There are many command line wireless scanner tools available for Linux, which requires command line knowledge to deal with them. Also there are some GUI tools available for Linux which scans wireless network around your wireless device like iwScanner, etc.
LinSSID is great application designed from scratch using C++, Qwt, and Qt languages, it is similar to iwScanner and Inssider (for MS Windows). LinSSID displays the information available from iwlist tool in graphical format. LinSSID displays a table of all of the local wireless networks that your device can receive, and information about them. It also displays charts of the signal strength of each network by channel number and over time. LinSSID will work with more than one wireless device attached to a system, but only one at a time (selectable).
LinSSID requires root privilege to run the iwlist tool. It can be run in one of two ways to do this. The preferred method is to launch LinSSID as a regular user and let it ask for a password. It will then use the password to get iwlist information, but LinSSID itself will not run with root privilege. Alternately, LinSSID can be launched with root privilege. This second method is less secure since any misbehaving code in the program could possibly have detrimental effects on the system.
It is multi-threaded, using the main thread to communicate with the main window and the user while a second worker thread keeps a named pipe filled with iwlist data. The program is in active development, so if you find any bug report it to the developer following this link.

FFmpeg is popular multimedia framework, that allows users to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. It contains libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale and libswresample which can be used by applications. As well as ffmpeg, ffserver, ffplay and ffprobe which can be used by end users for transcoding, streaming and playing. It is a complete, cross-platform solution to record, convert and stream audio and video.
FFmpeg security is a high priority and code review is always done with security in mind. Though due to the very large amounts of code touching untrusted data security issues are unavoidable and thus developers provide as quick as possible updates to last stable releases when new security issues are found.
Since "Ubuntu 14.04 Trusty" FFmpeg is dropped and its fork adopted 'libav' which made a lot of application unusable under Ubuntu 14.10 Utopic/14.04 Trusty. In coming release '15.04' Ubuntu team decided to add FFmpeg again to its repositories, so there won't be such issues like we have with 14.04/14.10 but there are unofficial FFmpeg PPAs available for Ubuntu 14.10 Utopic/14.04 Trusty. Now unusable applications can be used again on Ubuntu 14.10/14.04 using FFmpeg and if you want to use FFmpeg from command line then follow this official documentation.

FFmpeg offers following functionality with libs:
  • 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.

You can also follow this guide to build from source.

There are two unofficial PPAs available to install FFmpeg in Ubuntu 14.10/14.04. A PPA by Kyrill offers packages for 14.10 Utopic and 14.04 Trusty/Linux Mint 17.1/17
