我看过很多关于 FFmpeg 和在 Android 中使用 FFmpeg 的帖子，但我发现这些帖子中的大部分都是针对旧版本的 FFmpeg 或 Android NDK。我能够从 https://github.com/mconf/android-ffmpeg 得到结果，其中包括文件:“libavcodec.so”、“libavformat.so”、“libavutil.so”、“libswscale.so”。但是，仅仅将这些文件添加到我的项目中似乎还不足以使用 FFmpeg。 (我按照 https://stackoverflow.com/a/21773572/1877798 作为引用指南)。有可能是我在项目中配置这些文件时做错了，或者是我在为 Android 构建 FFmpeg 时做错了。 (是否应该有更多文件？)

我想知道最近是否有关于在 Android 项目中构建或集成 FFmpeg 的指南。我正在使用 FFmpeg(截至 2014 年 2 月 27 日)和 Android NDK 9c。 如果没有，有人对其他图书馆有其他建议吗？我正在尝试获取一组图像文件并以编程方式创建视频/动画 gif。

谢谢! :-)

我找到了 http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/comment-page-4/和其他几个在 GitHub 上找到的。然而，他们似乎都在努力构建 FFmpeg。我正在使用 Mac OS X

这是我的脚本:

#!/bin/bash
NDK=/Downloads/android-ndk-r9c
SYSROOT=$NDK/platforms/android-18/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/darwin-x86_64
# Note: Change the TOOLCHAIN to match that available for your host system.
# darwin-x86_64 is for Mac OS X, but you knew that.
function build_one
{
./configure \
    --prefix=$PREFIX \
    --enable-shared \
    --disable-static \
    --disable-doc \
    --disable-programs \
    --disable-doc \
    --disable-symver \
    --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
    --target-os=linux \
    --arch=arm \
    --enable-cross-compile \
    --sysroot=$SYSROOT \
    --extra-cflags="-Os -fpic $ADDI_CFLAGS" \
    --extra-ldflags="$ADDI_LDFLAGS" \
$ADDITIONAL_CONFIGURE_FLAG
make clean
make
make install
}
CPU=arm
PREFIX=$(pwd)/android/$CPU 
ADDI_CFLAGS="-marm"
build_one

这是日志:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-        dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/c++/4.2.1

C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
