alogg - an Ogg/Vorbis addon library for Allegro
version 1.3.7
alogg is a library which makes it easier to use Ogg/Vorbis streams with Allegro. It offers facilities to decode, stream, and encode Ogg/Vorbis streams with thread support and experimental URL streaming, and integrates those facilities with Allegro's datafile and sample loading routines.
alogg's homepage can be found at http://lyrian.obnix.com/alogg/
-- Dependencies
alogg requires the following:
libogg-1.0rc3 (or newer, available at http://www.vorbis.com/) libvorbis-1.0rc3 (or newer, available at http://www.vorbis.com/) allegro-4.0.0 (or newer, available at http://alleg.sf.net/)
To compile with Tremor, a fixed point implementation of the Ogg/Vorbis decoder, you also a copy of the Tremor library. Tremor can be found at http://www.xiph.org/.
To compile with URL support, you also need libcurl 7.10 or newer. libcurl is a library for transferring data specified with URL syntax, available at http://curl.haxx.se/. Note that URL streaming is experimental is not ready for production use yet. In particular, I have not yet tried to stream off an Icecast server.
To compile with threaded streaming support, you also need pthreads. pthreads is the most widely used library for thread support, and is supplied with most operating systems. You can even get a version of pthreads for MS-DOS and MS-Windows. For the latter, it can be found somewhere at http://www.redhat.com.
For information on how to build alogg and use it in your programs, have a look in the INSTALL file, or the alogg documentation.
