  I’ve already download all the ts video segments using another Downloader , then try to follow the method to concatenate these ts video segments into a whole , however the ffmpeg complains the following

  C:\Users\i>ffmpeg -f concat -i mylist.txt -c copy output.ts

  so (1)what should I do to concatenate these encrypted m3u8 ts video segments into a whole ?
  (2) Any way to get the video byte size an m3u8 url referenced to ?

• Add image overlay for each millisecond the video using ffmpeg and php

  21 octobre 2016, par Domenike

  I need to add an image and different position for each millisecond the video frame, using php and ffmpeg.
  For example :
  In the first second I add an image in the X position, the next second another image in the position X.
  If you use the command directly on the terminal, the conversion is successful. But in PHP I have difficulties.
  In php, use the following command :

  <?php
  
  shell_exec('C:\\ffmpeg\\bin\\ffmpeg.exe -i C:\\ffmpeg\\bin\\vid.mp4 -i C:\\ffmpeg\\bin\\1.png -filter_complex "[0:v][1:v] overlay=100:25:enable=\'between(t,1,1.5)\'"  C:\\ffmpeg\\bin\\output1.mp4');
  
  sleep(20);
  
  echo "1";
  
  shell_exec('C:\\ffmpeg\\bin\\ffmpeg.exe -i C:\\ffmpeg\\bin\\output1.mp4 -i C:\\ffmpeg\\bin\\2.png -filter_complex "[0:v][1:v] overlay=10:25:enable=\'between(t,1.5,2)\'"  C:\\ffmpeg\\bin\\output2.mp4');
  
  sleep(50);
  
  echo "2";
  
  shell_exec('C:\\ffmpeg\\bin\\ffmpeg.exe -i C:\\ffmpeg\\bin\\output2.mp4 -i C:\\ffmpeg\\bin\\3.png -filter_complex "[0:v][1:v] overlay=250:25:enable=\'between(t,2,2.5)\'"  C:\\ffmpeg\\bin\\output1.mp4');
  
  sleep(20);
  
  echo "3";
  
  shell_exec('C:\\ffmpeg\\bin\\ffmpeg.exe -i C:\\ffmpeg\\bin\\output1.mp4 -i C:\\ffmpeg\\bin\\4.png -filter_complex "[0:v][1:v] overlay=300:25:enable=\'between(t,3,3.5)\'"  C:\\ffmpeg\\bin\\output2.mp4');
  
  sleep(20);
  
  echo "4";
  
  shell_exec('C:\\ffmpeg\\bin\\ffmpeg.exe -i C:\\ffmpeg\\bin\\output2.mp4 -i C:\\ffmpeg\\bin\\5.png -filter_complex "[0:v][1:v] overlay=350:25:enable=\'between(t,4,4.5)\'"  C:\\ffmpeg\\bin\\output1.mp4');
  
  sleep(70000);
  
  shell_exec('C:\\ffmpeg\\bin\\ffmpeg.exe -i C:\\ffmpeg\\bin\\output1.mp4 -i C:\\ffmpeg\\bin\\1.png -filter_complex "[0:v][1:v] overlay=400:25:enable=\'between(t,5,5.5)\'"  C:\\ffmpeg\\bin\\output2.mp4');

  I used the sleep function (PHP), but it did not work.
  Please, as I have not much experience with ffmpeg and php, you can help me.

  Thank you very much.

  just started coding in bash—how long can the lines in a script be or do i need to use the ’\’ character—if i do use the ’\’ character does it need a space after it ? TIA
