• 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.

• Use a video editing library (not executable) via Node [on hold]

  25 septembre 2018, par Merc

  I need to edit clips using node. I am looking around, and most (if not all) libraries seem (like Fluent FFMpeg) seem to be based on the fact that they run FFMPEG as an executable and get the resulting output.

  That’s not what I want. I worked with FFMPEG executable in the past, and I know how flaky it is in terms of return codes and error codes.

  Ideally, I would love to find a native library for video editing and make calls using node.

  In terms of libraries :

  • Gstreamer
  • FFmpeg/LibAV (does they come with C libraries to bind to ?)
  • libVLC

  In terms of binding with them :

  • node-gir. Gstreamer seems to have updated git files

  • native bindings. For example Gstreamer has gstreamer-superficial. I couldn’t find any javascript bindings forFFMPEG — only "run the executable and hope for the best" libraries

  • VLC has a bindings library that is quite old and had its last commit years ago.

  Am I getting this all wrong ?
  My ideal outcome is to have a nice, robust library that I use directly using node, but my lack of experience in terms of using native libraries, and the somehow fragmented world of video editing libraries.

• Add FUNDING.json

  19 juin, par Michael Niedermayer

  Add FUNDING.json
  We have been contacted by Monet du Plessis of the etherium foundation and
  
  Natascha Buck (Grants at the Better Internet Foundation)
  "The Ethereum Foundation is thrilled to inform you that your contribution to
  
   open-source software development through your work on ffmpeg
  
   https://github.com/FFmpeg/FFmpeg  has been recognized and rewarded by the
  
   Devcon team ! Your project played a fundamental role in the success of Devcon
  
   <http://devcon.org/>, helping to create a more meaningful experience for
  
   the Ethereum community. In collaboration with Drips Network
  
   <https://www.drips.network/>, we are pleased to award you $2,240.00 in
  
   appreciation of your efforts and to support your continued efforts in
  
   open-source development."
  To be able to claim donations through the drips network we need to
  
  specify a wallet to do so in FUNDING.json
  This will also allow FFmpeg to receive future funding and donations
  
  through the drips network.
  The specified wallet is a safe wallet backed by a ledger hw wallet.
  
  We can later change who controls the safe wallet. (For example it
  
  could be passed on to the SPI treasurer)
