Timothy B. Terriberry 14920bae03 Make false continued packet handling consistent A false continued packet occurs if the previous page ended at the end of a packet, with no sequence number gap and no continued data on that page, while the current page has the continued packet flag set. Previously, if you drained all of the buffered packet data by repeatedly calling ogg_stream_packetout() after submitting the previous page but before submitting the current page, libogg would discard the continued data at the beggining of the current page. However, if you left the previous page's data in the buffer, then libogg would happily return the continued data at the start of the current page as a separate packet when you eventually did call ogg_stream_packetout(). This patch makes libogg consistently discard this data.		2017-06-16 15:01:08 -07:00

README.md

Ogg

Ogg project codecs use the Ogg bitstream format to arrange the raw, compressed bitstream into a more robust, useful form. For example, the Ogg bitstream makes seeking, time stamping and error recovery possible, as well as mixing several sepearate, concurrent media streams into a single physical bitstream.

What's here

This source distribution includes libogg and nothing else. Other modules (eg, the modules libvorbis, vorbis-tools for the Vorbis music codec, libtheora for the Theora video codec) contain the codec libraries for use with Ogg bitstreams.

Directory:

src The source for libogg, a BSD-license inplementation of the public domain Ogg bitstream format
include Library API headers
doc Ogg specification and libogg API documents
win32 Win32 projects and build automation
macosx Mac OS X project and build files

Contact

The Ogg homepage is located at https://www.xiph.org/ogg/ . Up to date technical documents, contact information, source code and pre-built utilities may be found there.

Building

Building from tarball distributions

./configure
make

and optionally (as root):

make install

This will install the Ogg libraries (static and shared) into /usr/local/lib, includes into /usr/local/include and API documentation into /usr/local/share/doc.

Building from repository source

A standard svn build should consist of nothing more than:

./autogen.sh
./configure
make

and as root if desired :

make install

Building on Windows

Use the project file in the win32 directory. It should compile out of the box.

Cross-compiling from Linux to Windows

It is also possible to cross compile from Linux to windows using the MinGW cross tools and even to run the test suite under Wine, the Linux/*nix windows emulator.

On Debian and Ubuntu systems, these cross compiler tools can be installed by doing:

sudo apt-get mingw32 mingw32-binutils mingw32-runtime wine

Once these tools are installed its possible to compile and test by executing the following commands, or something similar depending on your system:

./configure --host=i586-mingw32msvc --target=i586-mingw32msvc --build=i586-linux
make
make check

(Build instructions for Ogg codecs such as vorbis are similar and may be found in those source modules' README files)

Building with CMake

Ogg supports building using CMake. CMake is a meta build system that generates native projects for each platform. To generate projects just run cmake replacing YOUR-PROJECT-GENERATOR with a proper generator from a list here:

cmake -G YOUR-PROJECT-GENERATOR .

Note that by default cmake generates projects that will build static libraries. To generate projects that will build dynamic library use BUILD_SHARED_LIBS option like this:

cmake -G YOUR-PROJECT-GENERATOR -DBUILD_SHARED_LIBS=1 .

After projects are generated use them as usual

Building on Windows

Use proper generator for your Visual Studio version like:

cmake -G "Visual Studio 12 2013" .

Building on Mac OS X

Use Xcode generator. To build framework run:

cmake -G Xcode -DBUILD_FRAMEWORK=1 .

Building on Linux

Use Makefile generator which is default one.

cmake .
make
