Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

NGINX RTMP convert flv to hls ?
3 mai 2016, par MandelDuckI have a server that takes an rtmp stream and saves it as flv.
Web users can view the flv video in their browser, however iPhone users can’t as it is flash
Is there away to convert the saved flv files on the fly to hls for the iPhone viewers ?
here is my config, Webusers access the vod application
rtmp {
server {
listen 1935;
chunk_size 4096;
application live {
live on;
record all;
record_path /videos/av;
idle_streams off;
}
application audio {
live on;
record audio;
record_path /videos/audio;
idle_streams off;
}
application vod {
play /videos/av;

MinGW 64 - CMake Error - CMake will not be able to correctly generate this project. (Windows11 - ffmpeg - AudioToolboxWrapper)
22 janvier 2024, par corruptsmurfI occasionally encode some audio, and I am trying to modify my install of ffmpeg using the code and instructions from the following Github repo :
https://github.com/dantmnf/AudioToolboxWrapper


Instructions from the above Github page :


# in MSYS2 MinGW shell
cd path/to/this/repo
mkdir build
cd build
prefix="$PWD/install-prefix"
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$prefix" ..
make install

# test if we can use the wrapper library, it should not crash
./testapp

mkdir ffmpeg
cd ffmpeg
export CFLAGS="-I${prefix}/include" LDFLAGS="-L${prefix}/lib"
path/to/ffmpeg/source/tree/configure --enable-audiotoolbox
make LD="${prefix}/bin/atw_ldwrapper"

# test if ffmpeg can use it
./ffmpeg -f lavfi -i sine=1000 -c aac_at -f mp4 -y NUL


My OS is Windows 11 Pro 64-bit, Version 10.0.22621 Build 22621


The example on that git mentions using MSYS2 MinGW, which I didn't have, so I did the following :


- 

- Created a folder at C :/01Code/ATW for this project.
- Installed MSYS2 MINGW64 using installer from https://github.com/msys2/msys2-installer/releases
- Began to run through the commands from AudioToolboxWrapper
- Ran into issues running the command
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$prefix" .. - As part of troubleshooting, I did the following :












pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-gdb
pacman -S mingw-w64-x86_64-cmake
pacman -S gcc
pacman -S gdb
pacman -S cmake
pacman -S make


- 

- I updated the PATH environment variable to include the msys path (C :\msys64\usr\bin)
- I opened CMD as admin and executed
C:\msys64\mingw64\bin>mklink make mingw32-make.exeto create a symbolic link for make (recommended by another forum post).
Honestly, I cannot remember how many pacman commands I ran trying to find the correct dependency.






So here is what happens :


cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$prefix" ..

The command generates some output, but I am assuming it is incomplete. If I try the next command, I get this :

undefined reference to 'memset' while configuring ffmpeg
20 mai 2013, par Jacques GiraudelI want to port ffmpeg on android to use it in an app (to convert video files in webm format).
I use the following command to configure FFMPEG :
./configure --target-os=linux \
--cross-prefix=arm-linux-androideabi \
--arch=arm-linux \
--sysroot=$TC_SYSROOT \
--nm=$NM \
--ar=$AR \
--cc=$CC \
--ld=$LD \
--disable-symver \
--enable-small \
--enable-libvorbis \
--enable-libvpx \
--extra-cflags="-I$PROJECT_BASE/jni/libvorbis/build/include -I$PROJECT_BASE/jni/libogg/build/include -I$PROJECT_BASE/jni/libvpx/libvpx -I$PROJECT_BASE/jni/libvpx/libvpx/build/install/include" \
--extra-ldflags="-L$PROJECT_BASE/jni/libvorbis/build/lib -L$PROJECT_BASE/jni/libogg/build/lib -L$PROJECT_BASE/jni/libvpx/libvpx/build/install/lib" \
--prefix=$PROJECT_BASE/jni/ffmpeg/buildI use a standalone toolchain (NDK compiler version : 4.6). I dont use the AS of the toolchain, when I try the command block (I have waited for 10 minutes without response, some starting infos in the config.log and it seems to block at the beginning of the compilation). The different lib and directory added are the build install of the libraries needed (ogg, vorbis and vpx).
I obtain this message :
/Bureau/TripApp/jni/ffmpeg /Bureau/TripApp/jni /Bureau/TripApp/jni

ERROR: libvpx decoder version must be >=0.9.1I have also a warning at the beginning of the file :
WARNING: arm-linux-androideabipkg-config not found, library detection may fail.And many other errors which seem to be not blocking (eg : related to the support of older ARM version than the targeted one)
libvpx is configured using the following command (the make succeeds) :
./libvpx/configure --target=armv5te-android-gcc --disable-examples \
--sdk-path=$NDK_BASE --prefix=$PROJECT_BASE/jni/libvpx/libvpx/buildThe NDK version used is r8e.
My search on this :
The libvpx version used is 1.1.0, memset is a function defined in string.h. String.h is present in the include dir of the sysroot used (and memset is defined).Do you see what could be the source of the problem ?
