  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Revision 8d7f53f04c : Account for rate error in GF group Q calculation. When GF group adaptive maxQ i

     Modify /vp9/vp9_cx_iface.c



    Account for rate error in GF group Q calculation.

    When GF group adaptive maxQ is enabled this patch accounts
    somewhat for accumulated error in the rate control.

    This improves accuracy quite a bit on many clips especially
    when there is overshoot.

    Examples when the overshoot and undershoot command line
    parameters are set to 100 :

    Hall @ 1200 overshoot is reduced from 67-24%.
    Akiyo @ 400 undershoot is reduced from 28%-15%.

    Setting a lower value for undershoot or overshoot still
    reduces the error further.

    Impact on metrics is mixed with some gains in average psnr
    but generally a little lower (e.g. 0.5%) on overall and ssim.

    The GF group adaptation is still off by default in this patch.
    Compared to with the head, enabling this mode now gives
    big average psnr gains on the YT sets (e.g. YT_HD >11.2%),
    a drop in overall PSNR (YT-HD 3.9%) and a smaller drop or
    neutral for SSIM.
