How to Install QMediainfo in Ubuntu 11.04 Natty Narwhal?

Both audio and video (images too) have a "secret" place called the Meta-Tag in which they hold information such as Artist/Album/Year, etc or if it's a picture the camera that captured it, etc ... type information that can be read by your OS once the proper applications are installed.

This information can be accessed via the the File manager of your Operating system. Concerning GNU/Linux, well after you install the proprietary codec pack, the OS can read certain amount of those details, say using the Nautilus file manager, but there are dedicated applications that lets you read/extract a lot of other advanced details.

There is a such an application called Mediainfo that has the ability to read advanced information from the container format of audio/video and even image files and lets you easily see them. If you use MS Windows then Mediainfo comes as a part of the excellent K-Lite codec pack but I don't think that we can easily install its GUI (although the command-line version is available via a PPA) in GNU/Linux.  

So I think after facing the same problem as others who tried to "extract" advanced info from multimedia files, I guess that a developer decided to use the already existing mediainfo command-line libraries and create a GUI front-end in Qt toolkit that is called QMediainfo!.

Qmediainfo lets you read advanced technical information from audio/video files such as ...

*. Year/Track/Artist/Category.


*. Bitrate related info such as - Max/Min and overall bitrate (average).

*. Screen resolution.

*. Encoding app/library.

*. Comments and ratings.

*. Codec ID.

*. Duration.

*. Aspect ratio.

*. Frames per second.

*. Audio channels, sample-rate, etc.

*. Language. 

*. Subtitles

*. Save the date to text/HTML file ... are just a few to mention.


As said it's written in the Qt-4 toolkit but works really well with Gnome desktop nonetheless. It depends on the Mediainfo library. So we'll have to make sure it's installed first. But we can just add the two PPA channels and the installation will take care the hassle for ya :).

You can install qmediainfo in Ubuntu 11.04 Natty Narwhal (10.04 and 10.10) by using the below commands in your GNU/Linux Terminal.
sudo add-apt-repository ppa:razrfalcon/qmediainfo

sudo apt-add-repository ppa:shiki/mediainfo

sudo apt-get update

sudo apt-get install qmediainfo
That should do it. Unfortunately whenever you want these advanced information, you'll have to separately launch the app and drag-n-drop the files into it because it does not integrate to the Nautilus File manager (don't know how its with Dolphin - The KDE file manager :D).

You can start the app by searching for "qmediainfo" in Unity dash or use it in the command box (use "Alt" + "F2" keys). Big thanks to the developer. Nice work, love it.

VideoCatcher - A Qt Powered TV Viewer for KDE4!

When it comes to downloading and viewing on-line TV videos there are few bloody good apps for GNU/Linux. But some are separate projects (non official projects of Gnome or KDE), although there's nothing wrong with that, but for all you KDE4 users, according to the developer, Videocatcher is actually the only TV viewer available for KDE4 at the moment!.

It's very similar to the excellent Miro ... but as said, it's especially designed for KDE4 geeks.

Main features...

*. Well, as said it is an online TV channel viewer.

*. Lets you view/add-subscribe/edit video casts via: RSS/Atom feeds, etc.

*. Downloading videos.


*. Can also be used as a podcast client.

*. Written in Qt4 toolkit.

Although there isn't a ".deb" package for Kubuntu/Ubuntu 11.04 at the moment but I think the Ubuntu 10.04 should work on 11.04. Not just in Ubuntu but you can install Videocatcher in other GNU/Linux distributions such as OpenSuse and Mandriva as well.

For that please visit this opendesktop page for more.

If the ".deb" package does not work for you then you can try compiling it in Kubuntu 11.04. For that use the below commands.

First download the source-code.
svn co svn://svn.kde.org/home/kde/trunk/playground/network/videocatcher
Now get the dependencies.
sudo apt-get install kdepimlibs5-dev libqt4-sql-sqlite libboost-dev
Let's compile (yikes :P)

tar xjf videocatcher-0.1.x.tar.bz2
 cd videocatcher-0.1.x
 mkdir build
 cd build
 cmake .. -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix`
 make
       
Finally, issue the below command to install it.
make install
Good luck.
