• Issue #2 when compiling Xuggler for Raspberry pi with libx264

  2 août 2014, par Ashish Sharma

  I am trying to compile Xuggler for Raspberry Pi(Running on Debian OS aka Raspbian),

  I followed the ’Basic Build Instructions’ available here for compiling Xuggler.

  After I successfully installed all the prerequisites and set the correct paths, I ran the following command :

  ant run-tests

  After sometime I am facing the following error and the ant build fails at libx264 :

  I am unable to understand the problem statment "unrecognized option ’-std=gnu99’" here, Can someone please tell me how can I resolve this or circumvent it in xuggler ?

• php-ffmpeg get video duration

  4 avril 2020, par swg1cor14

  When I try to get the duration of a video using the php-ffmpeg wrapper and ffprobe, I get a huge object instead of just the duration.

  



  $ffprobe = FFMpeg\FFProbe::create();
    $ffprobe->format($this->videoFile)
            ->get('duration'); 


  



  $this->videoFile is /home/admin/........./5422346433.mp4

  



  So it points to right file and the duration is listed in the giant object down in

  



  [[-show_format-/home/admin/web/admin.simplewebevents.com/public_html/cron/649652027.mp4][1]] => Array

                            )

                        [1] =>

            )


  



  But apparently ->get('duration') doesnt return the duration.

  



  I've also tried with

  



  $ffprobe
->streams($this->videoFile) // extracts streams informations
->videos()                      // filters video streams
->first()                       // returns the first video stream
->get('duration');
