    Cool Getting VDPAU working through 14.04

    Hi,

    Because 14.04 is so new, I think the instructions on getting VDPAU though UVD working, can somebody please help?

    I have 14.04 installed and a HD6450.

    Now my 14.04 should have a suitable kernel and mesa 10, so what is left to do, I see references to having to put a firmware blob for my 6450 somewhere?

    I wan't better performance, quality and de-interlacing in mythtv, that needs VDPAU as far as I can tell.

    Thanks for looking!

    Cheers
    Richard

    Default Digging around.

    Most of the stuff I need seems to be on here but:

    $ sudo vdpauinfo
    display: :0 screen: 0
    Failed to open VDPAU backend libvdpau_r600.so: cannot open shared object file: No such file or directory
    Error creating VDPAU device: 1

    I read that libvdpau_r600.so is in libg3dvl-mesa, no sign of that on my system, do i have to install this, any other steps?

    That's only in a ppa from oibaf. I used that packagename for a mesa upgrade for debian as well, but i dont think it will be the final name. with my evergreen card i have got mpeg2 issues however.

    libg3dvl-mesa is a package only from my PPA, which currently only provides packages for 13.10. I'll plan to provide packages for 14.04 when it will be officially released.

    Oibaf: Will not be a part of the 14.04 release automatically?

    I always sent useful patches from my PPA to Debian or mesa. Some get merged, other still not. A couple of year ago I also sent VDPAU support to Debian (see here) but it's still not included. If/when it will be included in Debian it should also appear on Ubuntu.

    Do you know how to disable mpeg2 support from radeon vdpau? Maybe at least for the shader implementaion and not for the hardware variant.

    Default You can run this PPA on 14.04, no issues right now

    I have had no problems with this PPA or with PPAs in general on 14.04. I treat Ubuntu as a rolling release, and PPAs I update only when they too support the new release. Synaptic will choose the newer of the PPA or Ubuntu version, usually that will be the PPA one. Occasionally a newer-versioned Uubntu package will come out that is incompatable, I roll these back and pin them until the PPA catches up. Had to do that with xorg-edgers once, when Ubunty versions with early Mir suppport didn't work and had to be rolled back.

    Needless to say, this sort of mixing requires that you know what you are doing-and that you fish downloaded packages out of /var/cache/apt/archives and save them in some organized way so rollback versions can always be found. I've done this for many years now with few more issues than the ones that come up with alpha releases anyway.

    I've had VDPAU support on my systems and used it on system images running on single-core machines to play 1080p video since it first became available for radeon, at first using a Red Hat package as a tarball to extract to get the necessary libraries before libg3dvl-mesa was packaged as a .deb anywhere I knew of. Worked fine all the way back to the first DRM-next kernel to support it, with just one bug then and now: 1080p AVCHD files from my camera usually play just fine, but occasionally crash the GPU so a reboot is needed to get OpenGL running again. This never happens with mp4 files containing normal H264 streams, there is something almost but not properly supported in the files my camera makes. Nvidia's blog and cards won't support those files at all, while Radeon with VDPAU plays them most of the time on every r600/Evergreen card I've tested. Normal H264 playback is fantastic, even on a 2300MHZ AMD Athlon 64 single core.

    Reported the bug? You could try to cut such a clip to one second, then play it on loop to get a crash; if so, upload that small file.

    I guess you could also just download and install that .deb file, the libg3dvl-mesa package.
