• java.lang.UnsatifiedLinkError : no jniavutil in java.library.path using JavaCV FFmpegFrameGrabber

  31 mars 2015, par Noah Lutz

  I’m writing a program that is using JavaCV to grab frames from a stream. Its trying to use FFmpegFrameGrabber to capture the frames but when I try to run it, I get an UnsatisfiedLinkError.

  Here is the code :

  FrameGrabber frameGrabber;
  
      try{
  
          frameGrabber = new FFmpegFrameGrabber("http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8");
  
          frameGrabber.start();
  
  
  
          while(true){
  
              video.addFrame(new Frame(frameGrabber.grab()));
  
              System.out.println(video.getLength());
  
          }
  
      }catch(Exception e){
  
          e.printStackTrace();
  
      }

  And here is the stack trace :

  I have both OpenCV and FFmpeg installed and I followed the instructions for the manual installation of JavaCV on their github page.

  Thanks for your help.

• FFMPEG fails in node exec but succeeds on OSX

  10 avril 2015, par rrrkren

  So I’m trying to get a thumbnail of a mov video using ffmpeg.
  Here is the command :

  ffmpeg -i video.mov -vf scale=-1:100 -r 1 -an -vframes 1 -f mjpeg thumb.jpg

  it works fine when I type it in terminal. But once I do it in javascript (node) :
  (thumbPath, destPath, and thumbname are all defined earlier, and I doubt they are the problem)

  var command = "ffmpeg -i "+ destPath +" -vf scale=-1:100 -ss 00:01 -r 1 -an -vframes 1  -f mjpeg "+thumbPath+thumbname;
  
  exec(command,function(err){
  
      if(err){
  
          console.log(err);
  
      };
  
  });

  The console logs :

  video.mov: Invalid data found when processing input
  
  ] killed: false, code: 1, signal: null }

  I’ve looked up online and apparently the "moov atom not found error" is caused by the video being corrupted. But the command works fine when I type it in terminal. What’s wrong with my code ?

  Edit : This code works for mp4 videos, and the mov video was from an iPhone. I tried using a .mov file downloaded elsewhere and it works. Seems to be an issue with mov file shot with iPhone ?

• nodejs aws lambda ffmpeg command failure

  14 juin 2022, par mozenge

  Im running an ffmpeg command to generate a thumbnail from a video that exists on aws s3 bucket but accessed from cloud front. So i try to stream the video in the command. This is implemented in nodejs and the ffmpeg dependency is a lambda layer. The code looks like so

  


  const gifName = `${baseFilename}.gif`;
await execPromise(`ffmpeg -t 10 -ss 00:00:01 -i "${_url}" ${'/tmp/' + gifName}`);


  


  _url is a clound front url. This works when i test locally even via aws SAM cli.
But this fails when testing the deployed fuction. The error output I get is as follows
