I stumbled onto a pure delphi mpeg encoder: http://www.msbsoftware.it/mpegpas/ But i need a decoder - no activex or com stuff if i can avoid it.

It only works for Mpeg1/2 and only for the m2v part (so only video, no multiplexed streams or sound streams). The article describes all the steps: reading the mpeg bitstream, huffmann decoding, idct conversion (including MMX optimisation!), YUV to RGB, I, B and P frame assembly. I bought a CD once with all the DI articles of 3 years or something, for something like $50. Maybe they still have this offer.

The Delphi Magazine had a multipart article by Erik van Bilsen on this topic, starting in issue 82 (June 2002). Search the article database on http://www.thedelphimagazine.com. The articles will probably not be available online but you can download the source code archives for them. -- Peter Below (TeamB) Use the newsgroup archives : http://www.mers.com/searchsite.html http://www.tamaracka.com/search.htm http://groups.google.com http://www.prolix.be Back to top subi Guest Posted: Fri Mar 04, 2005 4:56 am    Post subject: Re: native mpeg decoding & rendering The Source archives are available and the archive names are as follows dmag82.zip dmag83.zip dmag84.zip dmag85.zip dmag87.zip dmag88.zip Subi Back to top Jon Lennart Aasenden Guest Posted: Mon Mar 07, 2005 5:04 pm    Post subject: Re: native mpeg decoding & rendering Thanks guys! I have a native mp3 decoder with the huffman stuff.. maybe i can add the sound bit (with some experimentation). Ill post the source as always if i ever get it done.
