Free video info 0.993 software for linux

Video::Info can retrieve video properties such as: height width codec fps.

SYNOPSIS

use Video::Info;

my $info = Video::Info->new(-file=>my.mpg);

$info->fps();
$info->aspect();
## ... see methods below

Video::Info is a factory class for working with video files. When you create a new Video::Info object (see methods), something like this will happen: 1) open file, determine type. See Video::Info::Magic. 2) attempt to create object of appropriate class (ie, MPEG::Info for MPEG files, RIFF::Info for AVI files). 3) Probe the file for various attributes 4) return the created object, or a Video::Info object if the appropriate class is unavailable.

Currently, Video::Info can create objects for the following filetypes:

Module Filetype
-------------------------------------------------
Video::Info::ASF ASF
MP3::Info MPEG Layer 2, MPEG Layer 3
Video::Info::MPEG MPEG1, MPEG2, MPEG 2.5
Video::Info::RIFF AVI, DivX
Video::Info::Quicktime MOV, MOOV, MDAT, QT
And support is planned for:
Module Filetype
-------------------------------------------------
Video::Info::Real RealNetworks formats

Video::Info::ASF is a Perl module for ASF files for attributes like:

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

SYNOPSIS

use Video::Info::ASF;

my $video;

$video = Video::Info::ASF->new(-file=>$filename); #like this

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

ASF stands for Advanced Systems Format, in case you were wondering. It used to stand for Active Streaming Format, but Microsoft decided to change it. This type of file is primarily used to store audio & video data for local or streaming playback. It can also be embedded with commands (to launch a web browser, for instance), for an "immersive" experience. ASF is similar in structure to RIFF. (See RIFF::Info). 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.

Video::Info is a suite of modules to probe video files for various attributes.

Previous versions of Video::Info depended on external modules, such as RIFF::Info and ASF::Info. This is no longer the case, you dont need to install them. All the functionality is now included with the Video::Info distribution.

INSTALLATION:

To install this module type the following:

perl Makefile.PL
make
make test (optional)
make install

SYNOPSIS

my $mi = Movie::Info->new || die "Couldnt find an mplayer to usen";

foreach my $file (@ARGV) {
my %info = $mi->info($file) || warn "Couldnt read info from $filen" && next;
print "$file (WxH) - $info{width}x$info{height}n";

}

Movie::Info is a thin layer around MPlayers --identify command line flag. As such it can only give you as much information as Mplayer is able to give you which is down to the quality and number of codecs you have installed.
MPlayer is available from http://www.mplayerhq.hu/

This module is largely based on the midentify script shipped with MPlayer.

METHODS

new [path to mplayer]

Returns a new Movie::Info instance or undef if it cant find an mplayer binary.
To find a binary it looks in three places - firstly if youve passed in a path to look at it checks there, secondly at the environment variable $MOVIE_INFO_MPLAYER_PATH and then finally it searches your $PATH like the standard which command in Unix.

info < filename >

Returns a hash representing all the meta data we can garner about file.
Returns undef if it cant read the file.

Video::Info::MPEG::Constants is a suite of modules to probe video files for various attributes.

Previous versions of Video::Info depended on external modules, such as RIFF::Info and ASF::Info. This is no longer the case, you dont need to install them. All the functionality is now included with the Video::Info distribution.

To contribute, use Video::Info::FOO as a template to write a module, and email it to the Allen Day. Also see t/FOO.t as an example test script to verify the sanity of your code.

Installation:

To install this module type the following:

perl Makefile.PL
make
make test (optional)
make install

FLV::Info is an extract metadata from Flash Video files.

SYNOPSIS

use FLV::Info;
my $reader = FLV::Info->new();
$reader->parse(video.flv);
my %info = $reader->get_info();
print "$info{video_count} video framesn";
print $reader->report();

This module reads Macromedia FLV files and reports metadata about those files.

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
