Free video 0.3 software for linux

VDOWall is an application which enabled you to create a realtime streaming video out of different sources.

These sources can be controlled seperately and are then combined into one single stream, which can then be displayed with a projection device, such as a beamer. This displaying can be used to display cool looking graphics and videos during a party, display information during congresses or other events or even to create prerecorded videos for different uses.

VDOWall is written in C++ using both OpenGL and the Qt toolkit, made by Trolltech. It started out as a project to learn myself programming with C++ and a bit OpenGL, but as a few people started to show interest, Ive made it a public project. There is no real goal in this, besides the goal to learn to program, but well see what road it follows.

The design is fairly simple: its an application which acts as a framework for certain plugins. These plugins are used as sources which are compiled into one single stream, the video output. This output can then be streamed to the projection device or saved as a compiled video file onto a storage medium.

These plugins which act as sources can differ from loading images, videos or even create realtime OpenGL visuals. Each plugin has its own controls which are displayed on the application when clicked upon.

The design enables people to create plugins from scratch fairly easy, and as they are loaded during startup as shared libraries, one just needs to put the plugin into a directory, restart the application and the plugin should work.

SDL::Video is a SDL perl extension.

SYNOPSIS

$video = new SDL::Video ( -name => pr0n.mpg );

SDL::Video adds support for MPEG video to your SDL Perl application. Videos are objects bound to surfaces, whose playback is controled through the objects interface.

METHODS

SDL::Video::error() returns any error messages associated with playback
SDL::Video::audio(bool) enables or disables audio playback, (on by default)
SDL::Video::video(bool) enables or disable video playback, (on by default)
SDL::Video::loop(bool) enables or disable playback looping (off by default)
SDL::Video::volume(int) set the volume as per the mixer volume
SDL::Video:display(surface) binds the clip to a display surface
SDL::Video::scale([x,y]|[surface]|int) scales the clip by either x,y factors, scales to the image dimensions, or a single scalar.
SDL::Video::play() plays the video clip, call SDL::Video::display() before playing
SDL::Video::pause() pauses video playback
SDL::Video::stop() stops video playback
SDL::Video::rewind() resets the clip to the beginning
SDL::Video::seek(offset) seeks to a particular byte offset
SDL::Video::skip(time) skips to a particular time
SDL::Video::region(rect) takes a SDL::Rect and defines the display area
SDL::Video::frame(int) renders a specific frame to the screen
SDL::Video::info() returns a new SDL::MPEG object reflecting the current status
SDL::Video::status() returns either SMPEG_PLAYING or SMPEG_STOPPED or SMPEG_ERROR

Video::Xine is a Perl interface to libxine.

SYNOPSIS

use Video::Xine;

# Create and initialize the Xine object
my $xine = Video::Xine->new(
config_file => "$ENV{HOME}/.xine/config",
);

# Load a video driver
my $video_driver = Video::Xine::Driver::Video->new($xine,"auto",1,$x11_visual);

# Create a new stream (put your video driver under $DRIVER)
my $stream = $xine->stream_new(undef,$DRIVER);

# Open a file on the stream
$stream->open(file://my/movie/file.avi)
or die "Couldnt open stream: ", $stream->get_error();

# Get the current position (0 .. 65535), position in time, and length
# of stream in milliseconds
my ($pos, $pos_time, $length_time) = $stream->get_pos_length();

# Start the stream playing
$stream->play()
or die "Couldnt play stream: ", $xine->get_error();

# Play the stream to the end
while ( $stream->get_status() == XINE_STATUS_PLAY ) {
sleep(1);
}

A perl interface to Xine, the Linux movie player. More properly, an interface to libxine, the development library. Requires installation of libxine.

Xine by itself does not provide a user interface, and neither does this interface. Instead, you must set up the window using your own windowing code, and pass the window information to Xine.

vdr_remote is a graphical remote control for the video disk recorder vdr. vdr_remote connects over a TCP/IP network and gives you a complete remote control.

Video::Info::FOO is a Perl module for video information.

Video::Info::FOO - what is it useful for? an example list:

-video codec
-audio codec
-frame height
-frame width
-frame count
and more!

SYNOPSIS

use Video::Info::FOO;

my $video;

$video->vcodec; #video codec
$video->acodec; #audio codec
...

What does the module do? What are its limitations? Is it built on top of other code? If so, what are the details and where can I get it?

Video::Info::RIFF is a Perl module that can probe DivX and AVI files for attributes like:

-video codec
-audio codec
-frame height
-frame width
-frame count
and more!

SYNOPSIS

use Video::Info::RIFF;

my $video;

$video = Video::Info::RIFF->new(-file=>$filename); #like this
$video = Video::Info::RIFF->new(-file=>$filename,-headersize=>$headersize); #or this

$video->vcodec; #video codec
$video->acodec; #audio codec
...

RIFF stands for Resource Interchange File Format, in case you were wondering. The morbidly curious can find out more below in REFERENCES.

Video::Info::MPEG is a basic MPEG bitstream attribute parser.

SYNOPSIS

use strict;
use Video::Info::MPEG;

my $video = Video::Info::MPEG->new( -file => $filename );
$video->probe();

print $file->type; ## MPEG

## Audio information
print $file->acodec; ## MPEG Layer 1/2
print $file->acodecraw; ## 80
print $file->achans; ## 1
print $file->arate; ## 128000 (bits/sec)
print $file->astreams ## 1

## Video information
printf "%0.2f", $file->fps ## 29.97
print $file->height ## 240
print $file->width ## 352
print $file->vstreams ## 1
print $file->vcodec ## MPEG1
print $file->vframes ## 529
print $file->vrate ## 1000000 (bits/sec)

The Moving Picture Experts Group (MPEG) is a working group in charge of the development of standards for coded representation of digital audio and video.
MPEG audio and video clips are ubiquitous but using Perl to programmatically collect information about these bitstreams has to date been a kludge at best.

This module parses the raw bitstreams and extracts information from the packet headers. It supports Audio, Video, and System (multiplexed audio and video) packets so it can be used on nearly every MPEG you encounter.
