On hardened desktop clementine and subtitleeditor play nothing until: paxctl -m /usr/libexec/gstreamer-0.10/gst-plugin-scanner /usr/bin/clementine /usr/bin/subtitleeditor If you mark only gst-plugin-scanner, both clementine and subtitleeditor will crash.

I do not have any problem with mplayer2.
Disabling USE orc in make.conf and updating solved my problem, clementine works fine after rebuilding media-libs/gst-plugins-base and media-libs/gst-plugins-good. subtitleeditor also works fine now. Please rename USE 'orc' to 'jit', because orc is jit, from homepage: "Orc is a just-in-time compiler implemented as a library...". Masking or pax marking dev-lang/orc is required for hardened profile. orc is not optional for: media-libs/schroedinger net-wireless/gnuradio
Fixed in gstreamer-0.10.36, which is masked for the moment.
Why 'paxctl -m' is used when orc is disabled?
(In reply to comment #6) > Why 'paxctl -m' is used when orc is disabled? There is no way for media-libs/gstreamer to know whether or not you will in the future install some gst-* package that has orc enabled. Since for many users the answer would be "yes", and since disabling memory protection on gst-plugin-scanner is unlikely to have security implications, always using 'paxctl -m' seems to be a reasonable approach.
Have masked the orc use flag in the hardened profile. Undo the paxctl -m thing on Remerge the needed things.
(In reply to comment #8) > Have masked the orc use flag in the hardened profile. I do not understand why you are treating orc differently from jit. Hardened already has "-jit -orc" in USE in make.defaults, but jit is not in the hardened use.mask - so why did you decide to add orc to use.mask? > Undo the paxctl -m thing I've added an orc USE flag to media-libs/gstreamer-0.10.36; paxctl -m is now run only when USE=orc. This allows those hardened users who need orc for non-laggy video playback, or who use gst-plugins-schroedinger, to enable it by unmasking the flag. I hope that this solution is satisfactory to the hardened team.

Thinking through all the scenerios a user may switch between here, they should be okay. So yeah, looks good to me.
I was about to close this bug since gstreamer 0.10.36 and 1.0.3 have conditional pax marking on gst-plugin-scanner but the use flag is masked while jit is not, is that normal ?
Not sure.
Have unmask orc and added it do the Hardened FAQ. so close the bug if it is nothing else.
(In reply to comment #13) > Have unmask orc and added it do the Hardened FAQ. > so close the bug if it is nothing else. That's all. Thanks for the update.
