  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • x264 options for colorprim

    25 septembre 2018, par Kumar Swaminathan

    I have a source with the following color characteristics (as determined by ffprobe using "ffprobe -v error -show_format -show_streams source") colormatrix=smpte170m:colorprim=reserved:transfer=reserved.

    I would like to preserve this and so I encoded with ffmpeg with libx264 by specifying the following x264 specific options :

    "-vcodec libx264 -profile:v baseline -level 3.1 -b:v 2400k -preset medium -x264opts ref=3:keyint=90:colormatrix=smpte170m:colorprim=reserved:transfer=reserved -r 30000/1001"

    But now I get an error =>

    [libx264 @ 0x2234820] bad value for ’colorprim’ : ’reserved’

    Error initializing output stream 0:1 — Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    What should the ideal mapping here be to preserve the input color characteristics ?
