FFMpeg2.4.2 on Ubuntu14.04

FFmpeg 2.4 “Fresnel” – is the leading multimedia framework, cross-platform solution that is used to decode, encode, transcode, mux, demux, stream, filter and play any audio or video files. It includes libavcodec – the leading audio/video codec library. The most important thing in this release is the major version bump of the libraries. This means that this release is neither ABI-compatible nor fully API-compatible. But on the other hand it is aligned with the Libav release series, and will as a result probably end up being maintained for a long time.
