Hello, i have this error for create a vidéo by glob with img. And i don't understand.

Notice: Trying to access array offset on value of type null

I use this code :

$audio = new Audio($this->getParameter('kernel.project_dir') . '/public/music/Ballad_of_the_Sneak.mp3');

    $process = $audio->getProcess();
    $process->addPreInputCommand('-framerate', '1/5');
    $process->addPreInputCommand('-pattern_type', 'glob');
    $process->addPreInputCommand('-i', glob($this->getParameter('kernel.project_dir') . "/public/glob/*.jpg"));
    $process->addCommand('-pix_fmt', 'yuv420p');
    $process->addCommand('-shortest', '');

    $output_format = new VideoFormat();
    $output_format->setVideoFrameRate('1/5')
                  ->setVideoDimensions(320, 240, true, true)
                  ->setAudioCodec('libfdk_aac')
                  ->setVideoCodec('mpeg4');

    $process = $audio->save('./homemade-video.mp4', $output_format);

Can you help me please ?
