After emerging ffmpeg I don't have any man pages for it, not sure why or what info you'd need but here's the emerge info

Probably can get rid of some of those USE flags, I always find new reasons to add more

Hi,

It doesn't seem like there are any man pages in that package. However, if you look in /usr/share/doc/ffmpeg-<version> there's a number of documentation files. If you have gentoolkit installed, you can run "equery files <package>" to see all the files installed by a package, which is how I found this information.

I see thanks for that (I'm still getting the grasp of equery)
Those should help with some things, I wonder why there is no man page?

Becuase some developers think that man is obsolete and info is the way to go (though they've been thinking that for quite some years now, and man doesn't seem like dying yet

).

Code: Select all

$ info ffmpeg

Try re-emerging it with the doc flag set:

Code: Select all

USE="doc" emerge ffmpeg

Yah, another USE flag

info would be good if there was a ffmpeg info page

man might be 'dead' but it's easy simple and quick, why stop using what works?

Thanks justincataldo, that's what I needed since apparently RTFMing is an antique practice and isn't included in packages by default anymore these days...

Yeah, I can see one if I type info ffmpeg in command line. That's why I suggested it. At least, in the version I use (0.4.9_p20070129), there is an info page installed on my system.

True, don't worry, it will not die

And I love man pages as well.

Ya, I didn't get a man page until I used the 'doc' flag, this also built the info page which wasn't there either...-doc really means no docs

/me adds doc to his USE list

I wouldnt put doc in your global use flags, since it often pulls in dependencies (doxygen comes to mind), will download extra stuff, and other exciting things.

I'd use it on a per-package basis if you find that you need it.
