Free dv software for linux

Dvgrab receives the audio and video data from a digital camcorder via the ieee1394 interface and stores into an AVI file. It features autosplit of long video sequences into several files, and supports saving the data as raw frames, AVI type 1 and AVI type 2.
To use the program, turn on the camera, press play, and run the command in a terminal:
dvgrab --frames 200 myfilm-
If you have properly configured your kernel and your ieee1394 device drivers, you should end up with about 30 MByte of DV image data nicely packed in a file myfilm-001.avi (digits and extension automatically appended), which can be displayed with the Microsoft Media Player or a similar program (remember to install the required DV codecs, software
should be included with your hardware).
Read the man page for more documentation or dvgrab --help. Please submit bug reports, fixes, or suggestions to http://bugzilla.schirmacher.de/ or access the discussion forum
at http://kino.schirmacher.de/. Be sure to read the NEWS file for very helpful release notes.
Enhancements:
- riff.cc, riff.h, avi.cc, avi.h, endian_types.h (added): make RIFF and AVI classes endian and architecture safe (Daniel Kobras).

gdvrecv is a set of tools for FreeBSD to receives audio and video data from a digital camcorder via an IEEE 1394 (widely known as FireWire) link and stores them into an DV file.
This software package is composed by :
- firewire, a Python module for the FreeBSD firewire sub system
- dvrecv, a command line tool to receive a DV stream
- gdvrecv, a Gtk tool to receive a DV stream
- Basicaly, gdvrecv does the same thing as the fwcontrol -R command, but is more user-friendly.
- You can use Kino (FreeBSD port: multimedia/kino) for editing the DV files recorded with gdvrecv.
- Note : gdvrecv is written for FreeBSD 5.3 or better. Other operating systems or FreeBSD versions are not supported (but youre welcome to send me patch for other operating systems).

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.

Kdenlive is a non-linear video editor for KDE. Kdenlive project provides all project management and editing tools while relying on a separate rendering program (currently PIAVE) to perform the editing operations.
Support is planned for transitions, effects, multiple file formats, and full project and asset management support. The current beta release is capable of editing raw DV or AVI DV files, with tools such as move, razor, and resize, selecting parts of clips using in/outpoints, and exporting the result to another raw DV file.
You may playback/preview the contents of the timeline at any point during the edit. Full project save/load is supported.
Enhancements:
- New image formats
- Added support for gimp xcf and exr.
- Other supported formats are: png, jpeg, gif (non animated), xcf, exr, tiff, svg, mp3, vorbis, wav, flash, mpeg, avi, dv, wmv,... You can even insert another Kdenlive project in the timeline!
- Effects and Transitions
- Many fixes, and effects and transitions can now be copied from a clip to another.
- Export formats
- Theora export is now available if FFMPEG was compiled with theora support.
- Timeline
- Improved markers, allow insertion of of several clips in one operation, added "remove empty space" feature, multi clip selection tool
- Metadata
- Kdenlive can now read and write metadata in video and audio files

- Project management
- User can define a frame that will be used as thumbnail for each video clip in the project
- General
- Many fixes to the undo / redo system, lots of ui fixes and enhancements

reacTIVision is an open source, cross-platform computer vision framework for the fast and robust tracking of fiducial markers in a real-time video stream. reacTIVision project was mainly designed for the rapid development of table-based tangible user interfaces.

Its tracking core is using Ross Bencinas fidtrack library which is basically a newer high-performance implementation of Enrico Costanzas original d-touch concept. This framework was developed by Martin Kaltenbrunner et.al. at the Music Technology Group, IUA, UPF in Barcelona, Spain as part of the reacTable* project, a novel electro-acoustic musical instrument with a tangible user interface.

reacTIVision is a standalone application, which sends OpenSound Control messages via a UDP network socket to any connected client application. It implements the TUIO protocol, which was specially designed for transmitting the state of tangible objects on a table surface. This framework includes a set of free example client projects for various programming languages, which serve as a base for the easy development of tangible-user interface applications.

The reacTIVision application compiles and runs under the follwing operating systems: Win32, MacOS X and Linux. Under Win32 it suports any camera with a proper WDM driver, such as USB, USB2, FireWire and DV cameras. Equally under MacOS X any such camera supported by QuickTime will work in reacTIVision. Under Linux, FireWire cameras are best supported, as well as a few Video4Linux USB cameras.

NEW: Support the reacTIVision project and buy T-Shirts, posters and other merchandise featuring the reacTIVision fiducial symbols in our web-shop! All designs on these products can be recognized and tracked by the actual reacTIVision software.

Application Handling

Before starting the reacTIVision application make sure you have a supported camera connected to your system. The application can and will not work at all without a camera. Under Win32 and MacOS X the application will ask to select and configure the camera upon startup. Under Linux the camera will be selected automatically. Once configured the application will show a video window with the current camera image in black&white.

Pressing T will show the binary tresholded image, pressing the N key will turn the display off, which reduces its CPU usage significantly!

Pressing the S key will return to the original source image. For convenience and debugging porposes hitting the R key saves a raw image frame, while hitting the B key will save an image in the BMP format.

The P pauses the image analysis completely, hitting ESC will quit the application. The F key toggles the diplay of FPS info in the titlebar. In order to produce some more verbose debugging output, hitting the V key will print the currently recognized symbols to the console.

Command Line Options

The reacTIVision application per default sends the TUIO messages to port 3333 on localhost (127.0.0.1)

In order to change these parameters you can invoke the application with the -h [ip-address] and -p [port-no] options.

reacTIVision needs a so called "tree file" in order to function properly. The default "all.trees" is included and loaded automatically. If you want to use you own tree file you can invoke the application with the -t [tree-file] option.

Optionally if you dont want to analyze the complete image - for example in a square or round table setup - the application can mask a part of the video image with a black region, which speeds up the segmentation algorithm. In order to apply this mask You can invoke the application with the -m [square,circle] option.

Applying the -h or -help option will print a usage message to the console.

Calibration and Distortion

Some tables, such as the reacTable are using a convex mirror in order to increase the area visible to the camera at a minimal distance. This mirror as well as a fish-eye lens unfortunately distort the image. reactIVision includes a correction algorithm, which corrects this distortion with the help of a so called "grid file". These grid files can be generated during a prior calibration process.

To calibrate reacTIVision invoke the application with the option: reacTIVision -c 9 -g [grid_file]

In order to use the this calibration invoke the application with: reacTIVision -g [grid_file]

Coriander project is the Linux graphical user interface (GUI) for controlling a Digital Camera through the IEEE1394 bus (aka FireWire, or iLink).
Coriander is full featured and besides changing the parameters of the camera it will also let you record video, send images to an FTP site, convert the video to a V4L stream,... A live display is of course provided too.
Best of all, Coriander will work with any camera that is compatible with the IIDC specifications (also known as DCAM specs). This includes most 1394 webcams and a majority of industrial or scientific cameras too.
However, any cameras in which you can insert a video tape (camcorders,...) will NOT work with coriander. These cameras record compressed DV video on the tape, while the IIDC specify uncompressed, on-the-fly video flows.
Main features:
- change picture mode and format.
- camera on/off/reset
- control of Auto/man/one-push-auto, on/off, value and absolute value for all standard features
- memory channel save/load
- full Format_7 control
- control of the external trigger
- transmission on/off/restart
Enhancements:
- Upgrade the framerate calculation to use the timestamps sent by the kernel (through libdc1394)
- Add a counter that shows dropped frames warnings. A warning is issued when the difference between a pervious period and a new period is larger than 50%.
- fixed the bit depth. If the bit depth is available in the camera, it will be used. Otherwise the manual control will be available. I still have problems with my Basler 602f though. It has 10bits but the image is not good: saturated regions appear mid-grey (128) and the other regions are noise.
- sync with libdc1394 (SVN 391)
- fixed missing string in trigger_source_list
- sync with libdc1394
- add more details to configure messages
- added PIO, SIO and strobe direct register read/write
- remove spurious debug messages
- revert part of the change of Feb. 1st regarding the Flea 2 because some other manufacturers implementation systematically fail one of the tests.
- fixed wrong argument order of WritePVNHeader(). Thanks to John Shen.
- Disable features if they dont support any control mode or if they are OFF and their power cant be controlled. This solves a few issues we had with the Flea 2 from Point Grey.
- little update of the "About" window
- dont set 1394b at boot time: let the user do it manually.
- move and fix `extern declarations of string arrays from build_menus.c, build_ranges.c, thread_save.c, tools.c, update_frames.c and update_ranges.c to coriander.h
