• Add logo or watermark to Converted video using ffmpeg and PHP

  27 mars 2022, par Medicare Advisors

  We 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

  


  &lt;?php &#xA;$uploads_dir = &#x27;original/&#x27;;&#xA;$file_name = basename($_FILES[&#x27;file&#x27;][&#x27;name&#x27;]);&#xA;$output_name = explode(&#x27;.&#x27;, $file_name)[0];&#xA;$uploaded_file = $uploads_dir . $file_name;&#xA;$convert_status = [&#x27;mp4&#x27; => 0, &#x27;webm&#x27; => 0];&#xA;&#xA;if(isset($_POST[&#x27;submit&#x27;])) {&#xA;  if(move_uploaded_file($_FILES[&#x27;file&#x27;][&#x27;tmp_name&#x27;], $uploaded_file)) {&#xA;    // Make sure to get the correct path to ffmpeg&#xA;    // Run $ where ffmpeg to get the path&#xA;    $ffmpeg = &#x27;/bin/ffmpeg&#x27;;&#xA;    &#xA;    // MP4&#xA;    $video_mp4 = $output_name . &#x27;.mp4&#x27;;&#xA;    exec($ffmpeg . &#x27; -i "&#x27; . $uploaded_file . &#x27;" -vcodec h264 -acodec libfdk_aac "./converted/&#x27; . $video_mp4 . &#x27;" -y 1>convert.txt 2>&amp;1&#x27;, $output, $convert_status[&#x27;mp4&#x27;]);&#xA;&#xA;    // Debug&#xA;    // echo &#x27;<pre>&#x27; . print_r($output, 1) . &#x27; </pre>&#x27;;&#xA;&#xA;   &#xA;&#xA;    // Debug&#xA;    // echo &#x27;<pre>&#x27; . print_r($output, 1) . &#x27; </pre>&#x27;;&#xA;  }&#xA;}&#xA;?>&#xA;

• hls.js starting a beginning with ANDROID mobile (chrome, webview also) and not live *** but works very nice in deskto, ios .. hls.js 1.0.0 2021-04-01

  27 avril 2021, par Jintor

  I'm streaming a .m3u8 with the latest hls.js 1.0.0 (not rc) but version of 2021-04-01...

  


  example : the stream began at 5pm, and now it's 5:15 pm...

  


  the stream start at live point in almost all browsers

  


  The pattern I see here : ALL browsers in android (tested in Android 10) won't start at live point, only at 0...

  


  I did all the tests

  How can this be fixed ?

  


  How can I make play at live point on load in android MOBILE ?

  


• Google AppEngine flex as a transcoder [closed]

  6 septembre 2021, par jACK

  Situation :

  


  

  • A Nodejs/Express application running on appengine flex.

  


  • Using FFmpeg to cut videos, and merge different types of videos. 1080p 30fps videos, merged video duration usually around 8 hours.

  


  • Need for a massive amout of processing power for those edits.

  


  • The express server needs to be reachable 24/7 & flex is incredibly expensive if run on a 24/7 basis.

  


  


  Goal :

  


  

  • To have a cost efficient ffmpeg transcoder on a private enviroment =>

  


  • Flex instance as a maximum spec, but as its idle reduce the price significantly.

  


  


  Or is this a situation where a redesign is imminent ? eg. Compute Engine

  


  Tried approach

  


  

  • B8 Standard instance => Since the payload is pretty big, its causing the B8 instance to crash.

  


  


  Thanks.
