Converseen is an open source project written in C++ with the powerful Qt4 libraries. Thanks to the Magick++ image libraries it supports more than 100 image formats. Converseen can convert and resize an unlimited number of images to any of the most popular formats: DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF.

With Converseen you can save your time because it allows you to process more than one image with one mouse click!

Converseen is very simple: it features a very simple user interface without strange options.

With converseen you can:
* Carry out a single or a multiple conversion.
* Resize one or multiple images.
* Compress images for your web pages.

Flash Video (flv) Metadata / Cue Point Injector and Cutting Tool - Flvtool2

FLVTool2 calculates various meta data and inserts a onMetaData tag in the video. It cuts FLV files and adds cue Points (onCuePoint). A debug command shows the inside of a FLV file and the print command gives meta data information in XML or YAML format.

What is CuePoint:
A cue point is a point at which the video player dispatches a cuePoint event while a video file plays. You can add cue points to an FLV file at times that you want an action to occur for another element on the web page. Cue points allow you to receive control in your ActionScript code to synchronize points in your FLV file with other actions on the web page.

FLVTool2 Features
* Batch processing
* Directory recursion
* Command chaining
* FLV files cutting
* onCuePoint tag insertation via XML file
* Custom onMetaData key-value pairs
* Meta data printout in XML or YAML
* Simulation mode
* Runs on Windows, Linux and Mac OSX
* Ideal for serverside automatic meta data injection

Metadata Injector for FLV Video Files - Flvmeta

The information that composes an FLV file is the data, and the metadata is information about that video. The length of the video (duration), the number of frames per second that the video displays (frame rate), and the number of kilobytes of data transferred per second when the video plays (video and audio data rates, where applicable) are all examples of video metadata. Additionally, the codec used to encode the video is also available.

Importance of FLV Metadata
Most FLV players read the metadata first to know the duration of the video file. After that it initializes or synchronizes the video file with its timeline or seekbar. If there is no metadata the seekbar will not progress with the video. Secondly, for more intelligent FLV players that serve the video or rather buffer the video dynamically, depending on the user’s internet speed, the FLV players read the FLV video bitrate from the FLV metadata and then sets the buffer accordingly.

Shares Files Using HTTP Protocol - Qweborf

Transferring files from one computer to another on a network isn't always a straightforward task. Equipping networks with a file server or FTP server or common web server is one way to simplify the process of exchanging files, but if you need a simpler yet efficient method, try Qweborf, Qweborf is a small GUI based application that facilitates transfer of files across networks and only requires the recipient of the files have a Web browser.

Qweborf provides an easy to use interface to share local files using the HTTP protocol weborf as web-server. It can enable writing on the server, webdav and authentication.

Qweborf Installation:
Open the terminal and type following command to install Qweborf:

sudo apt-get install qweborf

Multiple GNOME Terminals in one Window - Terminator

Terminator, multiple terminals in one window. The goal of this project is to produce a useful tool for arranging terminals. It is inspired by programs such as gnome-multi-term, quadkonsole, etc. in that the main focus is arranging terminals in grids (tabs is the most common default method, which Terminator also supports).

Terminator gives the possibility of having multiples terminal within the same window. As such, it makes it easier to handle multiple terminal sessions as for instance, working in one console and monitoring another one without constantly switching from a window to another.

Terminator Features:
* Arrange terminals in a grid
* Tabs
* Drag and drop re-ordering of terminals
* Lots of keyboard shortcuts
* Save multiple layouts and profiles via GUI preferences editor
* Simultaneous typing to arbitrary groups of terminals
