• 12 ffmpeg xfade transitions : "option not found"

  17 juillet 2023, par nimda

  I'm running into a strange error where each of these following 12 of the 56 xfade transitions are throwing errors :

  


  

  • hlwind

  


  • hrwind

  


  • vuwind

  


  • vdwind

  


  • coverleft

  


  • coverright

  


  • coverup

  


  • coverdown

  


  • revealleft

  


  • revealright

  


  • revealup

  


  • revealdown

  


  


  I've tested all filter transitions with the following command, which is being generated by a nodeJS app with the fluent-ffmpeg library, and only the twelve listed above fail with the same error "option not found" :

  I have a problem in function avcodec_send_frame throwing error Error sending frame for encoding: Invalid argument (-22). I already search, check, recheck and nothing. It is near the ffmpeg examples. Can anyone help me ? Thanks.

• ffmpeg avformat_open_input always returns "Protocol not found" rv=(-1330794744)

  7 juin 2019, par bzivkovic

  Trying to get ffmpeg working in Visual Studio 2010. So far all ffmpeg headers and libs are loaded, no error or warning occurs.

  avcodec_register_all();
  
  AVFormatContext *pFormatCtx = NULL;
  
  char errbuf[256];
  
  pFormatCtx = avformat_alloc_context();
  
  int rv = avformat_open_input(&pFormatCtx, "myfile.ext", NULL, NULL);
  
  if (rv!=0){                              
  
      av_strerror(rv, errbuf, sizeof(errbuf));
  
  }

  The problem is, avformat_open_input always returning -1330794744 (errbuf="Protocol not found"). Tried x86 & x64 headers and libs on 32bit XP and 64bit W7. Whatever I put for "myfile.ext" (tried "file1.avi", "file=c :\file1.avi", "http://www.someweb.com/file1.avi", and even empty char* "") response is always "Protocol not found". Any ideas ?
