This repository contains a SMPTE 2042-1 VC-2 reference encoder and

decoder. It can be compiled using autotools on Linux or Windows and

includes the following executables once compiled:

 o EncodeStream -- an encoder which will encode a VC-2 compliant stream

   using one of the supported LD or HQ profiles.

 o DecodeStream -- a decoder which will decode a VC-2 compliant stream

   which complies with the LD or HQ profiles.

The EncodeStream tool supports the following profiles:

 o HQ_CBR -- an encoder for the High Quality (HQ) profile of

   VC-2 which encodes at a constant bit rate.

 o HQ_ConstQ -- an encoder for the High Quality (HQ) profile of

   VC-2 which encodes with a constant quantiser value.

 o LD -- an OBSOLETE encoder for the Low Delay (LD) profile of VC-2.

   (included for backwards compatibility).

In addition, an optional utility (DecodeFrame) is includeded which

takes in the compressed bytes of a VC-2 frame without any surrounding

headers. This is not compiled by default but can be enabled with the

--enable-frame-decoder flag (./configure --enable-frame-decoder).

The googletest testing framework can be used to run tests on the

repository. This requires the googletest submodule to be added by

  git submodule init

  git submodule update

(or using --recurse-submodules when cloning)

Then using `make check' to build and run the tests.

Additional help on each executable will be printed if it is run with

the --help parameter.
