ffmpeg for android（使用教程：“ffmpeg和Android.mk”） [英] ffmpeg for a android (using tutorial: "ffmpeg and Android.mk")

问题描述

我正在为一个android编译ffmpeg。我已经找到了这个主题的几个帖子，但这些帖子似乎都不起作用。如果试图建立ffmpeg喜欢它发布在[1]。有没有人使用这些教程成功编译ffmpeg？
我不知道如何实现步骤4到5。

I am trying to compile ffmpeg for a android. I have found several posts on this theme but non of these seems to work. If tried to build ffmpeg like it is posted on [1]. Did anybody successfully compile ffmpeg using theses tutorial? I am not sure how to realize step 4 to 5.

STEP4：配置...

STEP4: Configuring ...

STEP5：cd到您的NDK根目录，键入make TARGET_ARCH = arm APP = ffmpeg-org

STEP5: cd to your NDK root dir, type make TARGET_ARCH=arm APP=ffmpeg-org

在我看来，构建像这样的应用程序在第5步的教程中解释需要一些以前的步骤。不幸的是，我没有应用程序在文件夹中。我正在使用当前的Android ndk版本3，并检查出[3]和[4]中的实际ffmpeg版本。我感谢每一个建议。

It seems to me that building an application like it is explained in the tutorial in step 5 need some previous steps. Unfortunately I have no app in the folder to make. I am using the current android ndk release 3 and checked out the actual ffmpeg releases from [3] and [4]. I am thankful for every advice.

推荐答案

环顾网络。我发现唯一的工作解决方案是由Bambuser提供，它将ffmpeg移植到Android应用程序中。

After looking around the net. The only working solution I found is supplied by Bambuser which ported ffmpeg to use in their android application.

代码在这里： http://bambuser.com/opensource

基本上你将.so文件复制到你的jni / lib目录以及您可能需要的任何.h文件，通过javah创建一个JNI包装器，并且它可以工作。

Basically you copy the .so files to your jni/lib directory, along with any .h files you might need, create a JNI wrapper through javah, and it works.

编辑：

由于这篇文章是为几个打包的ffmpeg项目编写的，所以最简单的编译和使用之一就是： https://github.com/guardianproject/android-ffmpeg 。

Since this post was written a few packaged ffmpeg projects for android surfaced, one of the easiest ones to compile and use is here: https://github.com/guardianproject/android-ffmpeg .

它采用在运行时静态编译通过shell命令运行的二进制（而不是库）的方法。搜索github for'&$ code> android ffmpeg '用于叉和相关项目。

It takes the approach of statically compiling a binary (not a library) that is ran through shell command in run time. Search github for 'android ffmpeg' for forks and related projects.

没有找到基于JNI的打包方法

Did not find a well packaged method based JNI implementation, though.
