Any way to link to play a segment of a larger streaming file?

Does anyone know how to upload one large video file (~20 minutes) and then create links that would just play it in smaller segments - like from 2:25 to 2:50?
Is there some sort of software/streaming site that can do this - or do I have to break up the large file into smaller chunks?
Just trying to avoid hours of tedious editing...
Thanks for any thoughts!!!
