• live video streaming not playing on dash.js player using ffmpeg, nginx-rtmp in raspberry pi

  15 août 2016, par sparks

  I am trying to stream a live video from raspberry pi & pi camera module to web browser.But the video doesn’t play.I am using Nginx-rtmp and ffmpeg to process the video. On the client side i use dash js player trying to play the video but no luck.I see the warning on the terminal

  [flv @ 0x2c3b950] Failed to update header with correct duration.
[flv @ 0x2c3b950] Failed to update header with correct filesize.

  But i am not sure if this could be the issue. Anybody knows what might be wrong ?I don’t expect a straight answer but i am sure somebody can guide me in the right direction. Thank you in advance. Here is my set up

• AFTER PHP-FFMpeg not converting (error with ffmpeg)

  15 août 2016, par Magurean Dan Sergiu

  I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

  Use -h to get full help or, even better, run 'man ffmpeg'

  But when I try to convert a video file with a php script it throws me a very long error.
  PHP Code :

  <?PHP
  
  include($_SERVER['DOCUMENT_ROOT']."/vendors/install/vendor/autoload.php");
  
  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open($_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.wmv');
  
  $video
  
         ->filters()
  
         ->synchronize();
  
  $format = new FFMpeg\Format\Video\X264();
  
  $format->on('progress', function ($video, $format, $percentage) {
  
      echo "$percentage % transcoded";});
  
  $video
  
        ->save($format,$_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.mp4');
  
  ?>

  Error displayed :

  Then I have took the basic code displayed upwards and ran it directly through ssh.

  Unknown encoder 'libx264'

  My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

  After a few modifications

  I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.
