    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 ?

  • Compiling ffmpeg for IOS (R_ABS reloc error)

    14 septembre 2024, par Oliver Hume

    I've been trying to compile the ffmpeg libraries for IOS. I can get it to work if I use —disable-asm, but for performance I'd like to build with them enabled.

    



    This is one of many configure commands I've used.

    



    ./configure --prefix=armv7 --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avresample --enable-cross-compile --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc" --extra-cflags="-arch armv7 -miphoneos-version-min=5.0" --extra-ldflags="-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk -miphoneos-version-min=6.0" --arch=arm --cpu=cortex-a9 --disable-everything --enable-pic --enable-static --disable-shared

    



    It compiles fine, but when I try to link against it in my project I get :

    



    ld : in /ffmpeg/libavcodec/libavcodec.a(simple_idct_armv5te.o), in section _TEXT,_text reloc 0 : R_ABS reloc but no absolute symbol at target address for architecture armv7

    



    Am I missing some key option ? I've tried using the 1.0 build and the latest git version of ffmpeg.

  • AVFrame / AVPicture change color component

    26 avril 2014, par RoeeL

    Given a video stream (runs with SDL), I need to somehow make the video’s frames color green only, blue only and red only (depends on input).

    How can I do that ? How can I set the color component to be RED only for instance ? (R = 255, G = 0, B = 0)

    Didn’t manage to find anything on google. would love to get some assistance.

    thanks
