Android Studio与javaCv和FFMPEG [英] Android Studio with javaCv and FFMPEG

问题描述

所以我正在使用新的Android Studio，我试图在最基本的设置中安装JavaCV。我做了一个全新的项目，没有任何内容，导入（我认为不成功）JavaCV库，然后我运行JavaCV repo中给出的示例之一，我收到以下错误。

So I am using the new Android Studio and I am trying to get JavaCV installed in the most basic setup. I made a brand new project with nothing in it, imported (I think unsuccessfully) the JavaCV library and then I am running one of the samples given in the JavaCV repo and I am getting the following error.

我已经读了几个关于这个问题的其他顶级帖子，但我无法弄明白什么是错误的。我通过gradle下载了JavaCV，然后我添加了lib和lib / areabi文件夹。我将ffmpeg.jar，javacpp.jar，javacv.jar和opencv.jar全部导入到lib文件夹中。我从opencv-android-arm.jar和ffmpeg-android-arm.jar中提取了所有的.SO文件，并将它们放在lib / armeabi中，就像 git repo 。我不知道发生了什么。任何人都有什么想法？另外我目前的设置是。 Project-> AppModule然后里面是我有我的lib和lib里面我有armeabi。有没有人有任何关于发生什么的信息？

I have read several of the other top posts on the issue but I cannot figure out what is wrong. I downloaded the JavaCV through gradle, then I added the lib and lib/areabi folders. I imported ffmpeg.jar, javacpp.jar, javacv.jar and opencv.jar all to the lib folder. and I extracted all the .SO files from opencv-android-arm.jar and ffmpeg-android-arm.jar and put them in the lib/armeabi just like the instructions on the git repo. I cannot figure out what is going on. Anyone have any ideas? Also my current setup is. Project->AppModule and then inside of that is where I have my lib and inside of lib i have the armeabi. Does anyone have any info on whats going on?

推荐答案

尝试添加这五个依赖关系的代码：

Try to add these five codes in dependency:

compile 'org.bytedeco:javacv:+'
compile 'org.bytedeco.javacpp-presets:opencv:3.0.0-1.1:android-x86'
compile 'org.bytedeco.javacpp-presets:ffmpeg:2.8.1-1.1:android-x86'
compile 'org.bytedeco.javacpp-presets:opencv:3.0.0-1.1:android-arm'
compile 'org.bytedeco.javacpp-presets:ffmpeg:2.8.1-1.1:android-arm'

您现在使用的是bytedeco而不是googlecode。

Here you are using bytedeco instead of googlecode now
