  As you can see,original video "Duration : 00:00:21.02",but the output file only "Duration 00:00:00.03".And the program exit no error.

  It didn’t convert entire file.

  What args I need to add ?

• Overlay Image on moving object in Video (Argumented Reality / OpenCv)

  30 juillet 2017, par Karandeep Atwal

  I am using FFmpeg to overlay image/emoji on video by this command -

  "-i "+inputfilePath+" -filter_complex "+"[0][1]overlay=enable='between(t,"+startTime+","+endTime+")'[v1]"+" -map [v0] -map 0:a "+OutputfilePath;  

  But above command only overlay image over video and stays still.

  In Instagram and Snapchat there is New pin feature. I want exactly same ,eg blur on moving faces or as in below videos -

  

  Here is link.

  Is it possible via FFmpeg ?

  I think someone with OPENCV or Argumented Reality knowledge can help in this. It is quiet similar to AR as we need to move/zoom emoji exactly where we want to on video/live cam.

• ffmpeg concat error-unusual video

  19 juillet 2017, par Samhita vempatti

  I have been trying to concatenate two 48 seconds video bits to one using the following command

      ffmpeg -f concat -safe 0 -i C:\moviepy-master\concat.txt -c copy output.mp4

  When I played it using Windows media player the first 48 second plays fine but the player closes before playing the second bit .

  Then I tried to play it using VLC media player but in the second bit player but the audio and video are not in sync .

  Then I also tried giving inputs separately so the following error shows up

              C:\Users\SAMHITA VVNK>ffmpeg -f concat -safe 0 -i C:\moviepy-master\extract1.mp4
  
               -i C:\moviepy-master\extract2.mp4 -c copy -flags +global_header output.mp4
