Free audio video software for linux

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

This application is particularly useful for owners of digital DV video cameras and other people who use the Sony DV video format for high quality video production.

DV Assembler allows you to append multiple Sony DV files with nice looking transition effects for both audio and video. Multiple transition effects are supported, like cross-fade, zoom, blur and a flash effect.

I created DV Assembler because there are no user friendly video editing applications for Linux. Yes, Kino is promising, but its user interface is still a mess and development is slow.

DV Assembler only touches the head and tail parts of the original video files that are needed to create the transition effects. The rest of the video is left untouched, which means zero quality loss.

DV Assembler can also be used to generate video editing scripts that can be run without KDE and Kommander.

RMovie is a Ruby extension for accessing and retrieving information from video and audio files.

RMovie can access many video formats (.mov, .avi, .mpg, .wmv, etc.) and can output movie frames to RMagick as images.

Installation:

# build the quadrupel objects
cd quadrupel
make
cd ..

# build the rmovie extension
ruby extconf.rb
make

# install extension
[ become root ]
make install

Rainbyte Video Converter is a Kommander script which helps you convert video and audio in an easy way.

Its based on Kommander, mencoder and ffmpeg and you can convert from/to any format supported by those programs.

Well, I hope that it will be usefull for you, thanks for all.

Many users prefer Gnome Window Manager but cant go without Amarok. Gnome Play Video in Totem allows Gnome Users to view video or audio externally in Totem.

This is very useful for Video Podcasts.

Ubuntu Studio project is a multimedia creation flavor of Ubuntu.

Ubuntu Studio is aimed at the GNU/Linux audio, video and graphic enthusiast as well as professional.

We provide a suite of the best open-source applications available for multimedia creation. Completely free to use, modify and redistribute. Your only limitation is your imagination.

Audio

Our aim is to assemble suites of applications aimed at creative people. Suites including the best open-source applications available.
For instance, Ardour 2 - A multitrack recorder/editor geared toward people familiar with Pro-Tools.

Graphics

Graphic design and modeling applications including The GIMP, Inkscape and Blender. Along with plugins like dcraw to help with RAW camera files and wacom-tools for people with Wacom drawing tablets.

Video

PiTiVi, Kino, Cinepaint are included for video creation. We hope to provide a creative environment to people as well as give a spotlight to some amazing open-source applications.

Let the creativity fly...

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.
