  • 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.
    The code of this (...)

  • dnxhddec : decode and use interlace mb flag

    dnxhddec : decode and use interlace mb flag

    This bit is 1 in some samples, and seems to coincide with interlaced
    
mbs and CID1260. 2008 specs do not know about it, and maintain qscale
    
is 11 bits. This looks oversized, but may help larger bitdepths.
    

    Currently, it leads to an obviously incorrect qscale value, meaning
    
its syntax is shifted by 1. However, reading 11 bits also leads to
    
obviously incorrect decoding : qscale seems to be 10 bits.
    

    However, as most profiles still have 11bits qscale, the feature is
    
restricted to the CID1260 profile.
    

    The encoder writes 12 bits of syntax, last and first bits always 0,
    
which is now somewhat inconsistent with the decoder, but ends up with
    
the same effect (progressive + reserved bit).
    

    Partially fixes ticket #4876.
