Free frame software for linux

DBIx::Frame is a Perl module for creating and maintaining DBI frameworks.

SYNOPSIS

use DBIx::Frame;
DBIx::Frame->init(server, dbtype) || exit(0);
my $DB = DBIx::Frame->new(database, user, pass)
or die("Couldnt connect to database: ", DBI->errstr);
See below for how to actually use this object.

DBIx::Frame is an extension of the standard DBI perl module, designed around mysql, and used to create and maintain frameworks for databases. It has query logging, and a standardized interface for standard SQL statements like update and insert that doesnt require understanding SQL to any great degree.

Ideally, the user or developer shouldnt have to know too much SQL to be able to administer a database. On the other hand, it does require a certain setup that isnt necessarily easy to pick up, and isnt standard SQL - with all the problems that this entails.

Database design is discussed below.

Frameworks is stop-motion animation frame capture software primarily for Linux. It captures images from a camera and strings them together into an animation.
These still images may then be combined into a single video file using other software. Only video4linux webcams are currently supported; work is being done to add other types of digital cameras including IEEE 1394 camcorders, and USB still cameras. Frameworks is designed to be easily used alongside the GIMP Animation Package (GAP).
Frameworks began as an extension of gqcam, though it no longer shares any code with gqcam. Frameworks is free software (and therefore open source) licensed under the GNU GPL. Without gqcam being free software, Frameworks would not exist.
Main features:
- Frame averaging: The averaging together of multiple frames to reduce random noise in the captured image.
- Frame overlay or onion skinning: Overlaying previous frames ontop of the live display to assist with positioning of objects during animation.
- Continuous preview: Preview the previous few seconds of animation, ending with the live feed from the webcam to assist with object positioning.

Tk::SplitFrame is a geometry manager for scaling two subwidgets.

SYNOPSIS

use Tk;

use Tk::SplitFrame;

my $MainWindow = MainWindow->new();

my $SplitFrame = $MainWindow->SplitFrame
(
-orientation => vertical,
-trimcolor => #c7c7c7,
-background => white,
-sliderposition => 60,
-borderwidth => 2,
-sliderwidth => 7,
-relief => sunken,
-height => 100,
-width => 100,
-padbefore => 0,
-padafter => 0
);

# Values shown above are defaults.

my $LeftLabel = $SplitFrame->Label (-text => Left);

my $RightLabel = $SplitFrame->Label (-text => Right);

$SplitFrame->pack (-expand => true, -fill => both);

$SplitFrame->configure (-sliderposition => 22);

Tk::MainLoop;

A SplitFrame is a geometry manager for the two subwidgets instantiated against it. It has a sliding divider between them which, when moved, resizes them so that they each remain in contact with it.

The divider can be arranged vertically or horizontally at create time. The children our arranged in the order that they are instantiated, from left to right or from top to bottom. After instantiation, the order is fixed. The children should NOT be packed or placed, the split frame is responsible for this.

The split frame will adjust itself initially to the preferred size of the children.
It is a basic frame itself and can be packed or placed wherever needed in other frames or toplevel windows.

MPEG::Audio::Frame is a class for weeding out MPEG audio frames out of a file handle.

SYNOPSIS

use MPEG::Audio::Frame;

open FILE,"file.mp3";

while(my $frame = MPEG::Audio::Frame->read(*FILE)){
print $frame->offset(), ": ", $frame->bitrate(), "Kbps/", $frame->sample()/1000, "KHzn"; # or something.
}

A very simple, pure Perl module which allows parsing out data from mp3 files, or streams, and chunking them up into different frames. You can use this to accurately determine the length of an mp3, filter nonaudio data, or chunk up the file for streaming via datagram. Virtually anything is possible.

CGI::AppBuilder::Frame is a configuration initializer.

SYNOPSIS

use CGI::AppBuilder::Frame;

my $ab = CGI::AppBuilder::Frame- >new(
ifn, my_init.cfg, opt, vhS:a:);
my ($q, $ar, $ar_log) = $ab- >start_app($0, %ARGV);
print $ab- >disp_form($q, $ar);

This class provides methods for reading and parsing configuration files.
new (ifn = > file.cfg, opt = > hvS:)

This is a inherited method from CGI::AppBuilder. See the same method in CGI::AppBuilder for more details.

frame_set ($fr, $pr)

Input variables:

$fr - frame set definiton array reference. The $fr contains two
elements [$hr, $ar]:
$hr - a hash ref containing the frame set attributes
$ar - a array ref containing hash references defining each
frames in the frame set.
$pr - tag attribute array ref. It contains three elements:
class - CSS class name
attr - attribute string such as width=5 onChange=js_func
hr - hash ref with key and value pairs. This will be obtained
from $fr for each frame set and frame.
pretty - whether to add line breaks

Variables used or methods called:

CGI::AppBuilder::Table
html_tag - generate HTML tags
CGI::AppBuilder::Message
echo_msg - display message

How to use:

The following shows how to define the frame array ($fr):

+-+----+ The following defines the left layout:
| | T |
| +----+ [{cols= >"150,*"},[

Transcode is a suite of command line utilities for transcoding video and audio codecs, and for converting beween different container formats. Transcode can decode and encode many audio and video formats, e.g.
- MPEG-1/2
- MPEG-4(-part 3) (also DivX and XviD variants)
- Quicktime / MPEG-PS (dvd) (decode only)
- MPEG-1-layer-1/2/3 audio
- AC3 audio
Transcode has a variety of video and audio pre and post-processing filters, including (but not limited to):
- video de-interlacing
- audio resampling
- framerate conversion
- smoothing
- cutting
Transcode can import DVDs on-the-fly, or record from Video4Linux (including V4L2 video capturing) devices.
A number of modules are included to enable import of DVDs on-the-fly, Video4Linux (including V4L2 video capturing), MPEG elementary streams (ES) or program streams (VOB), MPEG1/2/4 video, Digital Video (DV), YUV4MPEG streams, Nuppel Video (NUV), quicktime (MOV), MPEG audio layer-1/2/3, WAVE, DIVX, MJPEG, and raw or compressed (pass-through) video frames.
A number of export modules for enable writing DivX ;-), DivX 4.02/5.xx, XviD, Digital Video, MPEG-1/2 or uncompressed AVI files with MPEG, AC3 (pass-through) or PCM audio. More file formats and codecs for audio/video import are supported by the MPlayer and avifile import modules (exporting with avifile is restricted to video codecs, with MPEG/PCM or AC3 (pass-through) audio provided by transcode). Limited DVD subtitle rendering is also available.
Its modular concept is intended to provide flexibility and easy user extensibility to include other video/audio codecs or file types. A set of tools is available to extract, demultiplex and decode the sources into raw video/audio streams for import, non AVI-file export modules for writing single frames (PPM) or YUV4MPEG streams, auto-probing and scanning your sources and to enable post-processing of AVI files, including header fixing, merging multiple files or splitting large AVI files to fit on a CD.
Transcode runs on UN*X like systems like Linux, BSD, and MacOSX.
Transcode loads shared library modules that are responsible for feeding it with raw streams and encoding the frames:
The Import Modules for audio/video decoding are loaded with dlopen system call and are responsible for starting the video and audio streams (directly or via the popen system call) and have a single function interface to the main program. The import is handled by a thread that buffers the video/audio frames.
The main program transcode currently performs a number of simple video/audio frame manipulations (in this order) or allows simple pass-through of raw frame data:
Video:
- cut out arbitray frame region for processing
- de-interlace video frame
- fast enlarging of video width/height by a multiple of 32 rows/column up to 1024x768
- fast reduction of video width/height by a multiple of 32 rows/column
- high-quality resizing with filter
- cut out arbitray frame region for encoding
- rescale (downsample) video width/height by a power of 2
- flip video frame upside down
- mirror image of video frame
- swap R and B bytes in video frame
- transform to b/w video frame
- apply gamma correction
- anti-alias video frame
Audio:
- change the volume of the audio stream
- resample audio stream
- swap byte order in audio stream
- sync video with audio frames (V=0|A=N, V=1|A=N+1,...)
- Filter Plugins:
- Additional effects are available via external filter plugins loaded with option "-J".
The Export Modules for audio/video encoding are loaded via the dlopen system call and the encoder loop is started for the selected frames. In most cases audio and video are handled by the same module.
Enhancements:
- This release includes only critical hotfixes.
- The main highlight is compatibilty with newer releases of ffmpeg libraries.
- Some filters have been updated.

SOAP::XML::Client is a simple frame work for talking with web services.

This package is the base class for talking with web services, there are specific modules to use depending on the type of service you are calling, e.g. SOAP::XML::Client::DotNet or SOAP::XML::Client::Generic

This package helps in talking with web services, it just needs a bit of XML thrown at it and you get some XML back. Its designed to be REALLY simple to use.

LANtern is a frame and packet analyzer for Linux. Its written in C (without pcap) and released under the MIT license.

LANtern currently supports ethernet frames, ARP, MPLS, RARP, IPv4 (AH, ESP, GRE, ICMP, IGMP, TCP, IPComp, UDP, UDP-Lite, and IP-in-IP encapsulation)

I hope to soon write/release a BSD version.

Feel free to make changes to fit your needs. This isnt released under the GPL so youre not "required" to submit modifications, but if you want to send me some enhancements or new features, please do.
