Upload video file to s3 after recording with AMS / FMS

Can I download the published video file from AMS / FMS via http? I am currently posting a video with "_temp" added and using the ams File api to rename the file. I have a C # process watching my ams file for files without the '_temp' suffix and when it finds it, it loads it into s3. Surely there is a less complicated way to do this?

UPDATE: I recently discovered AMS C ++ plugins. Seems promising but challenging. Before investing time, is this what I want even with a plugin? Is there an open source plugin that does this already?
