    Ok, i could not test any other driver between 260.19.12 (13th oct) and 260.19.21 (5th nov). This issue seems to be fixed in a short test. If you like you can try it with 1 gb ram (you can restrict ram via option) and 128 mb vram. It still works, but vlc will most likely never work on atom for full hd vc1 (thats what i tested). Definitely too high system load. So i can use mplayer for content where i do not need subtitles and xbmc whre i need em. It's a bit sad because vlc has got even a parser for the bluray structure, you do not need to play the m2ts you can directly play the mountpoint of the bluray (you can do funny things with vbox and play original bluray with that when you export em...). when vlc is used in that way then the time shown is correct (xbmc has a got approximation, mplayer/vlc not). also you can select the audio/subs with the name not the id. Really bad that the best player for it is too slow with atom cpu.

      I believe xbmc also has this capability now if it is compiled with libbluray.

        Alright guys, so i bought gt 430.
        vdpau is awesome. H.264 L4.1 works great on linux.

        i just wondering, why the CPU usage still high ? Like about 50% and more.
        i use mplayer with ffmpeg multithreading.

          You dont use vdpau correctly. Put
          Code:
          vc=ffh264vdpau,ffmpeg12vdpau,ffvc1vdpau,ffwmv3vdpau,ffodivxvdpau,
          in your .mplayer/config.

            You're right. now it works.
            But, if i play 1080p movie with 15mbps bitrate, the CPU usage still hit about 50%. Although i use ffmpeg-mt, the load seems doesn't spread among the threads.
            I encounter this message too :
            [h264_vdpau @ 0x8a4b8c0]Cannot parallelize deblocking type 1, decoding such frames in sequential order

              There must be something wrong. Do you really use

              vo=vdpau

              normally that's default, but you can add it too. Btw. i would use the unpatched mplayer, works best with vdpau - especially more easy to play 3gp with audio without messing around with ffmpeg-mt options.

                got this error also
                [vdpau] Error when calling vdp_presentation_queue_block_until_surface_idle: A catch-all error, used when no other error code applies.

                I am gonna try unpatched mplayer version now.

                  I tried unpatched version. Still, sometimes the CPU goes fluctuated over 10% according to the video load.
                  Seems like multithreading ffmpeg doesn't work with vdpau.

                    That's normal especially when you cpu is clocking down dynamically. But 50% load would be too much. As the gpu decodes you don't need multithreading anyway.

                      Yeah, i wonder why.

                        Maybe think about it, when your cpu is clocked 1 ghz or below then 10% is different than when it runs at 3 ghz.

                          nope, not a diff. Either i set it dynamically, or if i just boost the core to the highest clock. Still, at some scene, the load can read 30-50%.

                            I have just heard about the Powermizer, luckily perhaps. I am amazed by the possibilities. It enables GPU to run with lowest clocks without using the graphic cords, a fully functional desktop with 3 D effects can be activated with compiz. The battery will also last longer by using it. It can be installed by editing the Xorg configuration file. If you want GPU intense game, it will not work well. Btw, Powermizer 7.0 Mobile technology has a number of mobile power management as well. Should try it.

                              Recent mobile Nvidia gpu (Nvidia laptops) doesn't work anymore as the Optimus features aren't supported. So, who cares about the powermizers or whatever they are since the laptop won't work properly anyway.

                              So, previous post is a fail (is that how you say it? ;-) I am not up on the net lingo.

                                Im not using nvidia because of zero opensource, but I do look around. And the optimus issue from what I read is really heavy. Not that nvidia care at all outside of the corporate policy - especially from my (this) post.

                                I think part of the problem lays within either X not supporting active switch between two cards; or (or additinally) very possibly this optimus thing is very proprietary/patented - similar to CSS/HDCP useless crap. I don't like it, it does not prevent piracy, it rises issues from legal owners, it lowers buyers rights, leads to "intellectual property" failure heavily manipulating science and technology in the future.

                                Both intel, amd and nvidia support it, do it regardless - I ignore it (don't buy) as whole. The world rotates further.

                                In modern world words "exclusive", "limited", "patented" or "only for", not only related to software, hardware or IT technology; but as whole - sound(or made to sound) like an advantage. To me, they sound like heavy limitation, negative quality, negative factor.

                                As if I would be talking loud on the streets "Hey, I have my myopia" and everyone around would cry happily "Wow! Thats very exclusive!! Im jealous! I want to have it too! I will pay big money for it!"

                                Linux may be very very limited and sometimes bad in several parts, many (hardware, software etc) companies publish binary blobs, or provide only minimal opensource effort, or completely ignore it - and contribute. And I can easily buy windows and install it and have it instantly here and things etc - no problem. But it would taste as peace of sh** in big nice cup of "shut the f*ck up". I just cannot drink THAT.

                                Ah whatever, Im too much offtopic. Sorry for too much nothing in this thread.
