    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.

    libavformat/matroskadec : fix unsigned overflow to improve seeking

    When seeking a file where codec delay is greater than 0, the timecode
    
can become negative after offsetting by the codec delay. Failing to cast
    
to a signed int64 will cause the check against skip_to_timecode to evaluate
    
true for these negative values. This breaks the "skip_to" seek mechanism.

  • Green screen on RTSP stream from USB camera using mediamtx (ffmpeg) [closed]

    27 juin 2024, par Pavel

    I need to cast a stream from a USB camera via RTSP as stable as possible (at any moment i need to be able to get a static picture on a remote host, reflecting the real state of affairs in front of the camera) and economically on the used resources (the hardware is very weak).

    &#xA;

    Camera information. The options highlighted in yellow are those found on all cameras in use.

    &#xA;

    Trying to write mjpeg to rtsp only displays green screen

    &#xA;

    And mediamtx output output

    &#xA;

    runOnInit in mediamtx.yml :

    &#xA;

    FFmpeg -hwaccel_output_format qsv -fflags nobuffer -f dshow -vcodec mjpeg_qsv -s 640x480 -i video="Integrated Webcam" -vcodec copy -f rtsp rtsp://localhost:$RTSP_PORT/$RTSP_PATH&#xA;

  • Streaming a video with serial port [on hold]

    23 août 2019, par kanki66

    I need an application which is streaming an video recorded by an webcam over the serial port in c#

    I opened an port and can send some data over the port. I have access to the webcam and have an picture/video on the screen. For the webcam part i used this tutorial :
    https://en.code-bude.net/2013/01/02/how-to-easily-record-from-a-webcam-in-c/

    void videoSource_NewFrame(object sender, AForge.Video.NewFrameEventArgs eventArgs)
    
{
    
  //Cast the frame as Bitmap object and don't forget to use ".Clone()" otherwise
    
  //you'll probably get access violation exceptions
    
  pictureBoxVideo.BackgroundImage = (Bitmap)eventArgs.Frame.Clone();
    
}

    How can i convert now this to an video as small as possible and send it over the serial port, without saving the video like directly to the serial port ?

    Thank you very much for the help
