    Interesting is anyone successfully tested it?

    For me it's not work with this error in "/tmp/streaming_client.log":
    Code:
    Fri Aug 22 01:25:51 2014 UTC - CVAAPIAccel: vaInitialize() failed: unknown libva error
    My vainfo output:
    Code:
    libva info: VA-API version 0.35.1
    libva info: va_getDriverName() returns 0
    libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
    libva info: Found init function __vaDriverInit_0_35
    libva info: va_openDriver() returns 0
    vainfo: VA-API version: 0.35 (libva 1.3.1)
    vainfo: Driver version: Intel i965 driver for Intel(R) Haswell Desktop - 1.3.2
    vainfo: Supported profile and entrypoints
          VAProfileMPEG2Simple            : VAEntrypointVLD
          VAProfileMPEG2Simple            : VAEntrypointEncSlice
          VAProfileMPEG2Main              : VAEntrypointVLD
          VAProfileMPEG2Main              : VAEntrypointEncSlice
          VAProfileH264ConstrainedBaseline: VAEntrypointVLD
          VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice
          VAProfileH264Main               : VAEntrypointVLD
          VAProfileH264Main               : VAEntrypointEncSlice
          VAProfileH264High               : VAEntrypointVLD
          VAProfileH264High               : VAEntrypointEncSlice
          VAProfileVC1Simple              : VAEntrypointVLD
          VAProfileVC1Main                : VAEntrypointVLD
          VAProfileVC1Advanced            : VAEntrypointVLD
          VAProfileNone                   : VAEntrypointVideoProc
          VAProfileJPEGBaseline           : VAEntrypointVLD
    So now I just wonder is it only require 1.3.2 driver or also libva 1.3.1 too?

    PS: Using Kubuntu 14.04 with Oibaf PPA.

    Oh dumb me, it's all because I forgot to install 32-bit packages and Steam didn't suggest to install them.
    So after I installed "libva1:i386 libva-drm1:i386 libva-glx1:i386" it's now working:
    Code:
    Fri Aug 22 02:11:56 2014 UTC - VAAPI hardware decoding
    Now display latency decreased from 80ms to 30ms.

    What streaming clients are supported by Steam?

    Any chance one could use Limelight with it?

    It's only work with other Steam clients for now. In future somebody have to reverse engineer it.
