  • Support audio et vidéo HTML5

    10 April 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.

  • De l’upload à la vidéo finale [version standalone]

    31 January 2010, by

    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 (...)

  • FFMPEG "no such file or directory" on Android

    25 March 2013, by Feras

    I am trying to use the ffmpeg binary and call it via a native linux command in android. Most of the commands work fine but the problem is that when i need to pass an http url as an input to the -i option i get "No such file or directory" for the url. The url however is existing and running the SAME command on a mac does the job as expected.

    Here is my compile config for the ffmpeg build:

    ./configure \
    $DEBUG_FLAG \
    --arch=arm \
    --cpu=cortex-a8 \
    --target-os=linux \
    --enable-runtime-cpudetect \
    --prefix=$prefix \
    --enable-pic \
    --disable-shared \
    --enable-static \
    --cross-prefix=$NDK_TOOLCHAIN_BASE/bin/$NDK_ABI-linux-androideabi- \
    --sysroot="$NDK_SYSROOT" \
    --extra-cflags="-I../x264 -mfloat-abi=softfp -mfpu=neon" \
    --extra-ldflags="-L../x264" \
    \
    --enable-version3 \
    --enable-gpl \
    \
    --disable-doc \
    --enable-yasm \
    \
    --enable-decoders \
    --enable-nonfree \
    --enable-encoders \
    --enable-muxers \
    --enable-demuxers \
    --enable-parsers \
    --enable-protocols \
    --enable-protocol=http \
    --enable-filters \
    --enable-avresample \
    \
    --disable-indevs \
    --enable-indev=lavfi \
    \
    --enable-hwaccels \
    \
    --enable-ffmpeg \
    --enable-ffplay \
    --enable-libmp3lame \
    --enable-network \
    \
    --enable-libx264 \
    --enable-libfaac \
    --enable-zlib

    Its based off of this project: https://github.com/guardianproject/android-ffmpeg-java

    Command is something along the lines of that:

    ffmpeg -i "http://someurl" -f mp3 -ab 192000 -vn demoo.mp3

    The idea being to download the audio track from a video and encode it as mp3. I explicitly added multiple enable protocols options but nothing seems to do the job. I tried an alternative config as well, removing everything below enable-gpl just to make sure there arent any conflicts, but it fires the same error. If i give it a normal filesystem path it works fine.

    Following the comments here is the exact output of the command and the output:
