• FFmpeg error : Failed to resolve hostname

  29 octobre 2016, par David Barishev

  I’m using FFmpeg on android, and i have a strange error show up, that does not occur when i’m executing it on my linux VM.
  I’m using FFmpeg Static Builds, from here.
  I am using the stable 3.1.5 x86_64 build on the emulator and the linux VM.

  Here is the log :

  Since im using the same build for each platform, what is blocking the android one from working ? Is it something with android platform not allowing connections from static libraries ?

• System reboots during ffmpeg tool installation

  I have enabled QSV with reference of the streambuilder’s enabling-iqsv docs.

  I have installed ffmpeg with —enable-nonfree —enable-libmfx configurations, configuration command was successfully done.Then, I invoke make and our server gets hanged in few seconds and it will gets rebooted automatically.

  I feel it might be compilation issue with make script.

• Exception in thread "main" java.lang.UnsatisfiedLinkError : no jniavutil in java.library.path

  29 novembre 2016, par tpm900

  I am trying to split a video into frames using FFmpegFrameGrabber (using code I have seen in tutorials) but am getting an exception as follows :

  The code :

  public BufferedImage getNextFrame() {
  
      FFmpegFrameGrabber fFmpegFrameGrabber = new FFmpegFrameGrabber("resources/WebPage.mp4");
  
      BufferedImage bufferedImage = null;
  
      opencv_core.IplImage i;
  
      try {
  
          fFmpegFrameGrabber.start();
  
          i = fFmpegFrameGrabber.grab();
  
          bufferedImage = i.getBufferedImage();
  
      } catch (Exception e) {
  
          e.printStackTrace();
  
          try {
  
              fFmpegFrameGrabber.stop();
  
          } catch (Exception e1) {
  
              e1.printStackTrace();
  
          }
  
      }
  
      return bufferedImage;
  
  }
