• Laravel php timelapse an UploadedFile video element, without saving it as a file

  24 août 2022, par The Blind Hawk

  I want to be able to change the frame rate of a video from 0.05fps to 3fps.
  
I receive the video as an Illuminate\Http\UploadedFile element, with mp4 format, how do I speed up its frame rate before sending it via email ?
  
The video is 25 minutes long, it should become 25 seconds long after changing the frame rate.
  
Is there a way to change the fps without saving the element as a File ?
  
I was planning to use the ffmpeg repository here but it requires me to save both the initial file, and the second file after changing the fps.

  
This is my code :

  


  <?php

namespace Server\Mail;

use Carbon\Carbon;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Http\UploadedFile;

class TimeLapse extends Mailable
{
    use Queueable, SerializesModels;

    public UploadedFile $video;

    public bool $is_timelapsed;

    public string $format;

    /**
     * Create a new message instance.
     */
    public function __construct(
        UploadedFile $video, 
        bool $is_timelapsed, 
        string $format
    ){
        $this->video = $video;
        $this->is_timelapsed = $is_timelapsed;
        $this->format = $format;
    }

    private function timelapse(){
        // here I want to change $video element's fps from 0.05 to 3
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        if ( !$is_timelapsed ) { timelapse(); }

        $this->subject('message')
                    ->text('emails.timelapse');

        $this->attach($this->video, [
            'as' => 'sample'.$format,
            'mime' => 'video/'.$format,
        ]);

        return $this;
    }
}
