  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • FFMPEG "no such file or directory" on Android

    25 mars 2013, par 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 :
