Android ffmpeg command shows java.io.IOException : Error running exec()
26 mai 2023, par JamalI would like to use
ffmpegbinary executable in my Android project.for this purpose I have used pre built ffmpeg Android binary from this(https://github.com/hiteshsondhi88/ffmpeg-android/releases/download/v0.3.3/prebuilt-binaries.zip) link.


As per procedure I have to place the
executablefile into/data/data/com.example.rampedsampledirectory, herecom.example.rampedsampleis my project packageName.I couldn't find this location in my device as it is un rooted.So I pasted that executable intoAndroid emulator'scom.example.rampedsampledirectory usingDDMSperspective.


In my Activity used the below code



try {
 Process p = Runtime.getRuntime().exec("/data/data/com.example.rampedsample/ffmpeg "+Environment.getExternalStorageDirectory()+"/Movies/ramp_video.mp4"
 +" -map 0:v -codec copy "+Environment.getExternalStorageDirectory()+"/Movies/ramp_video2.mp4");


 } catch (IOException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }



AndroidManifest permission

How to install JavaCV on Android and use FrameGrabber
16 mars 2023, par MarkCould someone tell me where I'm doing wrong ? These are the steps that I have followed :


- 

-
Downloaded the adt-bundle-windows from android developer website


-
Created a new project and a libs/armeabi folder


-
Extract all the *.so files from javacv-android-arm.jar, opencv-2.4.3-android-arm.zip, and ffmpeg-1.0-android-arm.zip directly into the newly created "libs/armeabi" folder, without creating any new subdirectories.


(A part that I don't understand is "Extract all the *.so files from javacv-android-arm.jar", I simply inserted the javacv-android-arm.jar file inside libs/armeabi folder)


-
Navigated to Project > Properties > Java Build Path > Libraries and click "Add JARs...".


-
Selected both javacpp.jar and javacv.jar from the newly created "libs" folder.














After that I have downloaded OpenCV2.4.3 from here and ffmpeg from here and extracted the files on my C :/ root.
Finally after setting my system path...,


C:\opencv\build\x64\vc10\bin;C:\ffmpeg-64\bin;C:\Program Files\Java\jdk1.7.0_10\bin


...if I try to use simply FrameGrabber in my Android application...
