  • 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) (...)

  • 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.

  • FFMPEG (libx264) "height not divisible by 2"

    16 mai 2017, par Andy Hin

    I am trying to encode a .mp4 video from a set of frames using FFMPEG using the libx264 codec.

    This is the command I am running :

    /usr/local/bin/ffmpeg -r 24 -i frame_%05d.jpg -vcodec libx264 -y -an video.mp4

    I sometimes get the following error :

    [libx264 @ 0xa3b85a0] height not divisible by 2 (520x369)

    After searching around a bit it seems that the issue has something to do with the scaling algorithm and can be fixed by adding a -vf argument.

    However, in my case I don’t want to do any scaling. Ideally, I want to keep the dimensions exactly the same as the frames. Any advice ? Is there some sort of aspect ratio that h264 enforces ?

  • FFMPEG Without Headers is Causing Video To Be Height 0X0

    21 novembre 2022, par Devin Dixon

    I am grabbing a stream from X11 and streaming it to other sources like Node Media Server and Twitch. Except, I get audio only with no video and the resolution size says 0X0.

    


    My ffmpeg is command is this :

    


     /usr/bin/ffmpeg -hide_banner -hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128 -video_size 1920x1080 -y -v info -f x11grab -draw_mouse 0 -r 60 -s 1920x1080 -thread_queue_size 14000 -i :0.0+0,0 -f alsa -thread_queue_size 14000 -i plug:bsnoop -acodec aac -strict -2 -ar 44100 -b:a 128k -af aresample=async=1 -c:v h264_vaapi -vf format=nv12,hwupload,scale_vaapi=w=1920:h=1080 -attempt_recovery 1 -max_recovery_attempts 2 -drop_pkts_on_overflow 1 -video_size 1920x1080 -crf 19 -preset medium -maxrate 14000k -bufsize 14000k -r 60 -crf 25 -g 120 -tune zerolatency -f flv rtmp://[some_other_source]

    I've noticed there are several errors the headers going out. For VAAPI, how do I set resolution header ?
