    Phoronix: Ubuntu Will Not Enable Open-Source VDPAU Support

    This morning I wrote about Mesa 10.1 likely going into Ubuntu 14.04 LTS, but if you were hoping this means Ubuntu will enable VDPAU driver support for open-source hardware-accelerated video decoding, that improvement to video playback isn't going to happen with the official Ubuntu Mesa/Gallium3D driver packages...

    Yeah, exactly.
    What I meant is, VLC (< 2.2?) doesn't seem to use VDPAU at all, and you can check that simply by looking at cpu usage. The debugging output when using the -v flag is almost cryptic... but you can see there that it isn't using VDPAU.
    Anyway, VLC itself seems to be buggy as hell. mpv is great.
    VLC requires the latest and greatest LIBAV packages and the Ubuntu repos are way out of date on that and I've read that VLC has to be compiled a specific way to enable VDPAU, which distros like Ubuntu aren't doing. Hence VLC and VDPAU don't really work at this point for most users who can't figure out all the mess. I've also read that installing the latest LIBAV packages isn't necessarily a work-around as they don't get recognized by the software in many cases.

    It still misses xvmc however. Also there is no reference to any of the 3 bug reports about it in the changelog.

    Hi folks, I was wrong, VLC in Ubuntu 13.10 indeed doesn't utilize vdpau. For some reason I had to set it's video output manually to glx-whatever, after I had replaced the standard xorg/mesa-stack with oibaf's stuff. Yesterday (with current oibaf stack) I could remove that option and it still works fine. I doesn't seem to use vdpau in any case and also it's not an output option. Sorry for the confusion.

    What I wrote is still valid for xine though.

    how can reducing of write calls hurt a ssd?

    And even if it would be true, still the advantage in speed rocks. And even if you dont use a ssd this advantage is even bigger.
