Answer 1

To Calculate ffmpeg progress in percentage

ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
            @Override
            public void onFailure(String s) {
                Log.d(TAG, "FAILED with output : " + s);
            }

            @Override
            public void onSuccess(String s) {
                Log.d(TAG, "SUCCESS with output : " + s);
            }

            @Override
            public void onProgress(String s) {
                Log.d(TAG, "Started command : ffmpeg " + Arrays.toString(command));
                Log.d(TAG, "progress : " + s);
                Pattern timePattern = Pattern.compile("(?<=time=)[\\d:.]*");
                Scanner sc = new Scanner(s);

                String match = sc.findWithinHorizon(timePattern, 0);
                if (match != null) {
                    String[] matchSplit = match.split(":");
                    if (totalDur != 0) {
                        float progress = (Integer.parseInt(matchSplit[0]) * 3600 +
                                Integer.parseInt(matchSplit[1]) * 60 +
                                Float.parseFloat(matchSplit[2])) / totalDur;
                        float showProgress = (progress * 100);
                        Log.d(TAG, "=======PROGRESS======== " + showProgress);
                    }
                }
            }

            @Override
            public void onStart() {
                Log.d(TAG, "Started command : ffmpeg " + Arrays.toString(command));
                progressDialog.setMessage("Processing...");
                progressDialog.show();
            }

            @Override
            public void onFinish() {
                Log.d(TAG, "Finished command : ffmpeg " + Arrays.toString(command));
                progressDialog.dismiss();
            }
        });

totalDur=25; // for 25 Sec Video

But totalDur will change according to operation like for 2x Slow Video you have to give totalDur=2*25; //50 Sec Video
