• automatically show blue screen in ffmpeg when live video source disconnects

  13 janvier 2015, par user1913115

  i’m capturing a live source using ffmpeg :

  ffmpeg -i rtsp://192.168.1.143/source -codec copy output.mp4

  which works great. the ip address is an address of an RTSP proxy server which takes in the camera itself as the source. i.e. my setup :

  camera ->> RTSP proxy ->> ffmpeg(output)

  if camera disconnects (accidentally or on purpose) the recording stops (obviously) and only continues when I re-connect the camera.

  Question : is there a way for ffmpeg to ’fill’ the down time with blue screen or green screen of some sort ?
  i know i can ’play’ a still image of a green screen using ffmpeg to record an mp4 out of it :

  ffmpeg -loop 1 -y -re -i green.jpg -r 30 -vcodec libx264 -an -f h264 greenvideo.mp4

  so i could set it up this way :

  ffmpeg(green) ->> ffmpeg(output)

  but I would need to run the command manually. is there a way for ffmpeg(output) to automatically detect the disconnect and use green.jpg as a ’video’ source ? or i can even create a 5-minute green.mp4 video of just green screen.

  put it another way, is it possible for ffmpeg to automatically switch input sources if one goes down ?

• ffmpeg not creating video from images

  16 décembre 2014, par Knight Rider

  I have read this Create Video using ffmpeg

  Stack Question for the Same

  Wiki Page for the same

  Still I am not able to get it.
  I have written this shell command in PHP

  echo $make_movie = "$ffmpeg -framerate 1/5 -i $folder_name/img%03d.png -c:v libx264 -r 25 -pix_fmt yuv420p $folder_name/output.mp4";

  This gives output

  ffmpeg\bin\ffmpeg.exe -framerate 1/5 -i ankit/img%03d.png -c:v libx264 -r 25 -pix_fmt yuv420p ankit/output.mp4
  
  
  
  if(shell_exec($make_movie)){
  
      echo "<br />Movie Created..<br />";
  
  }
  
  else{
  
      echo "<br />Movie Creation Error..<br />";
  
  }

  The Output is Movie Creation Error that means the Shell Command is not executing ?

  Questions :

  1. What is wrong ?
  2. For future use, any debugging methods for this ?

  I ran the same command on cmd and it made the video..!!!
