• LNK 2019 unresolved symbol - FFmpeg

  7 juin 2013, par Cristina1986

  I'm trying to use FFmpeg to open and read a video .avi
  I work on win7 x64 with Visual Studio 2010

  For now my code is very simple :

  #include "libavcodec/avcodec.h"
  
  #include "libavformat/avformat.h"
  
  #include "SDL.h"
  
  #include "SDL_mixer.h"
  
  
  
  
  
  int main (int argc, char *argv[]) {
  
  
  
  AVFormatContext *pFile_video;
  
  int             s, videoStream;
  
  AVCodecContext  *pCodecCtx;
  
  AVCodec         *pCodec;
  
  AVFrame         *pFrame; 
  
  AVFrame         *pFrameRGB;
  
  AVPacket        packet;
  
  int             frameFinished;
  
  int             numBytes;
  
  uint8_t         *buffer;
  
  
  
  av_register_all();
  
  
  
      if((avformat_open_input(&pFile_video, "AR.avi", NULL,NULL)!=0)) cout <<"cannot open video file"</if(av_find_stream_info(pFile_video) <0) cout <<"cannot retrive stream information"<nb_streams;s++){
  
          if((pFile_video->streams[s]->codec->codec_type) == AVMEDIA_TYPE_VIDEO) videoStream =s;
  
      }
  
      if(videoStream ==-1) cout <<"cannot open video stream"<code>

  I linked following .lib files :

  avcodec.lib
  
  avdevice.lib
  
  avfilter.lib
  
  avformat.lib
  
  avutil.lib
  
  postproc.lib
  
  swresample.lib
  
  swscale.lib

  but I get these errors :

  >MSVCRTD.lib(cinitexe.obj) : warning LNK4098: la libreria predefinita 'msvcrt.lib' è in conflitto con l'utilizzo di altre librerie; utilizzare /NODEFAULTLIB:libreria
  
  1>main_video_ffmpeg.obj : error LNK2019: riferimento al simbolo esterno "int __cdecl avformat_open_input(struct AVFormatContext * *,char const *,struct AVInputFormat *,struct AVDictionary * *)" (?avformat_open_input@@YAHPAPAUAVFormatContext@@PBDPAUAVInputFormat@@PAPAUAVDictionary@@@Z) non risolto nella funzione _SDL_main
  
  1>main_video_ffmpeg.obj : error LNK2019: riferimento al simbolo esterno "void __cdecl av_register_all(void)" (?av_register_all@@YAXXZ) non risolto nella funzione _SDL_main
  
  1>C:\Users\Cristina\Desktop\OpenCV\Progetti\MIEI_PROGETTI_Vs\video_ffmpeg\Debug\video_ffmpeg.exe : fatal error LNK1120: 2 esterni non risolti

  I think it is a linker error.. but I haven't other .lib file for FFmpeg library.

• Today we celebrate Data Privacy Day 2019

  28 janvier 2019, par Jake Thornton — Privacy
  Today we celebrate Data Privacy Day 2019 !!!

  What is Data Privacy Day ?

  Wikipedia tells us that : The purpose of Data Privacy Day is to raise awareness and promote privacy and data protection best practices.

  Our personal data is our online identity. When you think what personal data means – our phone records, credit card transactions, GPS position, IP addresses, browsing history and so much more. All so valuable and personal to us as human beings.

  That’s why we cannot take our personal data online for granted. We have a right to know which websites collect our data and how it’s then used, something that’s often not visible or easily recognisable when browsing.

  What Data Privacy Day means to Matomo

  Every year the team at Matomo uses this day as a chance to reflect on how far the Matomo (formerly Piwik) project has come. But then also reflect how far we still have to go in spreading the message that our data and personal information online matters.

  2018 saw the introduction of the EU General Data Protection Regulation (GDPR) to protect people’s data online. As a team, Matomo was at the forefront of this development in the analytics space and have since built a GDPR Manager to ensure our users can be fully compliant with the GDPR.

  With every new release of Matomo, we are ensuring that security continues to be at the highest standard and we will continue to be committed to our bug bounty program. Our most recent release of Matomo 3.8.0 alone added a Two Factor Authentication (2FA) feature and a password brute force prevention.

  What next for Matomo and data privacy ?

  As always, security is a top priority for every new release of Matomo and continues to only get better and better. We have a duty to spread our message further that the protection of personal data matters and today is a vital reminder of that. We are, and forever will be, the #1 open-source (and free to use) web analytics platform in the world that fully respects user privacy and gives our users 100% data ownership.

  In 2018 we changed our name, we updated our logo and website, and advanced our platform to compete with the most powerful web analytics tools in the world, all so we can spread our message further and continue our mission.

  Come with us on this exciting journey. Now is the time to take back control of your data and let’s continue creating a safer web for everyone.

  Please help us spread this message.
