Playing an MPEG movie, starting and ending in specific places?

Question

I've compiled an MTS video into MP4 format using FFMPEG. The video is 2 minutes long.

I want to be able to play the video back but start at 0:15 seconds and end at 0:45 seconds. Effectively I want the playback software to only show 30 seconds of playback available. The software must be a Flash-based application for integration into HTML.

Does anyone know any software that'll do this? Thanks in advance.

I know this doesn't answer your question, but wouldn't it be better to crop the video to just the section you need? — Aaron Silverman, Aug 26 '10 at 18:41
Do you mean record the 30 seconds and save it as a separate clip? — Reado, Aug 26 '10 at 18:44
I know what you mean. I'm using a server-side solution for the video compilation, FFMPEG, and worked out last night how to crop the video into a video clip. Works rather well too. — Reado, Aug 27 '10 at 20:19

Thanks, just thought, how would you stop the player downloading and buffering the entire video if all you want to do is view 30 seconds of it? YouTube seem to do this - if you're half-way through a video and you switch to another SD/HD mode, it continues half-way instead of going back to the beginning. Or is that because they use a video streaming server? — Reado, Aug 27 '10 at 20:23
oh, its because they are stream via RTMP protocol from server as FMS or Red5, and there you can control buffering of **live** video channel. — Eugene, Aug 28 '10 at 03:05

I found some server-side software that'll do the trick:

http://h264.code-shop.com/

Available in different flavours depending what web server you're running. Allows the video to be streamed. Also lets you decice where to start and end.
