2Schroedinger
3============
4
5Schroedinger (or "schro" for short) is an implementation of the
6Dirac and SMPTE VC-2 video compression specification.  Dirac was
7developed by BBC Research & Development (http://www.bbc.co.uk/rd/)
8as an open technology with open licensing.

11Schroedinger is the C library implementing video encoding and
12decoding.  Most end users will want to use an application that
13uses the Schroedinger library for encoding and decoding Dirac
14streams.  A few such applications are Totem, VLC, and Mplayer.
15In addition, media frameworks such as GStreamer and decoding
16libraries such as ffmpeg can be configured to use Schroedinger
17either internally or via plugins.

20Schroedinger requires Orc (the Oil Runtime Compiler) in order to
21processing.  Orc is a library that generates SIMD code at runtime
22based on simple rules and configurable parameters.  Information
23about Orc can be found here:

26
27
28Schroedinger uses pkg-config both for finding Orc, and for allowing
29other build systems to find it.  If you are having trouble with
30configure scripts not finding Orc or Schroedinger, you probably need
31to set the PKG_CONFIG_PATH environment variable (substitute /usr/local
32as necessary):
33
34  export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

37Schroedinger has a mailing list:

42   o-umlaut "ö".)
