  I executed both ffprobe xxxx.mp4 and avcodec receive frame functions to decode one frame. reproduced the same error log.

  


  But when I open it using VLC or OBS it worked well. So,

  


  

  • does any error when I configure the options of ffmpeg ?

  


  • how to fix this problem ?

  


  


  the mp4 file I upload a piece in mp4 link

  


• Can't fix this ffmpeg, NoClassDefFoundError

  15 mars 2023, par noob234

  I am trying to get the video duration with this library import org.bytedeco.javacv.FFmpegFrameGrabber;

  


  When I upload this mp4 video (https://sample-videos.com/video123/mp4/720/big_buck_bunny_720p_1mb.mp4), I get this error message :
java.lang.NoClassDefFoundError: Could not initialize class org.bytedeco.ffmpeg.global.avutil

  


  It will break when trying to get the 'grabber' :

  


  private void videoInfo(MultipartFile file) {
    try (FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(file.getInputStream())) { // on this line it will break :(
        grabber.start();
        long durationMs = grabber.getLengthInTime();
    } catch (FrameGrabber.Exception e) {
        throw new RuntimeException(e);
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}

• Decode a proprietary (Genetec) H264 network video stream

  2 mars 2023, par al_mukthar

  I have incoming byte streams probably encoded in H264 from a Genetec camera through a websocket in my spring boot application,

  


  I need to decode the incoming H264 streams to transmit the video to my frontend clients.
I have tried using javaCV/FFMpeg but nothing works.

  


  I think, Genetec is using some custom encoding which is different from normal encoding

  


  Any help would be appreciated

  


  this is the part of hex dump received through socket

  UPDATE TO THE CODE

  


  1st Packet find here
2nd Packet find here

  


  I have updated the code as per one of the comment to read only MDAT box to retrieve H264 stream from the incoming bytes[] through the socket, now I send only MDAT box contents (next byte after MDAT box)

  


  public Map.Entry> hasMdat(byte[] byteArray) {
    for (int i = 0; i < byteArray.length - 3; i++) {
        if (byteArray[i] == (byte) 109 &&
                byteArray[i + 1] == (byte) 100 &&
                byteArray[i + 2] == (byte) 97 &&
                byteArray[i + 3] == (byte) 116) {

            return Map.entry(true, Arrays.asList(i, i + 1, i + 2, i + 3));
        }
    }
    return Map.entry(false, List.of(0));
}


  


  This is my code which handles the byte stream

  


  initSocketConnection(new VideoStreamCallback() {
        @Override
        public void onVideoStreamReceived(byte[] bytes) {
           
Map.Entry> b = hasMdat(bytes);
        if (b.getKey()) {
            byte[] b1 = Arrays.copyOfRange(bytes, b.getValue().get(3) + 1, bytes.length);
  //write b1 back to client using spring SSE
            
        }

        }
    });
