JavaTV Program source code
Need to play Windows Media files and streams, mpeg4 video or DVDs in java? Access WDM capture devices? Control a firewire DVCam? Then maybe this can help you. dsj is an ongoing project to provide a java wrapper around Microsoft s DirectShow API. It offers a set of high level classes that give java easy access to functionality widely missed by java programmers and also lets you dive deeper into the interiors of Windows core api for 2D media. On the java side dsj tries to keep things open as possible - you may use it standalone or let it feed data into JMF or other APIs.
這是一個(gè)Linux下的USB攝像頭捕捉程序，是一個(gè)調(diào)用V4L2（Video for Linux 2）非常好的例子。英文介紹為：This is a driver for the USB video bridge USBVision from Zoran/Nogatech, a USB-only cable used in many "webcam" devices. It supports streaming and capture of color or monochrome video via the Video4Linux API. Most V4L apps are compatible with it, but a few video-conferencing programs do not work yet.
Linux driver for FujiFilm FinePix digital cameras in PC-CAM (i.e. webcam) mode
driver/
Contains the driver sources.
Compile with "make".
Then as root, install with "make install".
Type "modprobe finepix" to load the module.
userspace/
Type "make" to compile.
fpix: test program, independant of the driver. Uses libusb to
directly access the camera and capture a frame, saved
under frame.jpg. Will not work if the driver is loaded.
fpixtest: test program. Uses V4L2 to capture an image.
fpix-stress-v4l2: never ending (in theory) stress test derived from fpixtest.
This archive includes the Delphi component TScreencapture (D3,D4,D5)
that implements an interface to the capture DLL of our screen capture
tool "T.N.T".
Magenta Systems Internet Packet Monitoring Components are a set of Delphi components designed to capture and monitor internet packets using either raw sockets or the WinPcap device driver. Hardware permitting, ethernet packets may be captured and interpreted, and statistics maintained about the traffic. Uses of packet monitoring include totalling internet traffic by IP address and service, monitoring external or internal IP addresses and services accessed, network diagnostics, and many other applications. The component includes two demonstration applications, one that displays raw packets, the other that totals internet traffic. The components include various filters to reduce the number of packets that need to be processed, by allowing specific IP addresses to be ignored, LAN mask to ignore local traffic, and ignore non-IP traffic such as ARP.
The Packet Debugger, pdb is a program which allows people to work with
packet streams as if they were working with a source code debugger. Users
can list, inspect, modify, and retransmit any packet from captured files as
well as work with live packet capture.
Capturing low-level network data can be hard in Java, but it s certainly not impossible
If you want to capture network packets in your Java program, you ll need a little help because no parts of the core Java APIAPI give access to low-level network
Network Tools
In this exercise, you will make use of common network tools. For each part below, capture the appropriate program output and include it with your answers to the questions.
