SELinux has x264 use flag disabled?

I'm trying to create a media server, but I am not able to build any packages with the x264 use flag. Just wondering why it is disabled in the profile? I have tested building x264 on my system, which is amd64, and it did not come up with any errors or anything.

I need to be able to transcode videos on the fly so they will play on my Xbox 360, and I have several videos which are mkv format and don't want to always spend time transcoding videos just to play on Xbox.

Did you try enable it in /etc/make.conf?

I am using profile 'default/linux/amd64/2008.0/desktop' and it is also not enable by default.

I believe profiles, depending on build type like general, desktop, server, etc, only enable minimal set of USE flags by default. User will have to enable other flags base on individual needs.

PS: the package ufed is a very good and up to date USE flag editor to manage make.conf USE flag.

I think it is disabled (not beeing able to use it at all) under SElinux. No idea however why.

Code: Select all

$ cat /etc/portage/package.use
media-video/ffmpeg a52 aac amr imlib mp3 theora vorbis x264 xvid
media-video/ffmpeg encode

Code: Select all

$ emerge -pv ffmpeg

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] media-video/ffmpeg-0.4.9_p20080326  USE="a52 aac amr encode imlib mmx mp3 theora threads vorbis xvid zlib -X (-altivec) -bindist -debug -doc -hardcoded-tables -ieee1394 -ipv6 -network -sdl -test -truetype (-x264)" 0 kB

I know that x264 is in the package.use.mask for the amd64 profiles, I'm just wondering why it is when a build of x264 works without any issues. I need x264 support enabled with ffmpeg so I can use the transcoding features of fuppes.

It is not only under SELinux, but under any amd64 (and would assume ia64) profiles as well. It seems odd that it would be blocked, and no reason that I can see in any of the files explain why it is masked.

I am using amd64 desktop profile. It is not disable in the profile, but not enable either.

I am using amd64 2008.0 desktop profile and i can (and have) enable x264 support in ffmpeg.

My mistake. I had thought all 64 bit versions had it masked. Seems to only affect SELinux Hardened profiles.

Anyone have any ideas as to why the use flag is masked for SELinux?

x264 is disabled in all profiles, and then enabled by overriding it in x86, amd64 and ppc arch profiles. what does `eselect profile show` say?

Code: Select all

# eselect profile show
Current make.profile symlink:
  /usr/portage/profiles/selinux/2007.0/amd64/hardened

Why would it not be enabled in the SELinux profiles then?

You have to comment the line with "x264" at file /usr/portage/profiles/selinux/use.mask, and x264 flag will be enabled.
I did it, and it works for me without problems.

Looks like you stumbled on a bug here.

To enable it you should add "-x264" (yes, that's a hyphen, I know it is counterintuitive) to /etc/portage/profile/package.use.mask (meaning that you will disable/override the mask this way).

cord: Note that /usr/portage/profiles/ will get overwritten by your next sync.

Will this be fixed anytime soon so that the change can be permanent?
