Rowe, Ketan Patel, and Brian Smith Amiga: Michael Balzer Internet: balzer@heike.informatik.uni-dortmund.de DESCRIPTION This is the third release of the first public domain MPEG viewer for the Commodore Amiga. MPEG stands for Moving Pictures Experts Group and is also the name for a method of compressing video streams. The compression is lossy and CPU hungry, but quite efficient. MPEG movies are not really 24 bit, but YUV. As an example on the efficiency, take the iicm.mpg anim and convert it to a *256* color IFF anim - the 1.7 MB MPEG stream will result in a 6.3 MB IFF file. Now do the same conversion for 24 bit... I'm sad to say there is no PD MPEG _encoder_ available up to now, but maybe there will be. For further questions on MPEG please first read the FAQ I included into the bin archive. The player is capable of displaying standard MPEG animations either in a window on Workbench or on its own custom screen. It can save each frame of the anim to disk, so you can build an IFF format animation from an MPEG file. The MkAnim tool (by John Bickers) to assemble the frames is included. Changes against V1.22 (second release): * Release 1.23 (not released due to 2.01): * - Dither mono & threshold now work (fast!) * - New option: -saveiff framename_%d.iff (guess for what ;-) * Saving currently forces screen mode. No support for 24 bit yet * - Added new option: -amiga screen:mode/depth/width/height, * reworked option dependancies * * Release 2.01 (Feb 12 1993): * - Based upon the new 2.0 release of the mpeg player for UNIX * - No need to enhance color allocation, as the new player * allows to set the range values (ncolors = l_rng*cr_rng*cb_rng) * - 24 Bit IFF save mode implemented REQUIREMENTS AmigaOS 2.04 or later + at least 68020 and 68881. AmigaOS 3.0 recommended. 68040 recommended. Free memory of about 2 MB should be sufficient. It may even work with 1 MB, but I haven't tested that. SPECIAL REQUIREMENTS This player needs Markus Wild's ixemul.library. As this lib still doesn't seem to exist on everyone's machines, I have included it with the distribution. For the complete GCC distribution contact your next FTP server. And... NO, THIS PLAYER DOESN'T NEED X-WINDOWS! FTP LOCATIONS There are two archives, one containing the binaries (and other usefull stuff) and the other one containing the sources (split up into original UNIX part plus special Amiga changes & extensions). I included the necessary X11 header files (don't think, many Amiga programmers have them around). The Makefile and code are for Markus Wild's port of the famous GNU GCC C compiler (thanks again, Markus!). Don't forget to build an amiga.lib version 39.x for your GCC before trying to compile the code.
