+How To Extract Images From Videos Using ffmpeg
+================================================================================
+Hi unixmen readers,
+
+Have you ever wanted to extract images from a video file? It is possible to do such thing in Linux and for this tutorial I will use ffmpeg to get images from a video.
+
+### What is ffmpeg? ###
+
+ffmpeg is a very useful command line program which can be used to transcode media files. It is part of the FFmpeg leading multimedia framework that has many functionalities such as the ability to  decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created.
+
+There are many various tools included in the framework each of which has a specific role. For example the ffserver is used to stream multimedia for live broadcasts, ffprobe is used to analyze multimedia stream, ffplay can be used as a simple media player and **ffmpeg** has the ability to convert multimedia files between formats.
+
+If you are interested the followings are the developer libraries included in the FFmpeg framework:
+
+- libavutil is a library containing functions for simplifying programming, including random number generators, data structures, mathematics routines, core multimedia utilities, and much more.
+- libavcodec is a library containing decoders and encoders for audio/video codecs.
+- libavformat is a library containing demuxers and muxers for multimedia container formats.
+- libavdevice is a library containing input and output devices for grabbing from and rendering to many common multimedia input/output software frameworks, including Video4Linux, Video4Linux2, VfW, and ALSA.
+- libavfilter is a library containing media filters.
+- libswscale is a library performing highly optimized image scaling and color space/pixel format conversion operations.
+- libswresample is a library performing highly optimized audio resampling, rematrixing and sample format conversion operations.
+
+**Note**: ffmpeg and FFmpeg are not the same. FFmpeg is the framework and the ffmpeg one of the utilities included on it.
+
+### Let the action begin ###
+
+In order to follow this tutorial you need to install the ffmpeg command line utility in your linux machine. Ubuntu users can easily install the ffmpeg utility by typing and running the following command in their terminal.
+
+    sudo apt-get install ffmpeg
+
+Fedora users can install ffmpeg directly from the repos.
+
+    yum install ffmpeg
+
+Or you can compile it from source. Before compiling and installing it from source you need to download it from the official website with the help of the following command.
+
+    wget http://www.ffmpeg.org/releases/ffmpeg-2.2.3.tar.bz2
+
+Extract the archive with the following command.
+
+    tar -xvjf ffmpeg-2.2.3.tar.bz2
+
+Once the archive is extracted run the following command.
+
+    ./configure
+    make
+
+Once the compile is finished run the following command to install ffmpeg.
+
+    su -c 'make install'
+
+Not that everything is set up, all you have to is type a few commands in your terminal and you will be able to extract images from any type of video file.
+
+Before going any further make sure you are in the same directory with the video file from which you want to extract images from. Use the cd command to navigate to the right directory. Since the video I am using for the purpose of this tutorial is in my Desktop i use the following command to navigate to my desktop.
+
+    cd /home/oltjano/Desktop
+
+Then I use the following command to extract images from my video file.
+
+    ffmpeg -i "Тимати - Рентген ( Альбом '13')-C9Plztvv8ac.mp4" -r 1 -q:v 2 -f image2 image-3%d.jpeg
+
+The **-i** option serves to get the input which in my case is the video file named **Тимати – Рентген ( Альбом ’13′)-C9Plztvv8ac.mp4**, the -r option sets the number of frames to be extracted as images every second. I like to extract one frame every second.
+
+Then a very important option that should be mentioned and I like to use is the -q:v which is used to set the image quality of the images being extracted. I always get high quality images when extracting them from a video by using the value of 2.

+
+Hi linux geeks,
+
+In this short tutorial, I will teach you how to install a very nice app for the 2014 FIFA World Cup in your Linux distribution. The application is called iCup and is available for Windows, Mac and Linux.
+
+It has been a very long time since I have watched a football match so I thought to install this app on my machine to stay updated with the latest statistics on World Cup 2014. I don’t want to look like an ignorant regarding football in front of my friends. The iCup application can provide information on matches schedule, scorers, team coaches and formations of every match. There are also real time updates that give you the latest data during the matches.
+
+### It supports the following features: ###
+
+- Fully localizable on the fly in about 30 languages (use the language menu into the option panel)
+- Exclusive flexible user interface that adapt the data size to the window dimensions
+- Searchable matches calendar also groupable by day or stage
+- Graphical visualization of groups and 2° stage
+- Support for the conversion of the matches dates and time based on your local timezone and your system format.
+- Direct linking for commenting the results into your preferred social network (Facebook, Google+ and Twitter)
+- Proxy support (basic and digest authentication method supported)
+
+I have tested it on my Ubuntu 12.04 LTS system and it works great. I have not experienced any errors or crashes so far. You can easily install this great app on your system by grabbing a copy of it on the [official website][1] and then extract the archive on your favourite destination. Once the archive is extracted, double click on iCup 2014 FREE – Brazil and the app will open.
+
+iCup is very useful to me, I hope you find it useful too.
