Free video analysis software for linux

Google Video Downloader is a Firefox extension that adds a button in the status bar. You can download the source .flv or .avi file directly in two clicks

If You:

- Would like to download files from other videohostings;
- Have DownThemAll od FlashGot;
- Would like to permanently choose preferred Google Video format.

Ook? Video Ook! is a Firefox extension that enables you to download embedded videos.
Several systems are supported such as YouTube, Google Video, Pornotube, Metacafe and many more.
Main features:
- just one click downloading (just set a target folder on the options dialog once and then click on the status icon or the button where active).
- DownThemAll! integration for better download experience
- file renaming after video title (if you want so)
- files can be stored in a specific folder
- customizable toolbar button
- hideable status icon indicates which specific pages are supported: you can also check the About dialog to get a general idea
- send your requests for sites support or other comments directly from the extension (Im working on the server side right now)
- new support can be added on the fly using the autoupdate feature

Xai is an extensible framework for prototyping and developing real time video analysis algorithms by allowing execution and composition of such algorithms in the form of data flows between algorithm blocks.
The blocks can be written in C++ by extending special interfaces, and they can be compiled to dynamically linked libraries. The algorithms can be composed using a GUI or written directly in XML.
The approach
The approach taken here was to develop a universal framework for prototyping video analysis algorithms by building them from previously prepared blocks. Each block is in fact a dynamically linked library, with well defined interface, that can be attached to a workflow of blocks and executed by the framework.
The core of the Xai is called XaiEngine and contains all functionality needed to load, run and save algorithms. Additionaly, each block is a separately developed, dynamicaly-linked C++ class, that can be loaded during run-time. Also, any number of GUIs for Xai can be developed as XaiEngine provides a universal interface for accessing the functionality. Currently Xai contains a GUI developed in Gtk and based on DiaCanvas.
Enhancements:
- Added handling of multiple blocks directories
- Added execution properties such as limiting iteration count
- Added handling of multiple algorithms through tabs
- Major refactoring of type system
- Several new macros added for easier use in blocks development

mpeg2videotools is a C library and set of tools for encoding, decoding, verification and analysis of MPEG-2 video. It supports 422 Profile and High Profile bitstreams. A PSNR tool is included for comparing uncompressed video to encoded MPEG-2 video.
The library will provide a C API and be implemented in C. Platforms supported will be popular Unices and Linux, MS Windows and MacOSX. autoconf and automake will be used to achieve portability for most platforms. Decoded bitstreams will be displayed using X11 server for Unix and native Windows API for MS Windows.
Included is an encoder and decoder application which are useful for creating compliant bitstreams and decoding and verifying MPEG-ES, MPEG-PS, MPEG-PES and MPEG-TS bitstreams.
A number of important improvements over the original SSG code have already been made:
display on TrueColor visuals (16, 24, 32 bit displays)
decoding of MPEG-TS streams
decoding of broken streams which do not start with a required start code
autoconf build
MS Windows display
a library API to enable its use in other projects (ImageMagick and the AAF SDK come to mind)
MIAMI is an MPEG-2 video codec library which aims to be a complete implementation of the ISO/IEC 13812-2:2000 standard. The priority is completeness and correctness rather than speed. Included is an encoder and a decoder for MPEG-ES,PS,PES,TS bitstreams.
Enhancements:
- changed function decs to ANSI style
- added const qualifier to suitable function args

ZoneMinder is a suite of applications intended for use in video camera security applications, including theft prevention and child or family member monitoring. The project supports capture, analysis, recording, and monitoring of video data coming from one or more video or network cameras attached to a Linux system.

It also features a user-friendly Web interface which allows viewing, archival, review, and deletion of images and movies captured by the cameras. The image analysis system is highly configurable, permitting retention of specific events, while eliminating false positives.

ZoneMinder supports both directly connected and network cameras and is built around the definition of a set of individual zones of varying sensitivity and functionality for each camera. This allows the elimination of regions which should be ignored or the definition of areas which will alarm if various thresholds are exceeded in conjunction with other zones. All management, control, and other functions are supported through the Web interface.

Analysis of Reinforced Concrete Elements will assist its user to find out capacity of various Reinforced Concrete Structural Elements.

The following professionals are the target audience:

Structural Engineers
Civil Engineers
Architect
Builders

Installation:

The software is web-based, so you need web-server (Apache) running with PHP. The installaton is very simple. If your document root is /var/www/html , then on uncompressing downloaded compressed file in this "document root", the URL for ARCE application become: http://YourWebSite/arce/

Market Analysis System (MAS) is an open-source software application that provides tools for analysis of financial markets using technical analysis.
Market Analysis System provides facilities for stock charting and futures charting, including price, volume, and a wide range of technical analysis indicators. Market Analysis System also allows automated processing of market data - applying technical analysis indicators with user-selected criteria to market data to automatically generate trading signals - and can be used as the main component of a sophisticated trading system.
Main features:
- Includes basic technical analysis indicators, such as Simple Moving Average, Exponential Moving Average, Stochastic, MACD, RSI, On Balance Volume, and Momentum.
- Includes more advanced indicators, such as Standard Deviation, Slope of EMA of Volume, Slope of MACD Signal Line, Bollinger Bands, and Parabolic SAR.
- User can create new technical analysis indicators, including complex indicators based on existing indicators.
- User can configure criteria for automated trading-signal generation.
- Creation of weekly, monthly, quarterly, and yearly data from daily data.
- Handles intraday data.
- Handles stock and futures data.
- Accepts input data from files, from a database, or from the web. (Includes a configuration for obtaining end-of-day data from yahoo.com.)
- Can be configured and run as a server that provides services for several clients at a time running on remote machines.
