    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?

  • Compile FFMPEG + x264 - undefined references

    6 février 2019, par tishu

    I have been trying to find a solution online for a couple of days with no luck. I am using Ubuntu and trying to compile the latest FFMPEG stable version (1.0.1) with x264 support. I made sure I uninstalled any existing x264 then I downloaded the latest x264 source and compiled it with the following config :

    ./configure --prefix=$PREFIX \
    
    --enable-shared \
    
    --enable-static \
    
    --disable-gpac \
    
    --extra-cflags=" -I$ARM_INC -fPIC -DANDROID -fpic -mthumb-interwork -ffunction-sections -funwind-tables -fno-short-enums -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__ -Wno-psabi -march=armv5te -msoft-float -mthumb -Os -fomit-frame-pointer -fno-strict-aliasing -finline-limit=64 -DANDROID -Wa,--noexecstack -MMD -MP " \

    --cross-prefix=${ARM_PRE}- \
    
    --disable-asm \
    
    --host=arm-linux \
    

    
    make clean
    
    make install

    All goes well, and I checked the installed version :

    x264 -V
    
    x264 0.129.x

    configuration: --bit-depth=8 --chroma-format=all
    
    x264 license: GPL version 2 or later

    I then try to compile FFMPEG with the following options :

    The configure and make clean/make install work well, but when I try to create the .so file the following command fails :

  • How to compile FFmpeg for Android with clang in ubuntu18.04 ?

    I wonder how to do it with clang friendly.I’m still new int the NDK and I’ve just started learning.So I have no idea to do it at all.

GNU assembler not found, install/update gas-preprocessor

    it seems like that the frist char was ignored. When I try :

    /home/gjy/ndk/android-ndk-r16b-linux-x86_64/android-ndk-r16b/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-as -fPIC -c -o /tmp/ffconf.jHtqLsFE/test.o /tmp/ffconf.jHtqLsFE/test.S
    
invalid option -- P

    can any body help fine the problem？
