• Mp3 file not showing in any media player after creating through ffmpeg

  4 mai 2019, par Aashit Shah

  Mp3 file not showing in any application after the mp3 file is saved . After 15 odd minutes it is automatically shown . if i manually change the name from file manager it will be instantly shown . How to solve this problem .

  Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
  
              String[] projection = {
  
                      MediaStore.Audio.Media.TITLE,
  
                      MediaStore.Audio.Media.DATA,
  
                      MediaStore.Audio.Media.DISPLAY_NAME,
  
                      MediaStore.Audio.Media.DURATION,
  
                      MediaStore.Audio.Media.ALBUM_ID
  
              };
  
              String sortOrder =  MediaStore.Audio.Media.DISPLAY_NAME
  
              Cursor c = getContentResolver().query(uri,projection,null,null,sortOrder);
  
              if(c.moveToFirst())
  
              {
  
                  do {
  
                      String title = c.getString(c.getColumnIndex(MediaStore.Audio.Media.TITLE));
  
                      String data = c.getString(c.getColumnIndex(MediaStore.Audio.Media.DATA));
  
                      String name = c.getString(c.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
  
                      String duration = c.getString(c.getColumnIndex(MediaStore.Audio.Media.DURATION));
  
                      String albumid= c.getString(c.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
  
                      Songs song = new Songs(title,data,name,duration,albumid);
  
                      songs.add(song);
  
                      title1.add(name);
  
                  }while (c.moveToNext());
  
              }

  Output file path :

   Environment.getExternalStorageDirectory()+ "/Trim"+".mp3";

  This is my command :

  "-y","-ss", start,"-i", input_path,"-t", end,"-metadata","title=Trim","-acodec", "copy","-preset", "ultrafast",output_path

• Is it possible to stream a video from FMLE directly to an media player without a mediation of FMS ?

  7 janvier 2015, par UserOfStackoverflow

  I want to know if it is possible to stream a video from FMLE (Flash Media Live Encoder) directly to an media player without a mediation of FMS (Flash Media Server) since I don’t want to restream it to many users ?

  Here is schematics of what I want (I hope it better explains my question) : http://s12.postimg.org/x4glz1l59/My_Scheme.png

  If it is possible then what media player(s) can do that ?

  Also if you know more tool like FMLE (Flash Media Live Encoder) or FFmpeg which can be controlled over command line please let me know !

  P.S.
  Thank you for your answers and suggestions also I hope that you like my drawing skills... :D

• How to loop over gif file finite number of times while creating mp4 as output with ffmpeg

  16 mai 2020, par in-user

  I am able to convert gif file to mp4 using this command :

  



  ffmpeg -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4


  



  What I want to do is to loop over gif animation 3 times and convert to mp4.

  



  I am able to do this with 2 shell commands. First one from above and then concatenate the same video 3 times.

  



  ffmpeg -f concat -safe 0 -i <(printf "file '$PWD/video.mp4'\n%.0s" {1..3}) -c copy videoloop.mp4


  



  I have also tried with -ignore_loop 0 option and setting time. It does work but it is not exactly what I am trying to do since I can extend the video but can not make exactly 3 loops.

  



  ffmpeg -ignore_loop 0 -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" -t 12 videoloop.mp4


  



  So as you can see I am already able to achieve what I want, but with 2 shell commands :

  



  ffmpeg -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4
ffmpeg -f concat -safe 0 -i <(printf "file '$PWD/video.mp4'\n%.0s" {1..3}) -c copy videoloop.mp4


  



  Is it possible to do this with only one call to ffmpeg ?

  



  I tried with -loop option for the input file. It doesn't work for gifs. I also tried with -stream_loop. It creates something corrupted.
