The ability to split a recording down into a specific section and have it be it's own standalone demo.
For example, I have DEMO_A. I wish to create DEMO_A1 which is only 3:12 to 9:15 of DEMO_A. I also wish to create DEMO_A2 which is only 11:15 to 21:09 of DEMO_A.
I am working on a doom recordings database similar to what challenge-tv provided in the past. The goal is to make this as user friendly as possible, without having to teach people how to use the recording playback features of every single port just to get what they're looking for.
In the past, and even today, demos may contain multiple games. An example would be myself vs Hatred from ZDDL in 2008. It would have 5 games on a single recording, game 1 would Map1, game 2 is D5M1, game 3 is Judas, etc. From a database point of view, for full search capabilities, it'd be ideal to have a single database demo/record be on a single map. Perhaps a user is only interested in all D5M1 games by Hatred. Same for usability, not having to teach someone to fast forward and where to fast forward to in order to find their game.
I imagine the tool would need to do the following:
1. Process the demo up until the starting timestamp is reached, keeping track of the game state.
2. Create a new demo file, setting the initial game state information from step 1.
3. Copy all of the demo information (instructions) into the new demo file from the starting timestamp up until the ending timestamp is reached.
4. Finalize the new demo file with the appropriate end demo information as required.
This assumes that the demo file can provide all game state information required to start at any point in time. It may be the case that the game state information can only be determined when a map is initially loaded. If that is the case, then I'm still sure the demo can be cut down, but only to when the map started, not to any given timestamp.
Perhaps in that case, a person can be presented with all of the timestamps of a map being loaded and then has to select the starting point from that list. The demo would then be split to just that given start until an end screen is displayed or something.
