Theora and related libraries +can be gotten from www.theora.org or the main Xiph.Org site at +www.xiph.org. Development source is kept in an open subversion +repository, see http://theora.org/svn/ for instructions. + +------------------------------------------------------------------------- +Getting started with the code +------------------------------------------------------------------------- + +*** What do I need to build the source? + +Requirements summary: + + For libtheora: + + libogg 1.1 or newer. + + For example encoder: + + as above, + + libvorbis and libvorbisenc 1.0.1 or newer. + + For creating a source distribution package: + + as above, + + Doxygen to build the API documentation, + pdflatex and fig2dev to build the format specification + (transfig package in Ubuntu). + + For the player only: + + as above, + + SDL (Simple Direct media Layer) libraries and headers, + OSS audio driver and development headers. + +The provided build system is the GNU automake/autoconf system, and +the main library, libtheora, should already build smoothly on any +system. Failure of libtheora to build on a GNU-enabled system is +considered a bug; please report problems to theora-dev@xiph.org. + +Windows build support is included in the win32 directory. + +Project files for Apple XCode are included in the macosx directory. + +There is also an experimental scons build. + +*** How do I use the sample encoder? + +The sample encoder takes raw video in YUV4MPEG2 format, as used by +lavtools, mjpeg-tools and other packages. The encoder expects audio, +if any, in a separate wave WAV file. Try 'encoder_example -h' for a +complete list of options. + +An easy way to get raw video and audio files is to use MPlayer as an +export utility. The options " -ao pcm -vo yuv4mpeg " will export a +wav file named audiodump.wav and a YUV video file in the correct +format for encoder_example as stream.yuv. Be careful when exporting +video alone; MPlayer may drop frames to 'keep up' with the audio +timer. The example encoder can't properly synchronize input audio and +video file that aren't in sync to begin with. + +The encoder will also take video or audio on stdin if '-' is specified +as the input file name. + +There is also a 'png2theora' example which accepts a set of image +files in that format. + +*** How do I use the sample player? + +The sample player takes an Ogg file on standard in; the file may be +audio alone, video alone or video with audio. + +*** What other tools are available? + +The programs in the examples directory are intended as tutorial source +for developers using the library. As such they sacrifice features and +robustness in the interests of comprehension and should not be +considered serious applications. + +If you're wanting to just use theora, consider the programs linked +from http://www.theora.org/. There is playback support in a number +of common free players, and plugins for major media frameworks. +Jan Gerber's ffmpeg2theora is an excellent encoding front end. + +------------------------------------------------------------------------- +Troubleshooting the build process +------------------------------------------------------------------------- + +*** Compile error, such as: + +encoder_internal.h:664: parse error before `ogg_uint16_t' + +This means you have version of libogg prior to 1.1.
