This is a port of Opus 1.3.1 to MSDOS/DJGPP. Opus is a codec for interactive speech and audio transmission over the Internet. Opus can handle a wide range of interactive audio applications, including Voice over IP, videoconferencing, in-game chat, and even remote live music performances. It can scale from low bit-rate narrowband speech to very high quality stereo music. Opus is specified by IETF RFC 6716: https://tools.ietf.org/html/rfc6716 The Opus format and this implementation of it are subject to the royalty- free patent and copyright licenses specified in the file COPYING. DJGPP specific changes. ======================= - The port does not support being compiled with assembler optimized code. This also means that both, the SSE support and the run-time CPU detection have been disabled. If this support is wanted, then the user has to port it alone and make the required adjustments for his particular sound hardware. - The reading/writing stream is switched into O_BINARY mode. If the stream is connected to stdin/stdout/TTY, then Ctrl-C and Ctrl-Break are re-enabled so the user can interrupt the program. - Apart from those changes there are no other user visible ones. Only some small changes have been done to get the library configured and compiled. - The html formatted documentation has been generated on a linux machine using Doxygen and is not SFN clean. - Opus does not provide any test suit so the port cannot be tested except by using it. - To configure and compile this port at least the following version of Bash and Make are required: http://ftp.delorie.com/pub/djgpp/current/v2gnu/bsh4253b.zip http://ftp.delorie.com/pub/djgpp/current/v2gnu/mak43br2.zip No previous versions will work nor are supported. Any future version should work. - The port has been configured and compiled on WinXP SP3, Win98SE and MSDOS 6.22 with DOSLFN v0.41f. There is no guarantee that this may be possible with any other DOS-like OS. Due to the use of long file names it will not be possible to configure and compile without LFN support. The port has been compiled using gcc346 and bnu2351b. As usual, all djgpp specific files (diffs, README files, etc.) are stored in the "djgpp" directory. The sources have been configured to be build in the "0build" directory. If for some reason it does not work for you, delete its contents and configure from scratch again. Please read the docs to become familiar with this product. Here is an extract of the ChangeLog file showing the user visible changes from the last port (Opus 0.0.0) to this one: ------------------------------------------------------------------------------- This is the first port. Read the documentation. ------------------------------------------------------------------------------- The port consists of the usual two packages that have been produced using djdev20X (CVS repository code) and can be downloaded from ftp.delorie.com and mirrors as (time stamp 2022-10-17): Opus 1.3.1 headers, library and man format documentation: http://ftp.delorie.com/pub/djgpp/current/v2tk/lops131b.zip Opus 1.3.1 source: http://ftp.delorie.com/pub/djgpp/current/v2tk/lops131s.zip Send Opus specific bug reports to <opus AT xiph DOT org>. Send suggestions and bug reports concerning the DJGPP port to comp.os.msdos.djgpp or <djgpp AT delorie DOT com>. Enjoy. Guerrero, Juan Manuel <juan DOT guerrero AT gmx DOT de>
