• FFmpeg file not found exception, No such file or directory

  16 avril 2020, par Sagar

  I am getting the No such file or directory exception on video trimming.

  



  video path : /storage/emulated/0/Pictures/Instagram/Fast & Furious 7 - Get Low Extended Version Video.mp4

  



  file name : Fast & Furious 7 - Get Low Extended Version Video.mp4

  



  and ffmpeg searching for only Fast in/storage/emulated/0/Pictures/Instagram/Fast: No such file or directory


  



  I have found the issue, it is causing due to the file name having spaces in between them you can check in the above mentioned path and in exception.

  



  after changing the file name its working but the changing name of every file from the device it's not the right way so how can I solve this exception

• How to decrypt hls video content

  16 mai 2019, par SHAH MD MONIRUL ISLAM

  My requirement is to play the encrypted hls video files from local storage in android. I have used NanoHTTPD to create and run the local server. From there I am serving the .ts an .m3u8 files. To play this video ExoPlayer need a key to decrypt the files and thus I made a url : http://localhost:4990/dataKey.

  Here is my local server class :

  import android.os.Environment;
  
  import android.util.Log;
  
  
  
  import java.io.File;
  
  import java.io.FileInputStream;
  
  import java.io.FileNotFoundException;
  
  import java.util.Map;
  
  
  
  import fi.iki.elonen.NanoHTTPD;
  
  
  
  public class LocalStreamingServer extends NanoHTTPD{
  
      public LocalStreamingServer(int port){
  
          super(port);
  
  
  
      }
  
  
  
      @Override
  
      public Response serve(IHTTPSession session){
  
          Log.e("req", session.getUri());
  
  
  
          if(session.getUri().equalsIgnoreCase("/dataKey")){
  
  
  
              return newFixedLengthResponse(Response.Status.OK, "txt", "what is the key?");
  
          }
  
  
  
          if(session.getUri().contains("m3u8")){
  
              String path = Environment.getExternalStorageDirectory().toString() + "/s3" + session.getUri();
  
  
  
              FileInputStream fis = null;
  
              File f = new File(path);
  
              try {
  
                  fis = new FileInputStream(f);
  
              } catch (FileNotFoundException e) {
  
              }
  
              return newFixedLengthResponse(Response.Status.OK, "m3u8", fis, f.length());
  
          }
  
  
  
          if(session.getUri().endsWith("ts")){
  
              String path = Environment.getExternalStorageDirectory().toString() + "/s3" + session.getUri();
  
  
  
              FileInputStream fis = null;
  
              File f = new File(path);
  
              try {
  
                  fis = new FileInputStream(f);
  
              } catch (FileNotFoundException e) {
  
  
  
              }
  
              return newFixedLengthResponse(Response.Status.OK, "ts", fis, f.length());
  
          }
  
  
  
          String path = Environment.getExternalStorageDirectory().toString() + "/s3/master.m3u8";
  
  
  
          FileInputStream fis = null;
  
          File f = new File(path);
  
          try {
  
              fis = new FileInputStream(f);
  
          } catch (FileNotFoundException e) {
  
          }
  
          return newFixedLengthResponse(Response.Status.OK, "m3u8", fis, f.length());
  
      }
  
  }

  I have transcoded the video using ffmpeg. I need to know that which data or key need to be returned when the dataKey url is called. I have the encrypted the video using these key :

  key=617D8A125A284DF48E3C6B1866348A3F
  
  IV=5ff82ce11c7e73dcdf7e73cacd0ef98

  I can not understand which of them are need to be returned from the datakey url. Both of them are not working. Exoplayer is sending the error message :java.security.InvalidKeyException: Unsupported key size

  can Any one help me about this ?
