Add logo or watermark to Converted video using ffmpeg and PHP
27 mars 2022, par Medicare AdvisorsWe are converting videos to MP4 using FFMPEG.


We did a lot of research, however we cannot figure out how to add the company logo as a logo or a water mark to the converted video


PHP code


<?php 
$uploads_dir = 'original/';
$file_name = basename($_FILES['file']['name']);
$output_name = explode('.', $file_name)[0];
$uploaded_file = $uploads_dir . $file_name;
$convert_status = ['mp4' => 0, 'webm' => 0];

if(isset($_POST['submit'])) {
 if(move_uploaded_file($_FILES['file']['tmp_name'], $uploaded_file)) {
 // Make sure to get the correct path to ffmpeg
 // Run $ where ffmpeg to get the path
 $ffmpeg = '/bin/ffmpeg';
 
 // MP4
 $video_mp4 = $output_name . '.mp4';
 exec($ffmpeg . ' -i "' . $uploaded_file . '" -vcodec h264 -acodec libfdk_aac "./converted/' . $video_mp4 . '" -y 1>convert.txt 2>&1', $output, $convert_status['mp4']);

 // Debug
 // echo '<pre>' . print_r($output, 1) . ' </pre>';

 

 // Debug
 // echo '<pre>' . print_r($output, 1) . ' </pre>';
 }
}
?>


The logo we want to add is on : https://propeview.com/wp-content/uploads/2021/08/logo-whiteb.png

fftools/ffmpeg : Restore DTS correction for VP9 copies
12 mai 2021, par Danny Wufftools/ffmpeg : Restore DTS correction for VP9 copies
Fixes ticket 9086.
Since early 2021, some of YouTube's VP9 encodes have non-monotonous DTS.
This makes ffmpeg fatally fail when trying to copy or encode the V9 video.ffmpeg already includes functionality to correct this, however it was
disabled without explanation for VP9 stream copies in
2e6636aa87303d37b112e79f093ca39500f92364This patch restores the DTS correction logic, and allows ffmpeg to correctly
encode (invalid) videos produced by youtube.com. I have verified that frames
are NOT being cut (so it does not re-introduce 4313).Reviwed-by : Ronald S. Bultje <rsbultje@gmail.com>
