Bombono DVD—Open-Source DVD Authoring Software (www.bombono.org/cgi-bin/wiki/Home)

Starting off this month we have Bombono: a simplistic DVD authoring program that doesn't have the steep learning curve of many others in its field. According to the Web site: “Bombono DVD is a DVD authoring program for Linux. It is easy to use and has nice and clean GUI (Gtk).”

Also from the Web site, the main features of Bombono DVD are:

  • Excellent MPEG viewer: timeline and monitor.

  • Real WYSIWYG menu editor with live thumbnails.

  • Comfortable drag-and-drop support.

  • You can author to folder, make ISO images or burn directly to DVD.

  • Reauthoring: you can import video from DVD discs.

Bombono DVD lets you author DVDs with ease, particularly with these easy-to-make menus that (actually) work.

I found that making chapter points in a video is actually really easy, and these chapters also can be linked to in your DVD menus.

Bombono already has reached the stage of maturity where it can make images and burn them to disc on the fly.

Installation

Binaries are available for Ubuntu, SUSE, ALT Linux and Arch Linux, along with the usual source tarball. For those compiling from source, there are some pretty stringent library requirements. The documentation lists the following:

In terms of packages I needed to install on my own Kubuntu system (obviously some were already in place), I needed: scons, libglibmm-2.4-dev, libxml++2.6-dev, libmjpegtools-dev, graphicsmagick, libgraphicsmagick1, libgraphicsmagick++1, libgraphicsmagick++1-dev and libgtkmm-2.4-dev.

Head to the Web site, grab the latest tarball, extract it and open a terminal in the new folder. Enter:

$ scons

If your distribution uses sudo, enter:

$ sudo scons install

If not, enter:

$ su 
# scons install

Once the compilation has finished, you will find it in your menu, or you can start Bombono with the command:

$ bombono-dvd

Usage

A quick note before we jump in: you can use only MPEG-2 .vob files. It's a bummer, I know, so if you have files such as some DivXes you want to include, you're going to have to convert them first. Hopefully, future releases will support DivX, Xvid, MPEG-4 and so on, but for now, you'll have to make do with just .vob support.

Once you have some .vob files available, start the program, click on the Source tab, and look at the file browser on your left. Locate the files you're going to use, and either drag them across into the Media List pane or click the blue + sign. While we're in the source section, clicking the Edit button when a video is highlighted lets you split the file into chapters using the timeline below (more on that later).

For now, let's move on to the menu tab. Click the + sign in the Menu List pane to create a new menu. Then, you can add a menu object to link to a video along with some accompanying text. To add a menu object, choose the shape of the object you want to add and click the + sign next to it. Once the object has been made, you can move it around the screen or resize it. Now, let's make a link to the video you want to run from the menu object.

Right-click on the object and choose Link→(name of video). Note that if you've edited your videos to include chapters, these chapters can be linked to also, but I don't have the space to cover that here.

Now, let's add some text. You'll be in the standard mode for manipulating the menu objects as signified by the highlighted mouse pointer, but press the T button (as in T for text), and you'll be ready to go. Click next to an object and you'll see a blinking cursor, ready for you to start typing. If you don't like the font size or color, you can change them in the above menu.

With a menu out of the way, let's get back to editing—more specifically, making chapters. Return to the Source tab, and make your way back to the Media List pane. Select the file to which you want to add chapters, and click the green Edit button. Your file now will load up in the big timeline below.

It appears that when you're editing for chapters, if it's not evident where you are from the still image on-screen, you need to play the video in a separate player and take note of what time each point is, as the video does not seem to play in the window itself (although I could be wrong and missing something obvious). However, I found this wasn't really a Herculean task, so it shouldn't be much of a worry.

In the timeline section, the top slider is for browsing around inside the video, where the on-screen image will update depending on the position in time. If you look to the left, the strong blue digital readout will give you the exact time the slider is sitting on. To mark out a chapter, click the blue button underneath the time readout (I'll call it a Chapter Marker), and a Chapter Point will be made under the slider, marked with the same icon as the Chapter Marker. If you want to fine-tune this position at all, you also can slide around the Chapter Point, and if you've made one accidentally, you can right-click and choose Delete Chapter Point.

When you're happy with your soon-to-be DVD, head to the Output tab. Here, you can choose either to write a DVD Folder or make a disk image on hard drive, or you can just burn the project straight to DVD.

Of course, this project has some hurdles to overcome before it's truly ready for the mainstream. The most pressing issue is that you can use only .vob files for now. This is reasonable enough, but when given the often tricky task of converting files, most lazy people like myself are going to throw the whole job in the too-hard basket and go back to playing Half-Life. It'll be truly ready only when you can add almost any video file. This, of course, will require some probable structural changes to the design and coding—perhaps adding a video conversion stage prior to burning—but it still will be necessary.

Nevertheless, the authors have taken a good approach that I respect—keeping it tight and simple to begin with and working properly with the elements they do have, instead of creating an unstable mess with lots of features. This project is simplistic and highly satisfying, and it probably will become a distro mainstay once it reaches fruition. I'm looking forward to the finished product.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Webinar
Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
