Code zum Hinzufügen von Audio zu Video mit ffmpeg.
Wenn die Audiolänge größer als die Videolänge ist, wird das Audio auf Videolänge reduziert. Wenn Sie volles Audio in Video wünschen, entfernen Sie -shortest vom cmd.
String[] cmd = new String[]{"-i", selectedVideoPath,"-i",audiopath,"-map","1:a","-map","0:v","-codec","copy", ,outputFile.getPath()};
private void execFFmpegBinaryShortest(final String[] command) {
final File outputFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/videoaudiomerger/"+"Vid"+"output"+i1+".mp4");
String[] cmd = new String[]{"-i", selectedVideoPath,"-i",audiopath,"-map","1:a","-map","0:v","-codec","copy","-shortest",outputFile.getPath()};
try {
ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
@Override
public void onFailure(String s) {
System.out.println("on failure----"+s);
}
@Override
public void onSuccess(String s) {
System.out.println("on success-----"+s);
}
@Override
public void onProgress(String s) {
//Log.d(TAG, "Started command : ffmpeg "+command);
System.out.println("Started---"+s);
}
@Override
public void onStart() {
//Log.d(TAG, "Started command : ffmpeg " + command);
System.out.println("Start----");
}
@Override
public void onFinish() {
System.out.println("Finish-----");
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// do nothing for now
System.out.println("exceptio :::"+e.getMessage());
}
