ffmpeg Exception : Working Directory : null Environment : null
13 décembre 2016, par DylanCreating the Android app, I am trying to crop video using ffmpeg library and store it in the app directory. I created the command :
String command = "ffmpeg -i /storage/emulated/0/DMC/diamondVideo.mp4 -vf crop=471:592:162:462 -c:a copy /storage/sdcard0/DMC/diamondVideoCropped.mp4";
String[] cmd = command.toString().split(" ");After that I pass this command to the AsyncTask :
new CropVideoTask().execute(cmd);
And in my AsyncTask I execute this command :
private class CropVideoTask extends AsyncTask {
protected Void doInBackground(String[]... cmd) {
FFmpeg ffmpeg = FFmpeg.getInstance(getContext());
try {
ffmpeg.execute(cmd[0], new ExecuteBinaryResponseHandler() {
@Override
public void onStart() {}
@Override
public void onProgress(String message) {}
@Override
public void onFailure(String message) {}
@Override
public void onSuccess(String message) {}
@Override
public void onFinish() {}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// Handle if FFmpeg is already running
}
return null;
}After the code enters in onStart method, it throw an Exception :
12-13 15:43:02.832 28941-32324/com.example.dmc E/FFmpeg: Exception while trying to run: [Ljava.lang.String;@42851b38
