I wrote such a tool which generates mp4 file-series, it is simple if you are familiar with libgpac.

You have to keep an array which maps time to file indexes, when a user wants to seek to a specific position, just convert the timestamp (e.g. 01:15:14) to file index (movie_2314_segment_519.mp4) then request it from the server.

You can also use FLVs which contain H264 and AAC if Flash Player is your only client.
