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

NVIDIA is well-known company all over the world regarding gaming cards. Sometimes it is really difficult to configure manufacturer drivers for NVIDIA cards in Linux, there could be many reasons for this such as kernel upgrade, and so. By default Ubuntu use the open source video driver Nouveau for NVIDIA graphics card. This driver lacks support for 3D acceleration and may not work with the very latest video cards or technologies from NVIDIA. An alternative to Nouveau are the closed source unified NVIDIA drivers, which are developed by NVIDIA. This driver provides excellent 3D acceleration and video card support.
If you are tired of compiling drivers and kernels then use xorg-edgers PPA to install latest drivers for NVIDIA graphics card and get high performance from your card. This PPA xorg-edgers is up-to-date among others and offers old and latest drivers for different kind of NVIDIA cards, which means you can choose to install what is best performing driver for your card. In latest drivers if you encounter any kind of issue, you can directly submit bug reports to NVIDIA, in order to fix that issue in future releases.
Nvidia Ubuntu

Release Notes for 352.30 & 346.16 drivers
  • Added support for the following GPU: GeForce 910M
  • Fixed a bug that caused poor video post-processing performance in VDPAU when operating on a large number of video streams simultaneously.
  • Fixed a bug that could cause an Xid error when terminating a video playback application using the overlay presentation queue in VDPAU.
  • Updated nvidia-installer to avoid recursing too deeply into kernel source trees under /usr/lib/modules, mirroring an existing restriction on recursion under /lib/modules.
  • Fixed a rare deadlock condition when running applications that use OpenGL in multiple threads on a Quadro GPU.
  • Fixed a kernel memory leak that occurred when looping hardware - accelerated video decoding with VDPAU on Maxwell-based GPUs.
  • Fixed a bug that caused the X server to crash if a RandR 1.4 output provided by a Sink Output provider was selected as the primary output on X.Org xserver 1.17 and higher.
  • Fixed a bug that caused waiting on X Sync Fence objects in OpenGL to hang indefinitely in some cases.
  • Fixed a bug that prevented OpenGL from properly recovering from hardware errors or sync object waits that had timed out.
  • Added support for the following GPUs: GeForce GTX 970M, GeForce GTX 980M
  • Fixed a bug that caused a blank screen when setting a mode requiring YUV 4:2:0 compression. These modes are not currently supported.
  • Fixed a bug that caused an incorrect DisplayPort link configuration to be displayed after a hotplug or unplug.
  • Added support for decoding VP8 video streams using the NVCUVID API on GPUs with VP8 hardware decode support.
  • Added support for the following EGL extensions: EGL_EXT_device_base, EGL_EXT_platform_device, EGL_EXT_output_base
  • Added the ability to increase the operating voltage on certain GeForce GPUs in the GeForce GTX 400 series and later. Voltage adjustments are done at the user's own risk. See the documentation on the "CoolBits" X configuration option in the README for details.
  • Added support for NVENC on GeForce GPUs. For more details on the NVENC SDK, see:
  • https://developer.nvidia.com/nvidia-video-codec-sdk.
  • Removed a sanity check in nvidia-installer that tested the availability of POSIX shared memory. The NVIDIA GPU driver has not required POSIX shared memory since release 270.xx.
  • Added accelerated support for r8g8b8a8, r8g8b8x8, b8g8r8a8 and b8g8r8x8 RENDER formats.
  • Updated nvidia-settings to take advantage of GTK+ 3, when available. This is implemented by building the nvidia-settings user interface into separate shared libraries (libnvidia-gtk2.so, libnvidia-gtk3.so), and loading the correct one at run-time.
  • Added the nvidia-settings option --gtk-library to allow specifying the path of the directory containing the user interface library or the path and filename of the specific library to use.
  • Added support in nvidia-settings for a GTK+ 3 user interface on x86 and x86_64.
  • Added the nvidia-settings option --use-gtk2 to force the use of the GTK+ 2 UI library.
  • Updated nvidia-installer to install a file in the system's xorg.conf.d directory, when a sufficiently new X server is detected, to cause the X server to load the "nvidia" X driver automatically if it is started after the NVIDIA kernel module is loaded.
  • This feature is supported in X.Org xserver 1.16 and higher when running on Linux 3.9 or higher with CONFIG_DRM enabled.
  • Improved the performance of nvidia-installer by enabling the use of parallel make when building the NVIDIA kernel modules. The concurrency level can be set with the --concurrency-level option, and defaults to the number of detected CPUs.
  • Updated nvidia-installer to determine default installation locations for libraries based on the presence of known paths in the ldconfig(8) cache and the filesystem, rather than hardcoded distro-specific paths.
  • Fixed a GLSL compiler bug that would produce corruption when running games in Wine.
  • Fixed the EGL_KHR_stream_cross_process_fd extension.
  • Fixed rendering corruption that sometimes happened when calling
  • DrawElementsInstancedBaseVertexBaseInstance(),
  • DrawElementsInstancedBaseInstance(),
  • or DrawArraysInstancedBaseInstance().
  • Dramatically improved OpenGL Framebuffer Object creation performance.
  • Removed the limit on the maximum number of OpenGL Framebuffer Objects.
  • Updated the NVIDIA OpenGL driver to prefer $XDG_CACHE_HOME over $HOME as the default location for storing the GL shader disk cache.

Screen Blanks/Monitor Turns Off (Geforce Go card)
Using a laptop with a GeForce Go card, or connecting the sole display via DVI on a dual-head system sometimes results in the screen not receiving a picture. This is caused by the driver outputting video to the VGA port on the graphics card, instead of DVI.
The usual hint that you have this problem is when you hear the startup sound but nothing appears on the screen. If you do not hear any sound, you are more than likely experiencing unrelated problems.
Switch to the console by using CTRL+ALT+F1, or reboot and select recovery mode from the GRUB menu.
Open and edit xorg.conf like this: sudo nano /etc/X11/xorg.conf
Find the line that says: Section "Screen"
Insert a new line that says Option "UseDisplayDevice" "DFP"
Save the file. Use sudo reboot to restart your computer.
