Robert Simpson shows a way he found a way to get a Classic ASP script to interact with FFmpeg and create a thumbnail from the first frame of a video file without any user interaction or file manipulation.

It goes something like this:

User uploads a video file to his web server
User runs a specially prepared script
The script detects the file's type
A Wscript fires off a command to create the thumbnail and save it to a specified directory

The script looks something like this (see the attachment for more info):

<%
option explicit
dim sExecuteable
dim oShell
dim sVideoFilepath
dim sOutputFilepath
dim cmd
sExecuteable = "ffmpeg.exe"
sVideoFilepath = "sphere1.wmv"
sOutputFilepath = "sphere.png"
cmd = server.mappath(sExecuteable) & " -y -i """& _
server.mappath(sVideoFilepath) &""" -vframes 1 -an _
-vcodec png -f rawvideo -s 320x240  """&_
server.mappath(sOutputFilepath) &""""
set oShell = server.createobject("Wscript.Shell")
oShell.run cmd
set oShell = nothing
%>

Note that this works off a specially compiled version of FFmpeg, so it may not work for everyone. And for all you non-Windows users, beware! I have no clue if it'll work for you.

Download the the files and save them on your web server. Then, execute the default.asp script through your browser.

Happy Publishing!
