  • 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.

  • 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.
