    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.

  • How to generate a gif image from a video with laravel-ffmpeg ?

    27 août 2021, par Jeannot21

    I am working on a project with laravel 7 and ffmpeg my problem is that I would like to generate a gif image from a video uploader but its not working.

    


    I created a job named ConvertImageGifFromVideo here is its code :

    


    class ConvertImageGifFromVideo implements ShouldQueue
{
 use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

/**
 * Create a new job instance.
 *
 * @return void
 */
public $video;
public function __construct(Video $video)
{
    $this->video = $video;
}

/**
 * Execute the job.
 *
 * @return void
 */
public function handle()
{

    $destination = '/'.$this->video->uid . '/'.$this->video->uid. '.gif';
    $result = Storage::disk('video-temp/'.$this->video->path);
    $ffmpeg = FFMpeg::create();
    $video = $ffmpeg->open($result);
    $video->gif(TimeCode::fromSeconds(2), new Dimension(640, 480), 3)->save($destination);

   $this->video->update([
       "image_gif" => $this->video->uid. '.gif',
   ]);
  
 }


    


    }

    


    and here is the error message [2021-08-27 12:47:33] [87] Failed : App \ Jobs \ ConvertImageGifFromVideo
And I would like to know if anyone has already encountered this kind of problem or if there is another way to write this code ?

    


  • grabbing hevc h265 stream using ffmpeg

    26 août 2021, par hendyman

    I have a problem when I try to grab h265 encoded video from ip camera using rtsp protocol.
I want to save stream from camera and i use https://github.com/sahilchaddha/node-rtsp-recorder/ to do this. Almost all works perfectly but output video has green bars and I don't know why.

    


    These are my parameters

    


    ChildProcess {
  _events: [Object: null prototype] {},
  _eventsCount: 0,
  _maxListeners: undefined,
  _closesNeeded: 1,
  _closesGot: 0,
  connected: false,
  signalCode: null,
  exitCode: null,
  killed: false,
  spawnfile: 'ffmpeg',
  _handle: Process {
    onexit: [Function],
    pid: 96408,
    [Symbol(owner_symbol)]: [Circular]
  },
  spawnargs: [
    'ffmpeg',
    '-i',
    'rtsp://[...]',
    '-vcodec',

  stdout: null,
  stderr: null,
  stdio: [ null, null, null ],
