• I need the script open waiting for new files

  26 septembre 2019, par AUDICOM

  I use the following FFMPEG script for DAV to AVI file conversion :

  for %% A IN (* .dav) DO ffmpeg -i "%% A" -vcodec libx264 "%% A.avi

  But DAV files are generated in the folder every 30 minutes, the script is triggered when the 1st DAV file is generated, but the conversion is fast, and it finishes before the next DAV file is generated in the folder, I need the script. convert the DAV and wait for the next file to arrive in the folder, or after converting the last DAV file that arrives in the folder 12:00 PM the script terminates the process.

• avformat_open_input causes exception on RTP stream open

  3 avril 2014, par user3283475

  I'm trying to program a video player of the RTP stream. I'm using visual studio 2010. When avformat_open_input command is executed an exception is generated (ntdll.dll !774b70f4()). It works fine with normal file from disk(test.avi).

  #include "stdafx.h"
  
  #include 
  
  
  
  //zeranoe headers and libraries(DLLs also from zeranoe)
  
  extern "C"
  
  {
  
  #include <libavcodec></libavcodec>avcodec.h>
  
  #include <libavformat></libavformat>avformat.h>
  
  }
  
  
  
  #pragma comment(lib, "avcodec.lib")
  
  #pragma comment(lib, "avformat.lib")
  
  
  
  int _tmain(int argc, _TCHAR* argv[])
  
  {
  
      AVFormatContext *pFormatCtx=NULL;
  
      //char* Filename="c:\\test.avi"; //if I use this there is no crash
  
      char* Filename="rtp://239.255.42.42:5004";//if I use rtp I receive exception
  
      int videoStream,i;
  
      AVCodec         *pCodec=NULL;
  
      AVCodecContext  *pCodecCtx=NULL;
  
  
  
      avcodec_register_all(); 
  
      av_register_all();
  
      avformat_network_init();
  
  
  
      unsigned int _expTime = 5000;
  
      static const AVIOInterruptCB int_cb = {interrupt_cb, &amp;_expTime};
  
  
  
  
  
      // Open video file
  
      if(avformat_open_input(&amp;pFormatCtx, Filename , NULL,NULL)!=0)//ntdll.dll exception when I try to open rtp stream
  
      return -1; // Couldn&#39;t open file

  Can someone help me please ?
