HELP: MPEG-1 player in pure Assembler
Hello Amiganer !
At time i try to programming a MPEG-1 decoder / player for the 68060 CPU in pure Assembler. So far I have not found the correct instructions on the construction of the MPEG-1 format. Has anyone here perhaps a tutorial about the header structure of MPEG-1 or any assembler routines on this topic? At Aminet site, I have this program with source code and some assembler routines found. http://aminet.net/package/gfx/show/aMiPEG_1.1_src Now you can see a "discrete cosine transformation" is needed for MPEG-1 decoding. Thanks for your help greets, Victim |

Shame that RiVA development is over and the product has not been open sourced / made free. I wonder if the author makes any money from it? The successor for OS4.0 seems to be recently active (1 year) http://dvplayer.amigarevolution.com/ Last edited by alexh; 06 April 2009 at 13:01. |

This is a good page for description of the MPEG headers I have a lot on google search, but most documents on mpeg are absolutely incompleteThis link is only for MPEG audio and not for the video format for the intended Quote:

Besides Riva is there any good free mpeg players for the amiga ?
mpeg2 more than mpeg1, mpeg2 being the standard dvd format. |

There was Frogger.
http://frogger.rules.pl/ You're never going to be able to playback 720x576i MPEG2 with a 68k Amiga. AFAIR anything below an 060 struggles to do 352x288 MPEG1 (Hence CD32 FMV cart). You're gonna need a PPC and a gfx card with YUV frame buffer support. |
