Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

FFMPEG Video Multiplexer
4 décembre 2015, par NaderI am a DirectShow developer, I used to build multiplexers that take 2 video inputs and generate one output, I would then use a video encoder mux to feed it the output + anothrr audio stream to generate the final video output. The multiplexer (DirectShow framework) allows me to process the input video from two sources (for example, adding effects using the two frames).
Does anyone know how this can be done using FFMPEG, or at least point me to the right resources ? Thanks -
Why my ffmpeg libs are so large ? [on hold]
9 avril 2014, par user3504221I compiled ffmpeg libs on my Ubuntu 64-bits using the following script :
mkdir ~/ffmpeg_sources
#x264
cd ~/ffmpeg_sources
wget http://download.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
tar xjvf last_x264.tar.bz2
cd x264-snapshot*
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static --disable-asm
make
make install
make distclean#FFmpeg
cd ~/ffmpeg_sources
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig"
export PKG_CONFIG_PATH
./configure --prefix="$HOME/ffmpeg_build" --extra-cflags="-I$HOME/ffmpeg_build/include" \
--extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" --extra-libs="-ldl" -- enable-gpl \
--enable-libx264 --enable-x11grab --disable-yasm
make
make install
make distclean
hash -rBut the final libs are really large (For example, libavcodec.a > 140 Mb). Anybody know why my libs are so large ?
EDIT
My Solutions :
- add the option "—disable-debug" to the ./configure. The size of my libavcodec fell from 150Mb to 12Mb !
- Remove all unnecessary codecs : Add the options -disable-encoders, —disable-decoders and then add only codecs you want with —enable-encoder=NAME and —enable-decoder=NAME. Print the list using ./configure —list-encoders —list-decoders. see ./configure —help for more information. (My final libavcodec has a size of 4Mo)
