  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • Static Compilation of FFmpeg with x264 support

    17 février 2014, par b1izzard

    Based on the Tutorial, I tried to build the latest FFmpeg binary with x264 support for Command line execution using Android-ndk-r9c.

    I had built the x264 using the below script :

     #!/bin/bash        
    

    

    
PREBUILT=/home/blizzard/bin/android-ndk-r9c/toolchains/arm-linux-androideabi-4.6/prebuilt
    
                PLATFORM=/home/blizzard/bin/android-ndk-r9c/platforms/android-9/arch-arm
    
                PREFIX=/home/blizzard/bin/android-ndk-r9c/sources/ffmpeg
    

    

    
            ./configure --prefix=$PREFIX \

            --sysroot=$PLATFORM
    

    
            make
    
            sudo make install
    
            sudo ldconfig

    For building FFmpeg I had used the below script :

     #!/bin/bash                    
    
              PLATFORM=/home/blizzard/bin/android-ndk-r9c/platforms/android-9/arch-arm

    Can anybody help me in building the latest version of FFmpeg or Can you share the latest FFMpeg binary for Android ?

  • no c compiler found libx264 build [closed]

    24 août 2012, par kerim yucel

    I have been trying to build ffmpeg for Android and I have managed to do so by using roman10's tutorial.

    However, I needed x264 and I enabled libx264 in the configurations but it wasn't able to find the library. A quick internet search led me to the answer that I have to build x264 seperately and include it to ffmpeg config by editing ExternalLibs flags.

    Currently I am using this script to build x264. Everything is fine except the fact that the error saying "No working C compiler is found" pops up. I have updated and installed build-essential and my gcc version is up to date.

    Any help will be appreciated. Thanks a lot.

    P.S. I am using ndk 4 just to make everything compatible with the tutorial link given above. I am running Ubuntu with VirtualBox from Windows 7.

    Edit : I have been trying this tutorial as well, I am getting the same error along with unknown options error for each configuration options.

    Another edit :
    I have tried this code and obtained the following.

    echo 'int main() return 0 ;' > main.c && arm-eabi-gcc main.c || echo $ ?

    /home/mehmet/Android_NDK_r4/build/prebuilt/linux-x86/arm-eabi-4.4.0/bin/../lib/gcc/arm-eabi/4.4.0/../../../../arm-eabi/bin/ld : crt0.o : No such file : No such file or directory collect2 : ld returned
    1 exit status 1

    I have checked the flags as well, flags seem ok or I can't see the faulty line. Above you may find the build script I am using.

    Problem solved. It was just a mistake related to typos. It works well now.

  • no c compiler found libx264 build [closed]

    24 août 2012, par kerim yucel

    I have been trying to build ffmpeg for Android and I have managed to do so by using roman10's tutorial.

    However, I needed x264 and I enabled libx264 in the configurations but it wasn't able to find the library. A quick internet search led me to the answer that I have to build x264 seperately and include it to ffmpeg config by editing ExternalLibs flags.

    Currently I am using this script to build x264. Everything is fine except the fact that the error saying "No working C compiler is found" pops up. I have updated and installed build-essential and my gcc version is up to date.

    Any help will be appreciated. Thanks a lot.

    P.S. I am using ndk 4 just to make everything compatible with the tutorial link given above. I am running Ubuntu with VirtualBox from Windows 7.

    Edit : I have been trying this tutorial as well, I am getting the same error along with unknown options error for each configuration options.

    Another edit :
    I have tried this code and obtained the following.

    echo 'int main() return 0 ;' > main.c && arm-eabi-gcc main.c || echo $ ?

    /home/mehmet/Android_NDK_r4/build/prebuilt/linux-x86/arm-eabi-4.4.0/bin/../lib/gcc/arm-eabi/4.4.0/../../../../arm-eabi/bin/ld : crt0.o : No such file : No such file or directory collect2 : ld returned
    1 exit status 1

    I have checked the flags as well, flags seem ok or I can't see the faulty line. Above you may find the build script I am using.
