Android Studio with javaCv and FFMPEG

Question

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.

Process: com.example.calvintmoss.dejavid, PID: 1187

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?

Answer 1

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'

Here you are using bytedeco instead of googlecode now

Answer 2

I had the same problem, I took the library from google. Projects in use FFMpegRecoder and IplImage

My libs:

• javacv-0.7-src.zip

• javacv-0.7-bin.zip

• javacv-0.7-cppjars.zip
