Installation

• This package is available on packagist

    composer require lakshmaji/thumbnail

• Add the Service Provider to providers array

  Lakshmaji\Thumbnail\ThumbnailServiceProvider::class,

• Add the Facade to aliases array

  'Thumbnail' => Lakshmaji\Thumbnail\Facade\Thumbnail::class,

• Try updating the application with composer (dependencies but not mandatory )

  composer update

Configurations

• Publish the configuration file , this will publish thumbnail.php file to your application config directory.

    php artisan vendor:publish

• Configure the required FFMpeg configurations.
  • FFMpeg will autodetect ffmpeg and ffprobe binaries. If you want to give binary paths explicitly, you can configure them in .env file.
  • You can specify the output image dimensions in .env file. (dimensions array parameters)
  • Add watermark or playback button url to watermark arry aviable in thumbnail.php
  • Or you can configure them from laravel .env file, the sample watermark resource configurations in .env file
    ```bash

    Thumbnail image dimensions

    THUMBNAIL_IMAGE_WIDTH = 320
    THUMBNAIL_IMAGE_HEIGHT = 240

Watermark image

WATERMARK_IMAGE = true
WATERMARK_PATH = /var/www/html/thumb/storage/watermark/p.png

Custom FFMPEG binaries path

FFMPEG_BINARIES = true
FFMPEG_PATH = /opt/local/ffmpeg/bin/ffmpeg
FFPROBE_PATH = /opt/local/ffmpeg/bin/ffprobe
FFMPEG_TIMEOUT = 3600
FFMPEG_THREADS = 12

This ensures that all the generated thumbnails with watermarks are having fixed dimensions

class ThumbnailTest extends AnotherClass
{
  public function testThumbnail()
  {
    // get file from input data
    $file             = $this->request->file('file');
    // get file type
    $extension_type   = $file->getClientMimeType();
    // set storage path to store the file (actual video)
    $destination_path = storage_path().'/uploads';
    // get file extension

      // set the thumbnail image "palyback" video button
      $water_mark       = storage_path().'/watermark/p.png';
      // get video length and process it
      // assign the value to time_to_image (which will get screenshot of video at that specified seconds)
      $time_to_image    = floor(($data['video_length'])/2);
      $thumbnail_status = Thumbnail::getThumbnail($video_path,$thumbnail_path,$thumbnail_image,$time_to_image);
      if($thumbnail_status)
      {
        echo "Thumbnail generated";
      }
      else

        echo "thumbnail generation has failed";
      }
    }
  }
}
// end of class ThumbnailTest
// end of file ThumbnailTest.php

METHOD

$thumbnail_status = Thumbnail::getThumbnail(<VIDEO_SOURCE_DIRECTORY>,<THUMBNAIL_STORAGE_DIRECTORY>,<THUMBNAIL_NAME>);

$thumbnail_status = Thumbnail::getThumbnail(<VIDEO_SOURCE_DIRECTORY>,<THUMBNAIL_STORAGE_DIRECTORY>,<THUMBNAIL_NAME>,<TIME_TO_TAKE_SCREENSHOT>);

thumbnail image| optional|
