VISCA Camera Control Library is a library for controlling a VISCA(tm) compliant camera through the RS232 port of your PC. VISCA, on its side, is a protocol developed by Sony so that a lot of machine vision cameras from Sony are compliant with VISCA.

Typical cameras include the FCB-IX47 family of camera block for OEMs. Note that other devices, such as VCRs, can be controlled. Drop me a line f you know other functions that you would like to be implemented and for which you have the opcodes.

libVISCA has been tested only with an FCB-IX47P. This does not mean that its the only camera compatible, but some others might require addition/changes. In the current version, libVISCA has interface functions for every command/inquiry of the specifications. This includes zoom, focus, digital effects, white balance, and much more.

Every function composes an RS232 message, up to 12 bytes long. The message is then sent to a function that will actually send the 12 bytes after appending a header and footer. The function also waits for answers from the camera, such as ACK and completion messages. If its an inquiry, the reply is stored in the input buffer of the interface structure.

XMMSd web control plug-in allows XMMS to be controlled with a Web browser. It makes it easier for languages like PHP to remotely control XMMS.

Computer History Graphing Project is a computer family tree.

The Computer History Graphing Project is an attempt to graph every computer standard, every piece of hardware, every OS, and every computer language in one big family tree.

XMMS-Control provides a Web-based control for XMMS.
XMMS-Control is a web-based interface for the XMMS (X MultiMedia System). XMMS is an MP3 player for Linux based systems (it also plays other media formats).
XMMS-Control is a graphical interface for the command-line utility XMMS-Shell.
Using XMMS-Control, you can control the music playng from an XMMS equipped machine from any PC on the network, including wireless laptops/PDAs!!!
Imagine being out in the pool and being able to control the music with an 802.11b based PocketPC using a browser! You can do it with XMMS-Control!
XMMS-Control has an interface for standard PCs (desktops/laptops), as well as a mobile/PDA formatted interface, for smaller screens!!!
In addition, XMMS-Control can itself be controlled via other programs (i.e., custom interfaces) using the XMMS-Control API/Hooks program! You can tie XMMS-Control into a larger system via this method.
Lets say youre creating a system for whole-house automation, and you wish to use ONE consistent interface. Well, with the XMMS-Control API/Hooks, you can!!!
Enhancements:
- Some major bugfixes... should work MUCH BETTER on most platforms that had problems before. If you had problems getting XMMS-Control installed and running, please try this new version! Please read the new installation entries in the manual!!!
- More detailed installation instructions for getting XMMS-Shell up and running (including V0.99) in the README & manual.
- Directories are now SORTED alphabetically on the file chooser screen (previously was unsorted).
- Should handle MP3 lists with file names and ID3 tags containing commas much better now (previously when a comma was encountered, the list was off by one, the name would get split, and the second half would go to the next line).
