This README covers the Ogg Vorbis 'Tremor' integer playback codec
|
|
source as of date 2002 09 02, version 1.0.0.
|
|
|
|
******
|
|
|
|
The C source in this package will build on any ANSI C compiler and
|
|
function completely and properly on any platform. The included build
|
|
system assumes GNU build system and make tools (m4, automake,
|
|
autoconf, libtool and gmake). GCC is not required, although GCC is
|
|
the most tested compiler. To build using GNU tools, type in the
|
|
source directory:
|
|
|
|
./autogen.sh
|
|
make
|
|
|
|
Currently, the source implements playback in pure C on all platforms
|
|
except ARM, where a [currently] small amount of assembly (see
|
|
asm_arm.h) is used to implement 64 bit math operations and fast LSP
|
|
computation. If building on ARM without the benefit of GNU build
|
|
system tools, be sure that '_ARM_ASSEM_' is #defined by the build
|
|
system if this assembly is desired, else the resulting library will
|
|
use whatever 64 bit math builtins the compiler implements.
|
|
|
|
No math library is required by this source. No floating point
|
|
operations are used at any point in either setup or decode. This
|
|
decoder library will properly decode any past, current or future
|
|
Vorbis I file or stream.
|
|
|
|
********
|
|
|
|
The build system produces a static and [when supported by the OS]
|
|
dynamic library named 'libvorbisidec'. This library exposes an API
|
|
nearly identical to the BSD reference library's 'libvorbisfile',
|
|
including all the features familiar to users of vorbisfile. This API
|
|
is similar enough that the proper header file to include is named
|
|
'ivorbisfile.h' [included in the source build directory]. Lower level
|
|
libvorbis-style headers and structures are in 'ivorbiscodec.h'
|
|
[included in the source build directory]. A simple example program,
|
|
ivorbisfile_example.c, can be built with 'make example'.
