  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Format ffmpeg command to extract the full klv for an mpg/ts file

    24 décembre 2020, par Andrew Marquez

    I am extracting the KLV data from an mpg file using klvdata and ffmpeg.

    



    Following the readme, I have downloaded the sample "Day Flight.mpg" video file that contains KLV data. Running the quick start command works (I get the exact same result as the readme example for the first 6 frames.)

    



    However, for the life of me I don't know how I can extract the KLV data for the entire video file.

    



    As an experiment, I tried creating the KLV data file from an offset start :

    



    ffmpeg -ss 5 -i Day\ Flight.mpg -map data-re -codec copy -f data - > out.klv


    



    and when I run it through my code with different start times (5, 25, etc.) I do get different results.

    



    This (to me) would suggest that the mpg file does contain KLV data throughout, but I can only access 6 frames at a time.

    



    I would expect to be able to run an ffmpeg command to output the full KLV data. I need help formatting my ffmpeg command to properly provide all the data.

    



    To replicate, download the "Day Flight.mpg" file from the klvdata project page and run the command I posted above. You will note it is less than a page long. It should be many, many pages long. Thank you for your help !
