Android - 集成ffmpeg和android-ndk-r9c [英] Android - Integrating ffmpeg and android-ndk-r9c

问题描述

我看过很多关于FFmpeg的帖子，在Android中使用了FFmpeg，但是我发现这些帖子中的大多数都是FFmpeg或Android NDK的旧版本。我能够从 https://github.com/mconf/android-ffmpeg，其中包括文件：libavcodec.so，libavformat.so，libavutil.so，libswscale.so。但是，只需将这些文件添加到我的项目中似乎不足以使用FFmpeg。 （我遵循 https://stackoverflow.com/a/21773572/1877798 作为参考指南）。有可能我在我的项目中配置这些文件时出错了，或者我为构建FFmpeg for Android做错了事情。 （应该有更多的文件？）

我想知道是否有任何最近的指南，用于在Android项目中构建或集成FFmpeg。我正在使用FFmpeg（截至2/27/14）和Android NDK 9c。
如果没有，有没有人有其他图书馆的其他建议？我正在尝试采取一组图像文件，并以编程方式创建一个视频/动画GIF。

谢谢！ ： - ）

我发现 http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/comment-page-4/ 和其他几个在GitHub上发现的。但是，他们似乎都在努力建设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 
＃注意：更改TOOLCHAIN以适应您的主机系统。 
＃darwin-x86_64适用于Mac OS X，但您知道。 
函数build_one

 ./configure \ 
 --prefix = $ PREFIX \ 
 --enable-shared \ 
 --disable -static \ 
 --disable-doc \

 --cross-prefix = $ TOOLCHAIN / bin / arm-linux-androideabi- \

 --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：

I have seen a lot of posts about FFmpeg and using FFmpeg in Android, but I am finding that a majority of these posts are for older versions of either FFmpeg or Android NDK. I was able to get a result from https://github.com/mconf/android-ffmpeg, which includes the files: "libavcodec.so", "libavformat.so", "libavutil.so", "libswscale.so". However, simply adding these files to my project does not seem to be enough to use FFmpeg. (I followed https://stackoverflow.com/a/21773572/1877798 as a reference guide). It's possible that either I've done something wrong in configuring these files in my project, or I've done something wrong in building FFmpeg for Android. (Should there be more files?)

I was wondering if there are any recent guides for building or integrating FFmpeg in an Android project. I am using FFmpeg (as of 2/27/14) and Android NDK 9c.
If not, does anyone have other recommendations for other libraries? I am trying to take a set of image files and create a video/animated gif programatically.

Thanks! :-)




~~ EDIT ~~

I have found http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/comment-page-4/ and a couple others found on GitHub. However, they all seem to struggle in building FFmpeg. I am using Mac OS X

Here is my script:

# Note: Change the TOOLCHAIN to match that available for your host system.
# darwin-x86_64 is for Mac OS X, but you knew that.

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
[e-mail] 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.
