  • Complie FFMpeg with Xcode5 preview's clang

    2 août 2013, par Yeung

    With release of IOS7 beta, I would like to try compiling ffmpeg for ios7.

    There is a lots answer like this. It use the llvm-gcc as compiler.

    However, seem like Xcode 5 would not include llvm-gcc. Then I have no choice but to use clang to compile.

    I use the following to config :

    export IOS_SDK="/Applications/Xcode5-DP4.app/Contents/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk"
    

    
./configure $CONFIG_DISABLE_FLAG $CONFIG_ENABLE_FLAG \
    
--arch=arm \
    
--target-os=darwin \
    
--cc=/Applications/Xcode5-DP4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang \
    
--as='gas-preprocessor.pl /Applications/Xcode5-DP4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang' \
    
--ar=/Applications/Xcode5-DP4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar  \
    
--sysroot=$IOS_SDK \
    
--cpu=cortex-a8 \
    
--extra-cflags="-arch armv7 -mfpu=neon -mfloat-abi=softfp -ftree-vectorize -ffast-math -funsafe-math-optimizations -fsingle-precision-constant -isysroot ${IOS_SDK} -I${IOS_SDK}/usr/include" \
    
--extra-ldflags="-arch armv7 -mfpu=neon -mfloat-abi=softfp -ftree-vectorize -ffast-math -funsafe-math-optimizations -fsingle-precision-constant -isysroot ${IOS_SDK} -L${IOS_SDK}/usr/lib" \
    
--enable-pic

    clang would probably not take CFLAGS other than -arch  -isysroot -I into account, but let it be.

    I seems it can complie but I encounter this. Actually, I don't understand the answer in this question. Using the external assembler ? Yes, the toolchains do have a assembler stated it is GNU version 1.38. Using --as=/Application/Xcode5-DP4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/as, it even cannot pass the check as test. It fall back to use 'gas-preprocessor.pl $CC'

    Here is the config log to cannot pass :

    Yep, with config --disable-asm would complie but it probably not a option.

  • How to specify a non default type when calling a FFmpeg library using ctypes

    1er août 2013, par Jim Ramberg

    I am calling an FFMPEG library called avformat_alloc_context() that returns a pointer to type AVFormatContext. The structure AVFormatContext is defined in the avformat library.

    Obviously ; this is not one ctypes default types and results in an error when I try to pass a reference to it to another ffmpeg library further down in my code.

    Is there a way to add in the the classes defined inside of the library ? I read through what documentation I could find online and was not able to find a good answer to this question.

  • FFMPEG build on eclipse - 2 structs of the same name overlapping on a build

    30 juillet 2013, par ApolloKing

    I am currently working on the libav api provided by FFMPEG, and I have successfully compiled and installed FFMPEG onto my OS (Via ./configure, make, make install) Now I want to run it on Eclipse, so I imported the latest ffmpeg build and tried to build it (with ./configure).

    I built ffmpeg, but there are two structs overlapping one another. ffmpeg.h contains a struct outputstream while another file in the libavfolder called smoothstreamingenc.h contains another struct of the same name : outputstream.

    The question is, what must be done to resolve this without messing up the ffmpeg build ?
