• 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

• getting errors from FFMpeg when spawned from .NET

  18 mars 2014, par Brannon

  When I run FFMpeg from the command line like this

  ffmpeg.exe -hwaccel auto -re -i "C:\Users\Public\Videos\Sample Videos\Wildlife.wmv" -an -sn -c:v bmp -pix_fmt bgr24 -f rawvideo - > junk.bin

  it works fine. However, when I spawn the exact same thing (minus > junk.bin) I get this nasty "bad header" error after a few seconds of playback. What is causing this ? I have trouble believing my process blocks the pipe longer than the filesystem does, but it should be able to block the pipe indefinitely without defeating the decoding. The truncated stderr is below. My code to spawn the thing is here.

• Easy Tricks for Finding WebM Videos in YouTube

  9 août 2010, par noreply@blogger.com (John Luther)

  Since the WebM project launch, YouTube has been encoding videos uploaded at 720p or higher resolution in the WebM format. Today, the one million most popular videos of any size on YouTube are also available in the WebM format.

  We have instructions on our project site for finding these videos but they require adding a special parameter onto the end of each search query. All of the browsers that support WebM can create search shortcuts with custom parameters, however, so we’ve compiled instructions for making it very simple to search for WebM videos in YouTube.

  Important : First, make sure you have a supported browser and are enrolled in the YouTube HTML5 beta by going to http://youtube.com/html5 and clicking Enter the HTML5 Beta.

  Creating a WebM Search Shortcut

  Firefox 4 Beta :
  

  1. Select Bookmarks > Organize Bookmarks. A bookmark manager dialog opens.
  2. In the left column, choose a location for the new bookmark you’re creating. Next, choose Organize > New Bookmark (on MacOS click the gear icon). The new bookmark dialog opens.
  3. In the Name box, type WebM.
  4. In the Location box, type http://youtube.com/results?search_query=%s&webm=1.
  5. In the Keyword box, type webm.
  6. Click Add.

  Google Chrome Early Release Channel :
  

  1. On Windows and Linux, click the Chrome wrench icon in the toolbar and select Options. On MacOS, select Chrome > Preferences.
  2. On the Basics tab, click the Manage button in the Default Search section.
  3. On Windows and Linux, click Add. On MacOS X, click the plus (+) button.
  4. In the Name box, type WebM.
  5. In the Keyword box, type webm.
  6. In the URL box, type http://youtube.com/results?search_query=%s&webm=1.
  7. Click OK.

  Opera 10.60 and later :
  

  1. Go to http://youtube.com.
  2. Right-click in the YouTube search box at the top of the page and select Create Search. On MacOS, use Ctrl+click if you don’t a secondary mouse button enabled.
  3. In the Name box, type WebM.
  4. In the Keyword box, type webm.
  5. In the Address box, type http://youtube.com/results?search_query=%s&webm=1.
  6. Click OK.

  
  

  
  Now you’re ready to search. In the location box of the browser, type webm monster trucks. The YouTube search results page will open with a selection of monster truck videos encoded in the WebM format. When watching a video, look for the HTML5 WebM indicator in the player control bar.

  If you can’t find WebM videos it is most likely a browser cookie problem. Your enrollment in the YouTube HTML5 beta test is stored in a browser cookie (not in your YouTube or Google account), and that cookie can expire. Visit http://youtube.com/html5 and opt-in again to re-set the cookie.

  Directly Accessing WebM Videos by URL

  To find out if any YouTube video is available in WebM, simply add &html5=True (make sure True is capitalized) to the end of the video URL. If there is a WebM version of the video, it will open instead of the Flash version. For example :
  

  • Flash version : http://www.youtube.com/watch?v=Dz6gFokvOr0
  • WebM version : http://www.youtube.com/watch?v=Dz6gFokvOr0&html5=True
