• FFmpeg more than 1000 frames duplicated and input height doesn't match

  2 septembre 2021, par Karine

  I'm currently using this code to record two windows side by side :

  


  ffmpeg -f gdigrab -framerate 30 -i title="" -f gdigrab -framerate 30 -i title="" -c:v h264_nvenc -qp 0 -filter_complex hstack=inputs=2 2.mp4


  


  However it throw this error after execution :

  


  More than 1000 frames duplicated


  


  Error Log : https://pastebin.com/gREVrKVK

  


  The first window mostly time is the same frame, maybe 1 frame change in each 3 sec.

  


  Another error in console is when the first window have a different height than second window, error :

  


  [Parsed_hstack_0 @ 000002491166fd00] Input 1 height 500 does not match input 0 height 488.
[Parsed_hstack_0 @ 000002491166fd00] Failed to configure output pad on Parsed_hstack_0


  


  Error log : https://pastebin.com/vqdBPfpv

  


  Looks like is not possible to record when they have different dimensions, so, if possible I would like to ask how to scale the first window to the same height (doesn't need to keep aspect ratio) of the second window, considering low CPU use above the video quality.

• is this right when i use the x264,thank you for your answer

  22 avril 2013, par chinayin

  is this right to use the new x264 api ,i want to get a frame ,and encode it with x264,then save it to a .264 file ?
  but i do not know is this is right ?
  picIn.img.plane[0] = pInBuffer ;
  picIn.img.plane[1] = pInBuffer +m_VideoEncParam.nWidth*m_VideoEncParam.nHeight ;
  picIn.img.plane[2] = pInBuffer +m_VideoEncParam.nWidth*m_VideoEncParam.nHeight*5/4 ;

  picIn.img.i_stride[0] = m_VideoEncParam.nWidth ;
  
  picIn.img.i_stride[1] = m_VideoEncParam.nWidth /2 ;
  
  picIn.img.i_stride[2] = m_VideoEncParam.nWidth /2 ;
  
  
  
  nRet = x264_encoder_encode(
  
                              m_pX264Handle,
  
                              &pNal,
  
                              &nNalCount,
  
                              &picIn,
  
                              &picOut);
  
  if (nRet<0)
  
  {
  
      return -1 ;
  
  }
  
  
  
  for (int i = 0 ;i<nnalcount></nnalcount>/memcpy(pOut+nLenOut,&amp;pNal[i],pNal[i].i_payload) ;
  
      x264_nal_encode(m_pX264Handle,pOutBuffer+nLenOut,&amp;pNal[i]);
  
      nLenOut += pNal[i].i_payload ;
  
  }
  
  int nSize = 0 ;
  
  FILE *pFile = fopen(pchFileName,"w") ;
  
  if (!pFile)
  
  {
  
      return -1 ;
  
  }
  
  nSize = fwrite(pOutBuffer,1,nLenOut,pFile) ;
  
  fclose(pFile) ;
