Finlayson Live Networks, Inc. http://www.live555.com/
