  • Pipe ffmpeg output as mjpeg on multicast port ?

    17 janvier 2020, par xor31four

    I am trying to open a h.264 encoded stream from an IP camera, re-encode and stream it to a multicast address on my local subnet.

    Found a post that seems to describe what I’d like to achieve but I am running into several issues.

    I am using this command :

    ffmpeg -re -i rtsp://192.168.0.11/stream1.sdp mpegts udp://239.168.0.1:11000

    and I am receiving this output :

    [h264 @ 000001531da0ad40] SPS unavailable in decode_picture_timing
    
[h264 @ 000001531da0ad40] non-existing PPS 0 referenced

    Where am I going wrong ? I am quite inexperienced in this field but determined to learn more.

    Thank you in advance for any pointers on how to go about this..

  • 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
