Free video analysis software for linux

Net::Analysis are modules for analysing network traffic.

SYNOPSIS

Using an existing analyser:

$ perl -MNet::Analysis -e main help
$ perl -MNet::Analysis -e main TCP,v=1 dump.tcp - basic TCP info
$ perl -MNet::Analysis -e main HTTP,v=1 dump.tcp - HTTP stuff
$ perl -MNet::Analysis -e main Example2,regex=img dump.tcp - run an example

Writing your own analyser:

package MyExample;
use base qw(Net::Analysis::Listener::Base);
# Listen to events from other modules
sub tcp_monologue {
my ($self, $args) = @_;
my ($mono) = $args->{monologue};
my $t = $mono->t_elapsed()->as_number();
my $l = $mono->length();
# Emit your own event
$self->emit(name => example_event,
args => { kb_sec => ($t) ? $l/($t*1024) : N/A }
);
}
# Process your own event
sub example_event {
my ($self, $args) = @_;
printf "Bandwidth: %10.2f KB/secn", $args->{kb_sec};
}
1;

ABSTRACT

Net::Analysis is a suite of modules that parse tcpdump files, reconstruct TCP sessions from the packets, and provide a very lightweight framework for writing protocol anaylsers.
__top

I wanted a batch version of Ethereal in Perl, so I could:

- sift through parsed protocols with structured filters
- write custom reports that mixed events from multiple protocols

So here it is. Net::Analysis is a stack of protocol handlers that emit, and listen for, events.

Sequence Analysis project is a collage of coding projects which I have written over the past several years for various clients in my work as a bioinformatics consultant.

These clients have graciously allowed me to release these works into the public domain as freeware for Macintosh OS X in order to promote the platform and to encourage migration from Classic.

The upper window panel can hold several sequences, which are both editable and selectable. The tabs in the lower analysis panel try to keep up with the current sequence selection to provide immediate feedback. The selection is used in some modules as only the portion being analyzed for other modules i.e. Digest is used to determine if enzymes cut in the in or outside of the selection.

Most commonly available sequence formats have been reverse engineered. You can also access a sequences from the NCBI via its GID or UID. This currently cannot be done from behind a firewall.

Most of the analyses are simple enough that they are obvious to use, Composition, pI. Others could stand some documenation i.e. Pairwise and Primer Design. The Publish tab uses a string to control the layout. Click on the Legend button for some help.

Video server is a streaming video server which feeds a Java applet/application for display. The updates are rather slow, somewhere in the 10 frames/second range on a PIII. The server is written in Bigloo scheme and C. The client is written in Java.

To bring up the video server you have to do the following.

./vs --channel 25 --sd 12 --input 0

./vs --help
for more options. (This seems broken with the newest version of bigloo .... )

How to bring up a java client to connect to a server:
Insure that video/java is in your classpath, and invoke

java vpanel servername

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.

Video Contact Sheet *NIX or vcs for short, is a script that creates a contact sheet (preview) from videos by taking still captures distributed over the length of the video.

The output image contains useful information on the video such as codecs, file size, screen size, frame rate, and length.

Notes:

Using -i or -n with values that lead to the same number of vidcaps doesnt necessarily yield exactly the same vidcaps, youll have to play with them for best results.

Example: With a video that lasts for 22min 14secs, -n 6 will create the six vidcaps:

3:22, 6:44, 10:04, 13:28, 16:50 and 20:12, while -i 3m will create
3:00, 6:00, 9:00, 12:00, 15:00 and 18:00.

As you can see, -n distributes the vidcaps all over the video while -i N starts at N and goes in increments of it up to the end.

You can set the aspect ratio of the video with -a. It is only required for anamorphic material and discouraged for the rest.

It can take either a floating point number (like 1.33 or 1.778) or a fraction (like 4/3 or 16/9). The latter is slightly preferable.

GNOME Video Arcade is a simple xmame front-end for the GNOME Desktop Environment.

Just getting this project off the ground. Im hoping to create a simple and easy-to-use xmame front-end that is not just another mame32 clone.

This project is aimed at casual gamers like myself that just want to play classic arcade games on their desktop.

Gaim Video and Voice Support is a friendly fork of the gaim project to concentrate on video and voice support, which will eventually be backported.
