• ffmpeg concat command of many files loses quality or makes result video to stall

  28 avril 2016, par edotom

  I have a Project that intends to have the union of several images and several videos converted to mp4 output.
  Source images come from a Windows App that converted bmps to jpgs. Those images were converted to mp4 using the following command :

  ffmpeg -report  -framerate 1/7 -i source.jpg -c:v libx264 -r 30 -pix_fmt yuv420p  destination.mp4

  Result video can be seen without problems.

  Source videos come from a vms in mkv format and are converted into mp4 using the following :

  ffmpeg -i source.mkv -vcodec copy -acodec copy destination.mp4

  As a result I have a series for different mp4 files that are copied to a txt file which will allow us to make a concatenation into a result mp4.

  The contents of txt will be something like this (jpgs should be placed alternately to videos) :

  file '1_VideoMkvto.mp4'
  
  file '2_VideoMkvto.mp4'
  
  file '3_BmptoJpg.mp4'
  
  file '4_VideoMkvto.mp4'
  
  file '5_BmptoJpg.mp4'
  
  file '7_VideoMkvto.mp4'
  
  file '8_JpgtoMp4.mp4'
  
  ....

  I use the following instruction :

    ffmpeg -report -f concat -i allVideos.txt -c copy results.mp4

  The issue that I’m experiencing is that in joined video, videos created originally from images (they were originally bmps converted to jpg) show problems like not being shown, shown for more or less time than original video or even worse... they make video player to stall when their part is played or closed without warning.

  Pd. I tried to concat all videos into one single file and all jpgs-mp4 into one single file and individually they can be seen easily, but when joined together, that’s when everything starts to fail.

• There is no sound with iFrameExtractor player

  22 octobre 2012, par why

  I has built ffmpeg and iFrameExtractor with ios5.1 successful, But when I play the video, There is no sound

  // Register all formats and codecs
  
  avcodec_register_all();
  
  av_register_all();
  
  avformat_network_init();
  
  
  
  
  
  if(avformat_open_input(&pFormatCtx, [@"http://somesite.com/test.mp4" cStringUsingEncoding:NSASCIIStringEncoding], NULL, NULL) != 0) {
  
      av_log(NULL, AV_LOG_ERROR, "Couldn't open file\n");
  
      goto initError;
  
  }

  The log is
