Amiga comes through! ffmpeg to the rescue

[Piru]

Don't use Linux much, but would like to, so I can't comment on what is available for it.

Everything you could ever dream of, including the said ffmpeg.

So really ffmpeg comes through, not any platform in particular.

PS. ffmpeg is available for every platform you can think of, including Windows.

My favorite however is gentoo. This system allows you to compile and build the WHOLE system. It too has a package manager that automatically installs packages, but they have to be compiled. It does take longer, but the best part about gentoo is the packages are new (not unstable, not moldy) and compiled explicitly for your system. I think it most captures the amiga model of putting the user back in control of his system. You choose what goes in! But, it is more difficult to set up for a beginning user.
