I've got video capture and ftp connection working, but the upload fails for some reason. I don't know how to debug why... not sure if it's that my local dir isn't specified right or if there's some other thing.
Here's the code. I'm able to connect to my site and get the dir listing, so I know THAT much works.

// Populate these variables with the necessary info.
String host = "website.com";
String username = "mrguy";
String password = "888888888";
String remotePath = "";

String localPath = "C:/Users/Duck/Documents/Processing/FTPthinger";

int frameCount=1;
void setup ()
{
 size(320,240);
  cam = new Capture(this, 320,240);
  frameRate(1);
}

void draw()
{
//  every so often, upload a pic  
 if (cam.available() == true)
 {
   cam.read();
   //image(cam, 0,0);
   // The following does the same, and is faster when just drawing the image
   // without any additional resizing, transformations, or tint.
   set(0,0, cam);  
 }
 println ("Frames left until upload: " + frameCount);
 if(frameCount-- < 1)
 {
   frameCount=10;
   upload();
   saveFrame("capture.jpg");
 }
}

void upload()
{
  try {
   ftp = new FTPClient();
   // set up client
   ftp.setRemoteHost(host);
   FTPMessageCollector listener = new FTPMessageCollector();
   ftp.setMessageListener(listener);

   // connect
   println ("Connecting");
   ftp.connect();

   // login
   println ("Logging in");
   ftp.login(username, password);

   // set up passive ASCII transfers
   println ("Setting up passive, ASCII transfers");
   ftp.setConnectMode(FTPConnectMode.PASV);
   ftp.setType(FTPTransferType.ASCII);

   // get directory and print it to console
   println ("Directory before put:");

   String[] files = ftp.dir(".", true);
   for (int i = 0; i < files.length; i++)
    println (files[i]);

   // copy file to server
   println ("Putting file");
   ftp.setType(FTPTransferType.BINARY);
   ftp.put("capture.jpg", "capture.jpg");

   // get directory and print it to console
   println ("Directory after put");

   files = ftp.dir(".", true);
   for (int i = 0; i < files.length; i++)
    println (files[i]);

   // Shut down client
   println ("Quitting client");
   ftp.quit();

   String messages = listener.getLog();
   println ("Listener log:");

   println(messages);
   println ("upload complete");

 } catch (Exception e) {

   println ("upload failed");

 }
