Projects / Palantir


Palantir is a client-server streaming system designed to transmit live video, audio, and data over a TCP/IP network. The server runs on a Linux box. The supplied Java client can display the live video stream as well as interact with hardware devices connected to the server. A native Windows client also allows full-duplex audio communications with the server.

Recent releases

  •  21 May 2007 10:21

    Release Notes: New features include text overlays, IPv6 support, and input/output audio stream decoupling. Enhancements include improved performance in audio streaming for MIPS-based routers.

      Release Notes: Support for the Logitech QuickCam Sphere/Orbit pan/tilt facilities has been improved. Support for the MotionEye camera found in some Sony laptops has been added. It is now possible to run the server in "viewer" mode, in which a X11 window displays the output from the capture source. Full support for the WL-500 router series from ASUS was added. Various improvements were made to the clients, especially the Java applet (now able to run also as an application).

      •  03 Jul 2004 21:01

        Release Notes: The first release of a native, Qt-based Linux client is now available, along with updated versions of the Windows and Java clients. The server now supports the Logitech QuickCam Sphere/Orbit pan/tilt facilities. A bug which allowed malicious clients to crash the server has been fixed. Other important features include proper handling of large frames (exceeding 640x480) and the ability to individually choose the TCP ports for the video and audio stream.

          Release Notes: A bug has been fixed which caused a malformed control string sent by a malicious client to crash the server. A workaround has been implemented for some camera drivers (W996[87]CF and CPiA) reluctant to infer the capture depth from the requested palette. Three new values for the "Visual" parameter -- Slider_X, Slider_Y, Slider_Y -- allow explicit assignment of a control to one of the sliders on the client's main window, which used to be reserved for pan, tilt, and zoom controls. The Windows client has been updated as well (2.3.1).

          •  22 Sep 2003 11:10

            Release Notes: Many improvements were made to the audio subsystem, including config options for selecting the audio input and software downsampling for devices with a fixed sample rate (such as btaudio). Another new feature is the ability to apply simple filters (at the moment, horizontal and vertical mirroring) to the captured frames. Various bugfixes were also made.

            Just what I was looking for...
            Palantir is the perfect solution for linux audio/video streaming. Using the precompiled binaries in a sytem running Mandrake 9.0, it was easy to setup and worked without error upon startup. I highly recommend this project to all who want real webcam and sound broadcasting capabilities on a linux box. Good work Santinod!
