    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) (...)

  • Supporting all media types

    13 avril 2011, par

  • Conversion for WebM file format using FFMPEG

    23 mars 2012, par user974435

    I am using followng command to convert video to webm format

    ffmpeg -i video/ds2.mp4 -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b:a 345k -s 640x360 video/ds2.webm

    I am receiving following errors :

    1) incompatible sample format 's16' for codec 'libvorbis'

    2) strptime() unavailable on this system, cannot convert the data string

    Do you any idea why I cannot convert, tested conversion to FLV and it's working very well

    Console output

    C:\inetpub\wwwroot>ffmpeg -i video/testavi.avi video/ds2.webm

  • ffmpeg on fb0 from Nexus Galaxy error : "could not get frame filename number 2"

    I use ffmpeg to convert fb0 files from Androids and produce screenshots. For some reason this does not work with the Nexus Galaxy.

    I get this error :

  • Why does FFMPEG always make large WebM files ?

    2 avril 2013, par Student of Hogwarts

    I'm trying to encode my movies into WebM :

    ffmpeg -i input.MOV -codec:v libvpx -quality good -cpu-used 0 -b:v 10k
    
-qmin 10 -qmax 42 -maxrate 10k -bufsize 20k -threads 8 -vf scale=-1:1080
    
-codec:a libvorbis -b:a 192k
    
output.webm

    I want to encode at a couple of different bit rates (video and audio combined) :

    • 2192 kbps
    • 1692 kbps
    • 1000 kbps

    The problem is that no matter which bit rates I enter, I always get a file with a bit rate higher than 1900 kbps. (1914 kbps with the code example above.)

    What am I doing wrong ?
