    VDPAU- Should I try it?

    I have read about the new VDPAU support, and am wondering if I should try it. http://zacgarrett.com/software/insta...pau/index.html gives a fairly involved way to do this. http://www.avenard.org/files/mythtv-vdpau/ says I can simply install a new repository, then upgrade the system. Have other mythbuntu users tried either of these? I am interested in peoples experiences and opinions.

    If I did try this and it didn't work, how would I recover?

    Re: VDPAU- Should I try it?

    If you have a card supporting VDPAU and you wish to watch 1080p conent, I would say it is a must. I'm building a AMD X2 5600+ (dual core 2.9Ghz) HTPC for a mate with a Asus M3N78-VM motherboard which has the Nvidia 8200 IGP. Watching a high quality 1080p/DTS bluray rip used to consume 90%+ of the CPU and result in servere video stutter and audio sync issues. After installing the 180.22 drivers and compiling the VDPAU enabled Mplayer CPU usage dropped to around 15%, and the related stutter and sync issues disappeared. Some people say that if you have a fast enough CPU then VDPAU doesn't matter, however I haven't found that to always be the case.

    If you follow the first guide at the top of this thread, then there is nothing to recover as you run the VDPAU enabled Mplayer in parrallel with the standard version.

    As always backup before you do any major changes.

    My frontend boots from a small (8Gb) CF card in a CF-SATA adapter. Before I make any major changes I boot up in rescue mode, go to the command prompt and then copy the Boot CF to a backup CF card (Plugged into an USB card reader). The command I use to copy the entire CF is:-

    dd if=/dev/sda of=/dev/sdb bs=4k

    A backup takes about 15-20minutes, but thats alot less than reinstalling everything if an update goes wrong

    The flash memory thing sounds complicated. I recall hearing about a way to back up the mythtv database- which would probably be enough.
    Also I would be interested hearing which method people used for installing vduap and what problems they ran into.

    Hi,

    I imagine that I'll try out the http://www.avenard.org/files/mythtv-vdpau/ depository sometime this week. I just need to steal a vdpau compatible vga card from another PC and install it in the frontend.

    Re: VDPAU- Should I try it?

    Hi,

    Finally got a 9400gt from the childrens box

    I'll be trying it out this evening/tomorrow. Is it really as easy as adding the http://www.avenard.org/files/mythtv-vdpau/ repositries and doing an apt-get update/upgrade?

    I'll post my findings here in the next few days.

    I'm also curiosu to know the results. I'm lookign at building a mythbuntu box around the gigabyte GA-E7AUM-DS2H.

    This makes it sound like all you'd have to do is install the latest nvida driver and add the repositries!
