我看到了很多有关FFmpeg和在Android中使用FFmpeg的帖子，但我发现这些帖子大多数是针对较旧版本的FFmpeg或Android NDK。我能够从https://github.com/mconf/android-ffmpeg获得结果，其中包括文件："libavcodec.so"、"libavformat.so"、"libavutil.so"和"libswscale.so"。然而，仅仅将这些文件添加到我的项目中似乎不足以使用FFmpeg。(我按照https://dev59.com/am445IYBdhLWcg3wnrgi#21773572作为参考指南)。可能是我在配置这些文件时做错了些什么，或者我在为Android构建FFmpeg时做错了些什么。(还应该有更多文件吗？)
我想知道有没有最近的指南来构建或集成FFmpeg到Android项目中。我正在使用FFmpeg(截至2014年2月27日)和Android NDK 9c。 如果没有，有没有其他库的推荐？我正在尝试使用一组图像文件并编写程序创建视频/动画GIF。
谢谢！:-)

我找到了http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/comment-page-4/和其他一些在GitHub上发现的指南。然而，它们都似乎在构建FFmpeg方面存在问题。我在使用Mac OS X。以下是我的脚本：

/Downloads/android-ndk-r9c/toolchains/arm-linux-androideabi-4.8/prebuilt/darwin-x86_64/bin/arm-linux-androideabi-gcc is unable to create an executable file.
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.
