Multicore x264 not working

[Rio6000]

first ofall thx for this great app! it's really unmissable

but i'm having trouble with the multicore stuff...

when i'm in the 'common transcode settings' tab it says its using 4 cores, but in the MEncoder tab the "enhanced multicore support for h264 HD content" is greyd out.
also when i'm transcoding and streaming to my ps3 i only see 1 core beeing used.

I've also tried to recompile mplayer but no effect, I couldnt find anything in ./configure --help which resembles activating it.
i'm on Archlinux 64bit.

i hope someone can help me!

Here are a method for enabling MT support in mplayer/mencoder.

But I'm not sure that is enough to enable that greyed out part in the GUI.

will try it, i hope there is a more clean way of doing it
i like my Arch clean and mean:P

no succes...

i've downloaded the mplayer source package through abs and downloaded the ffmpeg-mt through git, copied the libav folders and let makepkg compile it.

after that i put this in the expert settings dialogue:

vcodec == h264 :: -mt -lavdopts fast : threads=4

still it's not using all four cores.

any ideas?

if you have recompiled mencoder and done a "make install", I guess standard mencoder binary should be multithreaded... so there's nothing to do on PMS side (just select the good number of cores)

Have you verified in the debug-log file that the options are used in the mencoder call ? Could you post it here, not all but a least the part where mencoder is called.

I can confirm a succesfull compile of mencoder multithreaded on Ubuntu and indead just in PMS set the core option to the amount of cores you have.
I see multiple cores doing their work 1080p works as advertised!!

Could you please help me with the parameters you chose ? I tried to compile the latest svn together with the ffmpeg-mt libs as mentioned above and the mencoder that results from this does not work with PMS. I mean compilations goes nicely if I run mencoder like this it seems to work but from PMS it always give me corrupted streams message on my PS3 (and no visible errors in PMS ??)

Thanks for your help ! (I am also on Ubuntu 8.04 server 64bits)

Check this, viewtopic.php?f=3&t=315 perhaps you should pre install all dev libs.
I had to do it to get mencoder working fine without "data corrupted".
Bye.

I have install and test Ubuntu 8.10 server 64bits, and use the same way than on 32bits install and mencoder compil and work fine.
