MJPEG is a popular format for webcam streams. It's probably popular because it's so simple to do and the performance is surprisingly good. Unfortunately, I found it quite difficult to scrape together enough information to implement a streamer myself. In an effort to help the next poor, frustrated soul, here's a simple method for streaming an MJPEG to a socket in Java.
public void handleConnection(Socket socket, JpegProvider jpegProvider) throws Exception { byte[] data = jpegProvider.getJpeg(); OutputStream outputStream = socket.getOutputStream(); outputStream.write(( "HTTP/1.0 200 OK\r\n" + "Server: YourServerName\r\n" + "Connection: close\r\n" + "Max-Age: 0\r\n" + "Expires: 0\r\n" + "Cache-Control: no-cache, private\r\n" + "Pragma: no-cache\r\n" + "Content-Type: multipart/x-mixed-replace; " + "boundary=--BoundaryString\r\n\r\n").getBytes()); while (true) { data = jpegProvider.getJpeg(); outputStream.write(( "--BoundaryString\r\n" + "Content-type: image/jpg\r\n". + "Content-Length: " + data.length + "\r\n\r\n").getBytes()); outputStream.write(data); outputStream.write("\r\n\r\n".getBytes()); outputStream.flush(); } }
