• How to merge two videos from Firebase Database and local file? [closed]

  2 April 2020, by i i

  I need to merge two videos from a local file and Firebase Storage. How can I solve it?
I can get the file from a local file but I couldn't get the video from Firebase Storage.

  



  Part of my code:

  



  if(secondlength >0){
        if (secondlength > secondinterval) {
            final File source = new File(files.get(1));
            //  String filename = "https://firebasestorage.googleapis.com/v0/b/***.appspot.com/o/video_covers%2Fvideo_ornek.mp4?alt=media&token=10c3fa8a-4510-4984-8247-8036fffe18b3";
            //  filesname.add(filename);
            //  final File output = new File(Uri.parse(filename).getPath());
            String filename = String.format(Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp4");
            filesname.add(filename);
            final File output = new File(filename);
            startTrim(source, output, startsecond, startsecond + secondinterval);
            startsecond = startsecond + secondinterval + .7;
            secondlength = secondlength - secondinterval;
            Log.e("filename2 in 10", "" + filename);
        } else {
            final File source = new File(files.get(1));
            String filename = String.format(Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp4");
            filesname.add(filename);
            final File output = new File(filename);
            String DownloadUrl = "https://firebasestorage.googleapis.com/v0/b/*****.appspot.com/o/video_covers%2Fvideo_ornek.mp4?alt=media&token=10c3fa8a-4510-4984-8247-8036fffe18b3";
            DownloadManager.Request request1 = new DownloadManager.Request(Uri.parse(DownloadUrl));
            request1.setDescription("Sample Music File");   //appears the same in Notification bar while downloading
            request1.setTitle("File1.mp3");
            request1.setVisibleInDownloadsUi(false);

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                request1.allowScanningByMediaScanner();
                request1.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN);
            }
            request1.setDestinationInExternalFilesDir(getApplicationContext(), "/File", "Question1.mp4");

            DownloadManager manager1 = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
            Objects.requireNonNull(manager1).enqueue(request1);
            if (DownloadManager.STATUS_SUCCESSFUL == 8) {
                Toast.makeText(AllVideoMerge.this, "success", Toast.LENGTH_SHORT).show();
            }

            startTrim(source, output, startsecond, startsecond + secondlength);
            startsecond = 0;
            secondlength = 0;


            Log.e("filename2", "" + filename);
        }
    }

  I’m trying to make an overlay with a mask over a transparent image with ffmpeg, but the background of the image that gets the mask turns black, is there any way to make this background remain transparent?

  ffmpeg -i background.jpg -loop 1 -i image.png -loop 1 -i mask.png -filter_complex [0]setpts=PTS-STARTPTS,scale=720:720[background];[2]alphaextract,scale=640x320[mask];[1]scale=640x320[image];[image][mask]alphamerge[final_mask];[background][final_mask]overlay=100:100[final] -map [final] -t 00:00:05.000 -y result.mp4

• there is no sound after adding a logo to a video moviepy

  1 June 2021, by NKG

  I have a video with sound.
Then, using moviepy I am adding a logo.png on the video.
The video with the logo has sound, but when I upload it onto instagram there is no sound(
P.S. the original video uploaded onto the instagram has sound.

  


  there is a code bellow

  


  import moviepy.editor as mp


INPUT_FILE_PATH = rf'input\video.mp4'
OUTPUT_FILE_PATH = rf'output\video.mp4'

video = mp.VideoFileClip(INPUT_FILE_PATH)


logo = (mp.ImageClip("logo.png")
        .set_duration(video.duration)
        .resize(width=width / 3)
        .margin(right=width // 20, top=5 * height // 8, opacity=0)  # (optional) logo-border padding
        .set_pos(("right", "top")))

final = mp.CompositeVideoClip([video, logo])


final.write_videofile(OUTPUT_FILE_PATH, fps=30, codec="libx264", audio_fps=22050, audio_bitrate="31k")


  


  Maybe I need add some params to output video, But I don't know what params
