  avfilter/dnn : Remove a level of dereference
  For code such as 'model->model = ov_model' is confusing. We can
  
  just drop the member variable and use cast to get the subclass.

• How to send AVPacket through a QTcpSocket.write() with all of its data ?

  24 juin 2024, par CottonBuds

  I want to send an AVPacket though a QTcpSocket.write() I tried to cast the avpacket pointer to an char * but it only shows 8 bytes of the avpacket and without the avpacket.data.

  


  

  


  here is my code

  


  void DisplayStreamServer::sendDataToClient(AVPacket* packet) {
    if (client == nullptr) {
        return;
    }


    client->write((char*) packet);
    client->waitForBytesWritten();

    av_packet_unref(packet);
    av_packet_free(&packet);
}


  


  I can see that my packet.data has data inside it using the visual studio memory viewer. but it seems like when i convert the packet to char * the data is not included

  


  

  


• 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).

  


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

  


  Trying to write mjpeg to rtsp only displays green screen

  


  And mediamtx output output

  


  runOnInit in mediamtx.yml :

  


  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


  


  Thank you for your help
