Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...) -
Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

FFmpeg Android compilation : command not found
18 février 2019, par maxestSo I’m trying to build, on Ubuntu, FFmpeg from sources. Here’s a script I assembled from here and there :
#!/bin/bash
NDK=$HOME/Desktop/adt/android-ndk-r19b
SYSROOT=$NDK/platforms/android-26/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64
function build_one
{
./configure
--prefix=$PREFIX
--arch=arm
--target-os=linux
--enable-cross-compile
--cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi-
--sysroot=$SYSROOT
--extra-cflags="-Os -fpic $ADDI_CFLAGS"
--extra-ldflags="$ADDI_LDFLAGS"
$ADDITIONAL_CONFIGURE_FLAG
make clean
make -j9
make install
}
CPU=arm
PREFIX=$(pwd)/android/$CPU
ADDI_CFLAGS="-marm"
build_oneUnfortunately I get a list of following outputs :
ffbuild/config.sh is unchanged

./build_android_2.sh: line 34: --extra-ldflags=: command not foundI’ve double checked all the paths are correct. Although I create by hand folder
/home/maxest/Desktop/adt/android-ndk-r19b/sources/ffmpeg-4.1/android/arm
because there were no folderandroid/arm

I'm trying to make the zoom video using image but facing


TypeError: must be real number, not NoneType.



It used was to run but I don't remember if I might have updated numpy, ffmpeg, or any thing else that is now causing the error. I have tried the code on python 3.10 and 3.11 and get the same error in both. I was previously running it on python 3.10.
