MediaMetadataRetriever.getFrameAtTime() returns only first frame

Question

I have extracted frames from a video using MetadataRetriever, and have stored all images in an ArrayList. I want to store all of them on an SD car

Answer 1

long time;

    String formattedFileCount;
    FileOutputStream fos;
    BufferedOutputStream bos;

    NumberFormat fileCountFormatter = new DecimalFormat("00000");
    int fileCount = 0;
    File jpegFile;
    ArrayList bArray = null;
    Bitmap lastbitmap = null; 
    bArray = new ArrayList();

I am taking Time in microseconds and em getting duration from the Mediaplayer like:

time = mp.getDuration()*1000;
Log.e("Timeeeeeeee", time);


                bArray.clear();
                MediaMetadataRetriever mRetriever = new MediaMetadataRetriever();
                mRetriever.setDataSource(path);
                int  j=0;

My frame rate is 12 frame/sec so I divided 1/12 = 0.083333 and this is the second's part of a frame and than I convert my frame sec to microsecond so it becomes 83333

                for (int i = 833333; i <= time; i=i+83333) {
                    bArray.add(mRetriever.getFrameAtTime(i, MediaMetadataRetriever.OPTION_CLOSEST_SYNC));



                    formattedFileCount = fileCountFormatter.format(fileCount); 
                    lastbitmap = bArray.get(j);
                    j++;
                     // image is the bitmap
                        jpegFile = new File(Environment.getExternalStorageDirectory().getPath() + "/frames/frame_" + formattedFileCount + ".jpg");
                        fileCount++;

                        try {
                            fos = new FileOutputStream(jpegFile);
                            bos = new BufferedOutputStream(fos);
                            lastbitmap.compress(Bitmap.CompressFormat.JPEG, 15, bos);

                            bos.flush();
                            bos.close();
                        } catch (FileNotFoundException e) {

                            e.printStackTrace();
                        } catch (IOException e) {

                            e.printStackTrace();
                        }

                }

            } catch (Exception e) {


            }
