  • 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.

  • Access to macroblocks and motion values with libx264

    6 mars 2019, par Enock

    I have a question and I hope someone can help me.
    I want to extract all motion vectors in P_type mocroblock in a P_frame during encoding
    h264 video with libx264 (x264). libx264 uses X264Context in the function x264_frame to encode
    video. Then, I want to know how can I access to macroblocks in a picture and
    how to access to motion vectors table on this picture while using the X264Context struct.
    With MpegEncContext we can access them while using MpegEncContext struct’s mb_type, *mvs[2], mb_width, mb_height and mb_stride. But I don’t know how to have such informations (
    mb_type, *mvs[2], mb_width, mb_height and mb_stride) with X264Context struct.

    Please I need your help.

    Regards

  • lavu/opt : distinguish between native and foreign access for AVOption fields

    lavu/opt : distinguish between native and foreign access for AVOption fields

    Native access is from the code that declared the options, foreign access
    
is from code that is using the options. Forbid foreign access to
    
AVOption.offset/default_val, for which there is no good reason, and
    
which should allow us more freedom in extending their semantics in a
    
compatible way.
