Previously, all link-time dependencies were added for all libraries, resulting in bogus link-time dependencies since not all dependencies are shared across libraries. Also, in some cases like libavutil, not all dependencies were taken into account, resulting in some cases of underlinking. To address all this mess a machinery is added for tracking which dependency belongs to which library component and then leveraged to determine correct dependencies for all individual libraries.
Libav
Libav is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Tools
- avconv is a command line toolbox to manipulate, convert and stream multimedia content.
- avplay is a minimalistic multimedia player.
- avprobe is a simple analisys tool to inspect multimedia content.
- Additional small tools such as
aviocat,ismindexandqt-faststart.
