When manufacturers realized that people would soon run out of address space with the old intel 32-bit architecture (which Debian called ia32), both intel and AMD designed new instruction sets. Intel designed the Itanium, a completely new machine architecture. This is the architecture that Debian calls ia64. It is completely incompatible with ia32. AMD designed what Debian calls AMD64, a 64-bit architecture that's very similar to the old ia32, except that a lot of places where ia32 had 32-bit registers, addresses, or data paths, AMD64 had 64-bit regiters, address, and data paths instead. THe result was also incompatibility, except for one thing -- because 32-bit Windows systems were still dominant on the market, AMD designed a special compatibility mode, in which only 32 bits of all those things were used, and it was completely conpattible with the old 32-bit ia32 systems. The result was a system that was ready for the 64-bit future, and could still run all the old 32-bit software, including the old 32-bit operating systems, though you don't get the full advantages of the new architecture. I'm told that 64-bit Windows will still run old 32-bit programs by putting the machine in 32-bit mode when running them. (anybody know for sure?) Linux. now that multiarch is well on its way to realisation, can also do this witth a 64-bit kernel if 32-bit libraries are installed. There's no copatibility in the opposite direction. 64-bit code just will not run in 32-bit mode, and that's all the old ia32 cpu's have. You could of course run emulation software on the ole machines, but you'd probably lose and order of magnitude in speed. -- hendrik > > > On 23 June 2014 10:15, Jer <[email protected]> wrote: > > > On 14-06-19 08:41 PM, Denis-André Desjardins. wrote: > > > >> I tried to run a video with movie player, and this is what happenedè > >> "Could not find GStreamer caps mapping for FFmpeg codec 'h264', and you > >> are using an external libavcodec.
