Free convert video software for linux

Requirements:

• KDE

av_convert consists of some tools for the manipulation of video files.
In more detail av_rec can capture live video and audio from any v4l framegrabber device. The program av_convert can convert between some video file formats and provide basic editing functions.
This includes extracting arbitrary parts out of different video files and combining them in one destination file. Information about videos, such as length and contained audio and video streams can be obtained by av_info.
All the functionality needed for accessing the audio and video stored in file containers is provided by a library (libVideoFile). This functionality includes frame exact positioning in the audio and video streams and decoding/encoding of the compressed data stored in the files.
The different file types and audio/video codecs are handled by individual plugin modules. These I/O backends and codecs are loaded by libVideoFile at runtime. For now, there are plugins for the most important file formats like AVI (including extension for large files), Quicktime, MPEG/DVD, YUV4MPEG stream, WAV, mp3, etc.
Enhancements:
- Compatibility with gcc 4.0 and SPARC64/Linux was improved.

3gp converter is a GUI (Kommander script) that uses ffmpeg as a backend and allows you convert the video files in 3gp format, which used at mobile phones.
You must have ffmpeg installed at you system compilled with AMR audio-codec fupport (check up ffmpeg manuals for instructions). Also you need Kommander installed(at least kommender executor).
You can set custom parameters of encoding,for video stream: resolution, bitrate, framerate, used codec (h263,mpeg4), one or two pass encoding.
For audio stream:bitrate,samplerate (AAC only), audio codec (amr_nb,AAC).
Enhancements:
- updated homepage and added some info
- sliders fix (now sliders moves when you set values manually)
- added prevew backend switch(ffplay/mplayer)
- added "exit" button
- added "stop" buttons for prevew

Convert::Bencode are functions for converting to/from bencoded strings.

SYNOPSIS

use Convert::Bencode qw(bencode bdecode);

my $string = "d4:ainti12345e3:key5:value4:type4:teste";
my $hashref = bdecode($string);

foreach my $key (keys(%{$hashref})) {
print "Key: $key, Value: ${$hashref}{$key}n";
}

my $encoded_string = bencode($hashref);
print $encoded_string."n";

This module provides two functions, bencode and bdecode, which encode and decode bencoded strings respectivly.

Convert::RACE is a conversion between Unicode and RACE.

SYNOPSIS

use Convert::RACE;

$domain = to_race($utf16str);
$utf16str = from_race($domain);

This module provides functions to convert between RACE (Row-based ASCII-Compatible Encoding) and Unicode Encodings.

RACE converts strings with internationalized characters into strings of US-ASCII that are acceptable as host name parts in current DNS host naming usage.

Convert::Wiki is a Perl module that can convert HTML/POD/txt from/to Wiki code.

SYNOPSIS

use Convert::Wiki;

my $wiki = Convert::Wiki->new();

$wiki->from_txt ( $txt );
die ("Error: " . $wiki->error()) if $wiki->error;
print $wiki->as_wiki();

$wiki->from_html ( $html );
die ("Error: " . $wiki->error()) if $wiki->error;
print $wiki->as_wiki();

# clear the object manually
$wiki->clear();
$wiki->add_txt ( $txt );
die ("Error: " . $wiki->error()) if $wiki->error;
print $wiki->as_wiki();

Convert::Wiki converts from various formats to various Wiki formats.
Input can come as HTML, POD or plain TXT (like it is written in many READMEs). The data will be converted to an internal, node based format and can then be converted to Wikicode as used by many wikis like the Wikipedia.

Convert::BER is a Perl module for ASN.1 Basic Encoding Rules.

SYNOPSIS

use Convert::BER;

$ber = new Convert::BER;

$ber->encode(
INTEGER => 1,
SEQUENCE => [
BOOLEAN => 0,
STRING => "Hello",
],
REAL => 3.7,
);

$ber->decode(
INTEGER => $i,
SEQUENCE => [
BOOLEAN => $b,
STRING => $s,
],
REAL => $r,
);

Convert::BER provides an OO interface to encoding and decoding data using the ASN.1 Basic Encoding Rules (BER), a platform independent way of encoding structured binary data together with the structure.

Convert::UUlib is a Perl interface to the uulib library (a.k.a. uudeview/uuenview).

SYNOPSIS

use Convert::UUlib :all;

# read all the files named on the commandline and decode them
# into the CURRENT directory. See below for a longer example.
LoadFile $_ for @ARGV;
for (my $i = 0; my $uu = GetFileListItem $i; $i++) {
if ($uu->state & FILE_OK) {
$uu->decode;
print $uu->filename, "n";
}
}

Read the file doc/library.pdf from the distribution for in-depth information about the C-library used in this interface, and the rest of this document and especially the non-trivial decoder program at the end.
