1 # Ogg 2 3 [](https://travis-ci.org/xiph/ogg) 4 [](https://mf4.xiph.org/jenkins/job/libogg/) 5 [](https://ci.appveyor.com/project/rillian/ogg) 6 7 Ogg project codecs use the Ogg bitstream format to arrange the raw, 8 compressed bitstream into a more robust, useful form. For example, 9 the Ogg bitstream makes seeking, time stamping and error recovery 10 possible, as well as mixing several sepearate, concurrent media 11 streams into a single physical bitstream. 12 13 ## What's here ## 14 This source distribution includes libogg and nothing else. Other modules 15 (eg, the modules libvorbis, vorbis-tools for the Vorbis music codec, 16 libtheora for the Theora video codec) contain the codec libraries for 17 use with Ogg bitstreams. 18 19 Directory: 20 21 - `src` The source for libogg, a BSD-license inplementation of the public domain Ogg bitstream format 22 23 - `include` Library API headers 24 25 - `doc` Ogg specification and libogg API documents 26 27 - `win32` Win32 projects and build automation 28 29 ## Contact ## 30 31 The Ogg homepage is located at https://www.xiph.org/ogg/ . 32 Up to date technical documents, contact information, source code and 33 pre-built utilities may be found there. 34 35 ## Building ## 36 37 #### Building from tarball distributions #### 38 39 ./configure 40 make 41 42 and optionally (as root): 43 44 make install 45 46 This will install the Ogg libraries (static and shared) into 47 /usr/local/lib, includes into /usr/local/include and API 48 documentation into /usr/local/share/doc. 49 50 #### Building from repository source #### 51 52 A standard svn build should consist of nothing more than: 53 54 ./autogen.sh 55 ./configure 56 make 57 58 and as root if desired : 59 60 make install 61 62 #### Building on Windows #### 63 64 Use the project file in the win32 directory. It should compile out of the box. 65 66 #### Cross-compiling from Linux to Windows #### 67 68 It is also possible to cross compile from Linux to windows using the MinGW 69 cross tools and even to run the test suite under Wine, the Linux/*nix 70 windows emulator. 71 72 On Debian and Ubuntu systems, these cross compiler tools can be installed 73 by doing: 74 75 sudo apt-get mingw32 mingw32-binutils mingw32-runtime wine 76 77 Once these tools are installed its possible to compile and test by 78 executing the following commands, or something similar depending on 79 your system: 80 81 ./configure --host=i586-mingw32msvc --target=i586-mingw32msvc --build=i586-linux 82 make 83 make check 84 85 (Build instructions for Ogg codecs such as vorbis are similar and may 86 be found in those source modules' README files) 87 88 ## Building with CMake ## 89 90 Ogg supports building using [CMake](http://www.cmake.org/). CMake is a meta build system that generates native projects for each platform. 91 To generate projects just run cmake replacing `YOUR-PROJECT-GENERATOR` with a proper generator from a list [here](http://www.cmake.org/cmake/help/v3.2/manual/cmake-generators.7.html): 92 93 mkdir build 94 cd build 95 cmake -G YOUR-PROJECT-GENERATOR .. 96 97 Note that by default cmake generates projects that will build static libraries. 98 To generate projects that will build dynamic library use `BUILD_SHARED_LIBS` option like this: 99 100 cmake -G YOUR-PROJECT-GENERATOR -DBUILD_SHARED_LIBS=1 .. 101 102 After projects are generated use them as usual 103 104 #### Building on Windows #### 105 106 Use proper generator for your Visual Studio version like: 107 108 cmake -G "Visual Studio 12 2013" .. 109 110 #### Building on Mac OS X #### 111 112 Use Xcode generator. To build framework run: 113 114 cmake -G Xcode -DBUILD_FRAMEWORK=1 .. 115 116 #### Building on Linux #### 117 118 Use Makefile generator which is default one. 119 120 cmake .. 121 make 122 123 ## Testing ## 124 125 This package includes a collection of automated tests. 126 Running them is not part of building nor installation but optional. 127 128 ### Unix-like System or MinGW ### 129 130 If build under automake: 131 132 make check 133 134 If build under CMake: 135 136 make test 137 138 or: 139 140 ctest 141 142 ### Windows with MSBuild ### 143 144 If build with configuration type "Debug", then: 145 146 ctest -C Debug 147 148 If build with configuration type "Release", then: 149 150 ctest -C Release 151 152 ## License ## 153 154 THIS FILE IS PART OF THE OggVorbis SOFTWARE CODEC SOURCE CODE. 155 USE, DISTRIBUTION AND REPRODUCTION OF THIS LIBRARY SOURCE IS 156 GOVERNED BY A BSD-STYLE SOURCE LICENSE INCLUDED WITH THIS SOURCE 157 IN 'COPYING'.
