I'm trying to execute ffmpeg commands through an android app I'm developing.
I found this post which has been somewhat useful: Problems with ffmpeg command line on android
and I downloaded a static build of ffmpeg from here: http://ffmpeg.gusari.org/static/
The problem is, when this code runs
public void merge_video(){
String[] ffmpegCommand = new String[5];
ffmpegCommand[0] = "/data/data/com.example.zovideo/ffmpeg";
ffmpegCommand[1] = "-i";
ffmpegCommand[2] = "concat:storage/emulated/0/DCIM/Camera/VID30141106_211509.mp4|storage/emulated/0/DCIM/Camera/VID30141106_211509.mp4";
ffmpegCommand[3] = "copy";
ffmpegCommand[4] = "storage/emulated/0/DCIM/ZoVideo/Output.mp4";
try {
Process ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start();
String line;
BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream()));
Log.d(null, "*******Starting FFMPEG");
while((line = reader.readLine())!=null){
Log.d(null, "***"+line+"***");
}
Log.d(null,"****ending FFMPEG****");
} catch (IOException e) {
e.printStackTrace();
}
}
It fails when trying to start the process with
Java.io.IOException: Error running exec(). Command: [/data/data/com.example.zovideo/ffmpeg, -i, concat:storage/emulated/0/DCIM/Camera/VID30141106_211509.mp4|storage/emulated/0/DCIM/Camera/VID30141106_211509.mp4, copy, storage/emulated/0/DCIM/ZoVideo/Output.mp4] Working Directory: null Environment: [ANDROID_ROOT=/system, EMULATED_STORAGE_SOURCE=/mnt/shell/emulated, LOOP_MOUNTPOINT=/mnt/obb, LD_PRELOAD=libsigchain.so, ANDROID_BOOTLOGO=1, EMULATED_STORAGE_TARGET=/storage/emulated, EXTERNAL_STORAGE=/storage/emulated/legacy, SYSTEMSERVERCLASSPATH=/system/framework/services.jar:/system/framework/ethernet-service.jar:/system/framework/wifi-service.jar, ANDROID_SOCKET_zygote=10, PATH=/sbin:/vendor/bin:/system/sbin:/system/bin:/system/xbin, ANDROID_DATA=/data, ANDROID_ASSETS=/system/app, ASEC_MOUNTPOINT=/mnt/asec, BOOTCLASSPATH=/system/framework/core-libart.jar:/system/framework/conscrypt.jar:/system/framework/okhttp.jar:/system/framework/core-junit.jar:/system/framework/bouncycastle.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/telephony-common.jar:/system/framework/voip-common.jar:/system/framework/ims-common.jar:/system/framework/mms-common.jar:/system/framework/android.policy.jar:/system/framework/apache-xml.jar, ANDROID_PROPERTY_WORKSPACE=9,0, ANDROID_STORAGE=/storage]
I understand from the stackoverflow post I mentioned above that the ffmpeg static build needs to be on my device otherwise my app cannot use it.
However I'm unsure how to get it in the /data/data/com.example.zovideo folder as needed.
I have done is download the latest static ffmpeg build from http://ffmpeg.gusari.org/static/ and copied it into my libs/armeabi and libs/armeabi-v7a folders but this obviously hasn't succeeded in getting into the data/data folder when my app is installed onto my device. (I feel like I'm being an idiot by copy/pasting the files but I don't know what else to do. I don't know how to compile it myself - I have compiled ffmpeg using a Roman10 tutorial but this produces .so files which from which I understand is not what I need)
So I'm a little stuck. Any advice is greatly appreciated. Thanks
