    <p>I'm trying to build FFMPEG library for my android application using the NDK. I have downloaded the source code from it's website and I think I build it (it's my first try working with NDK and ffmpeg). I have created a <code>build.sh</code> file which I'm using to execute it from command line on Mac OS X. But I have a few questions...</p> <p>First things is as I know I need Android.mk file so I can use the builded library in my application,but I don't know how to do that for reasons which I told you above. After I run my <code>build.sh</code> I get <code>android</code> folder with a few folders and some libraries. So my first question is, how can I build the Android.mk file which I need...and maybe if someone can explain me why I need it.</p> <p><img src="https://i.stack.imgur.com/3LTM1.png" alt="enter image description here"></p> <p>My second question is I need some libraries from ffmpeg to be able to use them from my app, but after the build i can't see them in my source tree. I know that I have to enable them in my <code>build.sh</code> and I think I did,but I can't see them. So any kind of information about my build file will be helpful for me to understand how to configure it. Here is how it looks like :</p> <pre><code> #!/bin/bash ###################################################### # Usage: # put this script in top of FFmpeg source tree # ./build_android # It generates binary for following architectures: # ARMv6 # ARMv6+VFP # ARMv7+VFPv3-d16 (Tegra2) # ARMv7+Neon (Cortex-A8) # Customizing: # 1. Feel free to change ./configure parameters for more features # 2. To adapt other ARM variants # set $CPU and $OPTIMIZE_CFLAGS # call build_one ###################################################### NDK=~/Desktop/android-ndk-r5b PLATFORM=$NDK/platforms/android-8/arch-arm/ PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86 function build_one { ./configure \ --target-os=darwin \ --prefix=$PREFIX \ --enable-cross-compile \ --extra-libs="-lgcc" \ --arch=arm \ --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \ --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \ --nm=$PREBUILT/bin/arm-linux-androideabi-nm \ --sysroot=$PLATFORM \ --extra-cflags=" -O3 -fpic -DANDROID -DHAVE_SYS_UIO_H=1 -Dipv6mr_interface=ipv6mr_ifindex -fasm -Wno-psabi -fno-short-enums -fno-strict-aliasing -finline-limit=300 $OPTIMIZE_CFLAGS " \ --disable-doc \ --disable-ffmpeg \ --disable-ffplay \ --disable-ffserver \ --disable-ffprobe \ --extra-ldflags="-Wl,-rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -nostdlib -lc -lm -ldl -llog" \ --enable-zlib \ --enable-version3 \ --enable-nonfree \ --enable-libmp3lame \ --enable-libspeex \ --enable-libtheora \ --enable-libfaac \ --enable-libvorbis \ --enable-libaacplus \ --prefix=$DIST_DIR \ $ADDITIONAL_CONFIGURE_FLAG make clean make -j4 install $PREBUILT/bin/arm-linux-androideabi-ar d libavcodec/libavcodec.a inverse.o $PREBUILT/bin/arm-linux-androideabi-ld -rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -soname libffmpeg.so -shared -nostdlib -z,noexecstack -Bsymbolic --whole-archive --no-undefined -o $PREFIX/libffmpeg.so libavcodec/libavcodec.a libavformat/libavformat.a libavutil/libavutil.a libswscale/libswscale.a -lc -lm -lz -ldl -llog --warn-once --dynamic-linker=/system/bin/linker $PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/libgcc.a } #arm v6 #CPU=armv6 #OPTIMIZE_CFLAGS="-marm -march=$CPU" #PREFIX=./android/$CPU #ADDITIONAL_CONFIGURE_FLAG= #build_one #arm v7vfpv3 CPU=armv7-a OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=vfpv3-d16 -marm -march=$CPU " PREFIX=./android/$CPU ADDITIONAL_CONFIGURE_FLAG= build_one #arm v7vfp #CPU=armv7-a #OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=vfp -marm -march=$CPU " #PREFIX=./android/$CPU-vfp #ADDITIONAL_CONFIGURE_FLAG= #build_one #arm v7n #CPU=armv7-a #OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=neon -marm -march=$CPU -mtune=cortex-a8" #PREFIX=./android/$CPU #ADDITIONAL_CONFIGURE_FLAG=--enable-neon #build_one #arm v6+vfp #CPU=armv6 #OPTIMIZE_CFLAGS="-DCMP_HAVE_VFP -mfloat-abi=softfp -mfpu=vfp -marm -march=$CPU" #PREFIX=./android/${CPU}_vfp #ADDITIONAL_CONFIGURE_FLAG= #build_one </code></pre> <p>Thanks for any kind of useful information/suggestions/examples and etc.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
