Show "Screen Shot" of uploaded video run time with Flash or .net?

[ShawnMolloy]

Hello,

Looking for some advice.

I'm trying to replicate something they do on YouTube and GoogleVideo.

http://www.youtube.com/browse

I want to be able to accomplish the following:

- A user uploads a video
- The server somehow pulls one frame of the video
- Server saves that frame as a bitmap of some kind

I can think of some possible ways of doing it, but nothing I'm really willing to build myself. Maybe there is a good .net graphics api that allows frame access to vids? Maybe a media server app can do it? Maybe flash can? I dunno any one have any clues??

Ask the guys at youtube, perhaps? They may have a page on their technology choices... or you may find they mentioned something in the media.

Cheers,
Jeff

Hey Jeff,

I never found a really easy pluggable way of doing it. Some people said they have found some methods of doing it with GDI+, which entails building a com object in c++ or some language and having it pass your web app the screen shots (which is how youtube does it), but that kind of stuff is outside the scope of our project. I was hoping flash could do accomplish this but apparently its limited, or possibly possible with flash communitcation server (com server is like a $4,000 program...)

But anyway thats for the follow up; I'll let you know if I come across something else - im still lookin.

Well, the easy way would be:

1. Upload the vid to the server
2. Run the vid against a program that captures screenshots (most save as .jpg by default)
3. Save the screenshot in a folder (best way to map the screenshot to the vid is to name the screenshot the same thing as the vid)
4. Display on the screen

Do a google search on 'screen captures' or something similar for the program that makes screenshots.
