  • 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.

  • Compile FFmpeg with librtmp ERROR : librtmp not found

    10 juin 2014, par 谢小进

    Environment : Mac OS X 10.9.2, Xcode 5.1.

    I have compiled librtmp, libogg and libspeex successfully, they are in the directories named fat-librtmp, fat-libogg and fat-libspeex , then I run the shell script as below to coompile them into FFmpeg :

    Unluckily, the config.log shows :

    check_pkg_config librtmp librtmp/rtmp.h RTMP_Socket
    
pkg-config --exists --print-errors librtmp
    
Package librtmp was not found in the pkg-config search path.
    
Perhaps you should add the directory containing `librtmp.pc'
    
to the PKG_CONFIG_PATH environment variable
    
No package 'librtmp' found
    
ERROR: librtmp not found

    I have googled and knew that configure contains a line enabled librtmp  && require_pkg_config librtmp librtmp/rtmp.h RTMP_Socket, which maybe be wrong. Right ? Can somebody help me to solve it ?

    UPDATE at 2014/06/10

    I think it’s about pkgconfig or something, so I have create a file named librtmp.pc at /usr/local/lib/pkgconfig, which contains below text :

    prefix=/usr/local/librtmp
    
exec_prefix=${prefix}
    
libdir=${prefix}/lib
    
includedir=${prefix}/include
    

    
Name: librtmp
    
Description: RTMP implementation
    
Version: v2.3
    
Requires:
    
URL: http://rtmpdump.mplayerhq.hu
    
Libs: -L${libdir} -lrtmp -lz
    
Cflags: -I${includedir}

    Also I have moved built librtmp to /usr/local. After above being done, I run the shell script again, but still same error ! Can somebody told me why and how to solve it ?
