On the stable is the issue with the fix as it was not revbumped. So if you had mpg123 emerged prior the fix you still have the issue. @hardened: Open stablereq for latest mpg123 and problem will be solved (i don't want the bugspam so you do it). Closing the bug as CANTFIX as there is nothing on mplayer2 side we could do. mpg123 is not the only problem: with -vo xv mplayer2 works fine, but with -vo vdpau it works only after paxctl -m. Error message: MPlayer interrupted by signal 11 in module: preinit_libvo dmesg: grsec: denied RWX mmap of <anonymous mapping> by /usr/bin/mplayer2[mplayer:10758] uid/euid:1000/1000 gid/egid:1000/1000, parent /usr/local/bin/vf[vf:10757] uid/euid:1000/1000 gid/egid:1000/1000 vdpau support is mesa based, i have nouveau drivers. Seems the problem is similar to other GL application. 'mplayer2 -vo vdpau' works fine with ati foss driver and mesa-9, nouveau problem is in bug #432520 |
