Killing cmd processes in Bravobit FFmpeg
10 octobre 2018, par katarotyI am using
Bravobit FFmpegBravobit FFmpeg github toconvertsome audio files. There are more convertion than these 2 but I do not think they are necessary to add here.My question is, is it possible to kill or stop these commands once they are started.
At the moment when I start the first method
convertPCMToWav()and then callfinish()in theMain methodwhich stops all other processes but these. They just keep on going like nothing has happened.public class AudioProcessor {
private Context context;
private FFmpeg ffmpeg;
private File micPcmFile;
private File pcmtowavTempFile;
private File mp3towavTempFile;
public AudioProcessor(Context context, Activity activity) {
ffmpeg = null;
ffmpeg = FFmpeg.getInstance(context);
this.context = context;
prepare();
}
/**

* @throws Exception
*/
public void process() throws Exception {
if (!ffmpeg.isSupported()) {
Log.e("AudioProcessor", "FFMPEG not supported! Cannot convert audio!");
throw new Exception("FFMPeg has to be supported");
}
if (!checkIfAllFilesPresent()) {
Log.e("AudioProcessor", "All files are not set yet. Please set file first");
throw new Exception("Files are not set!");
}
Log.e("AudioProcessor", "Start processing audio");
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
convertPCMToWav();
}
}, 200);
}
