I have developed an application where the visitors of site come and upload movie clips of MPG, MPEG, MOV, RAR format get uploaded. I would like to create a functionality so that whenever a movie is uploaded, automatically a thumbnail of that movie should be created. the thumbnail should be extracted from any frame from within that particular movie clip. the best example is youtube movie uploads.
I am still unable to find any solution and did lot of search about it on internet. Please let me know the technique if any one has done this before or any link to a resource where I can search and get an idea how this is done.
