FFMPEG的机器人（使用教程：＆QUOT; ffmpeg的和Android.mk＆QUOT;） [英] ffmpeg for a android (using tutorial: "ffmpeg and Android.mk")

问题描述

我想编译的ffmpeg的机器人。我发现这个主题的几个职位，但非这些似乎工作。如果试图建立的ffmpeg像它张贴在[1]。有没有人用论文教程成功编译的ffmpeg？ 我不知道如何实现的步骤4〜5。

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.

第四步：配置...

第5步：cd到你的NDK根目录，输入make TARGET_ARCH =手臂APP = ffmpeg的，组织

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

在我看来，建立一个应用程序就像是在教程中介绍的步骤5需要一些previous步骤。不幸的是我的文件夹中没有应用程序，使。我现在用的是目前Android NDK版本3，并检查了实际的ffmpeg版本的[3] [4]。我很感谢每一个建议。

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.

基本上你的.so文件复制到你的JNI / lib目录，以及您可能需要，通过创建javah的JNI封装任何.h文件，和它的作品。

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.

由于这篇文章写了几个包装的ffmpeg项目为Android浮出水面，最简单的人之一，编译和使用是在这里：的 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 .

它采用了静态编译的二进制（而不是库）的方法，通过shell命令在运行时跑了。搜索github上的安卓的ffmpeg 的叉子和相关项目。

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.

没有找到一个很好的包装基础的方法JNI的实现，虽然。

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