  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Building FFMPEG library for iOS6.0 ARMv7 Processor

    15 août 2013, par Jimmy

    WARNING :

    I was just informed by another user that there are some legal issues revolving around using FFMPEG for iOS, leaving the link here http://multinc.com/2009/08/24/compatibility-between-the-iphone-app-store-and-the-lgpl/

    I cleaned up my question a little bit, when I wrote it the first time I was flustered. Now I can be more clear after taking a small break.

    Edit : learned that you have to build for ARMv7, ARMv7s and iOS6.0

    I'm trying to use the FFMPEG library in an XCode 4.5.1 project. And I'm trying to build it for ARMv7. What I'm looking for is the exact process, and some explanation. I understand that this is not a well documented problem. But I know that other pople have had the same problem as me.

    What I have been able to do.

    I have been able to build the library for testing.

    1) I have been able to clone ffmpeg. For beginners this will get you started by creating a directory with the ffmpeg source. (Kudos to the guys who wrote it)

    git clone git ://source.ffmpeg.org/ffmpeg.git ffmpeg

    2) I have been able to write a config file that doesn't have any errors. We will go back to this part later. This is the command I attach to ./configure

    ./configure
    —disable-doc
    —disable-ffmpeg
    —disable-ffplay
    —disable-ffserver
    —enable-cross-compile
    —arch=arm
    —target-os=darwin
    —cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2

    —as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2'

    —sysroot=/applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk

    —cpu=cortex-a8
    —extra-ldflags='-arch=armv7 -isysroot /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk'
    —enable-pic —disable-bzlib —disable-gpl —disable-shared —enable-static —disable-mmx —disable-debug —disable-neon —extra-cflags='-pipe -Os -gdwarf-2 -isysroot /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk
    -m$thumb_opt :-no-thumb -mthumb-interwork'

    These are some things to note.

    • I had to download ( https://github.com/yuvi/gas-preprocessor ) copy the file gas-preprocessor.pl at /usr/local/bin. Set permissions to read write (777)
    • Make sure I'm using the right GCC compiler : /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2
    • Make sure I'm using the right SDK : /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk
    • —extra-cflags="-arch armv7" causes : error : unrecognized command line option “-arch”

    Here in lies the problem.

    I can include the library like so

    libavcodec/avcodec.h

    But when I started to write the encoder. I received this warning, and countless errors.

    ignoring file /Users/Jimmy/Development/source.ffmpeg/Library/libavutil.a, file was built for archive which is not the architecture being linked (armv7s) : /Users/Jimmy/Development/source.ffmpeg/Library/libavutil.a

    That means that I didn't build the right binary.

    What I'm looking for is someone whose done it before, to walk all of us through the process of building FFMPEG for iOS6.0 and ARMv7 and the majority of things to look out for. Thanks a ton.

  • FFMPEG/avconv option -c:a copy

    1er juin 2013, par b747fp

    I am converting a bunch of videos from FLV to MP4 (for iphone compatibility) and using AAC codec it kept throwing out "invalid audio bitrate" or similar errors. I tried "-c:a copy" option and it works, but I am wondering if that tells ffmpeg to use the original MP3 codec or just the original audio bitrates/frequencies ?

    /usr/bin/avconv -i /var/www/vhosts/domain.com/httpdocs/conversions/34649274.flv -s 640x480 -b 1248k -vcodec libx264 -acodec aac -strict experimental -c:a copy /var/www/vhosts/domain.com/httpdocs/conversions/34649274.mp4
  • Build libaacplus 2.0.2 for ios

    23 mai 2013, par Javan

    Does anyone build libaacplus2.0.2(Download here) successed for iOS ? I want ffmpeg support that.It cast me one day to build that, but failed.

    This is libaacplus2.0.2/autogen.sh, It was edited, just let it create configure file :

    #!/bin/sh
    # Run this to set up the build system: configure, makefiles, etc.
    # (based on the version in enlightenment's cvs)

    package="libaacplus"

    }

    if test "$DIE" -eq 1; then
       exit 1
    fi

    if test -z "$*"; then
       echo "I am going to run ./configure with no arguments - if you wish "

    After run the autogen.sh script :
