  • MediaSPIP en mode privé (Intranet)

    17 septembre 2013, par

    À partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
    Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
    Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...)

  • C api on capturing video stream from webcam using ffmpeg

    14 juillet 2013, par Tanjim Hossain Sifat

    I am a new user of ffmpeg. Ffmpeg has a good documentation on using it in command-line, but i am looking for some C API code.

    I want to make a software using C, that would capture video stream from webcam and give me the video stream in raw format, that I would encode in a codec later.

    I have visited this given link, but it provided only the command-line use, not the use of libraries provided by ffmpeg :
    http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20capture%20a%20webcam%20input

    I also visited this link, which gave me good idea on using the libavcodec, but no other tutorial is available :
    ffmpeg C API documentation/tutorial

    Please someone help me finding C api on video stream capturing from webcam using ffmpeg's library. Thanks in advance.

  • error = "sh : /root/bin/ffmpeg : Permission denied

    6 août 2015, par user1503606

    Ffmpeg install location.

    Hi All i am running Centos 6.6 and i installed ffmpeg using this guide following each step.

    http://trac.ffmpeg.org/wiki/CompilationGuide/Centos

    But when i try and run.

    $output = shell_exec("cd {$targetDir} && /root/bin/ffmpeg -i {$fileName} {$wav} 2>&1");

    I get

    sh : /root/bin/ffmpeg : Permission denied

    After reading through lots of post i believe i should not have installed ffmpeg in /root/bin/

    How do i install it in say /usr/local/bin ?

    I ran this.

    PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure
    —prefix="$HOME/ffmpeg_build" —extra-cflags="-I$HOME/ffmpeg_build/include" —extra-ldflags="-L$HOME/ffmpeg_build/lib" —bindir="$HOME/bin" —pkg-config-flags="—static" —enable-gpl —enable-nonfree —enable-libfdk-aac —enable-libfreetype —enable-libmp3lame —enable-libopus —enable-libvorbis —enable-libvpx —enable-libx264 —enable-libx265

    Can someone let me know who i would do this thanks.

  • Unrecognized options even though compiled FFmpeg on Ubuntu manually

    11 février 2016, par Kathy Lee

    I would like to convert a video from .avi to .mp4 with same quality using ffmpeg but the command I put in the terminal always report some errors saying that there are unrecognized options.

    I have compiled the ffmpeg manually following the steps in http://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

    After compiling the ffmpeg, I used the command below the compress the video

    ffmpeg -i input.avi -c:v libx264 -crf 19 -preset slow -c:a libfaac -b:a 192k -ac 2 output.mp4

    But the error message is saying "Unrecognized option ’crf’" :

    ffmpeg version 2.8.5 Copyright (c) 2000-2016 the FFmpeg developers

    Then I tried to omit flag -crf, but I got error saying

    Then I omitted flag -preset, it says I do not have libx264....

    [mjpeg @ 0x164f2c0] Changeing bps to 8

Unknown encoder 'libx264'

    I am very confused what is going on because I have complied ffmpeg step by step and also installed the dependencies such as libx264 as described in http://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu. The command I used to configure ffmpeg is

     ./configure   --prefix="$HOME/ffmpeg_build"   --pkg-config-flags="--static"   --extra-cflags="-I$HOME/ffmpeg_build/include"   --extra-ldflags="-L$HOME/ffmpeg_build/lib"   --bindir="$HOME/bin"   --enable-gpl   --enable-libass   --enable-libfdk-aac   --enable-libfreetype   --enable-libmp3lame   --enable-libopus   --enable-libtheora   --enable-libvorbis   --enable-libvpx   --enable-libx264   --enable-nonfree

    Why these errors happen ? How can I fix them to allow me to convert the video from .avi to .mp4 ?

    Thank you very much !
