Libav is a complete, cross-platform solution to decode, encode, record, convert and stream audio and video.

this is the codec library from libav (both encoding and decoding).

this package is a replacement for the regular libavcodec54 library package; it contains the following additional codecs:

* opencore adaptive multi-rate (amr) narrow-band (encoder/decoder)
* opencore adaptive multi-rate (amr) wide-band (decoder)
* android visualon aac (encoder)
* android visualon adaptive multi-rate (amr) wide-band (encoder)
because this package links against libraries that are licensed under apache license 2.0, the resulting binaries are distributed under the gpl version 3 or later.
