我正在使用一個(gè)名為pascalbaljetmedia/laravel-ffmpeg并想要?jiǎng)?chuàng)建一個(gè)用于視頻流的 HLS 播放列表。但首先我想檢查視頻比特率或?qū)挾?高度，看看它是否是 4k、1080、720 等。那么我如何計(jì)算視頻比特率及其尺寸？...這是獲取視頻信息后我想做的事情：$video = FFMpeg::fromDisk('videos')                ->open('original_video.mp4')                ->exportForHLS();$resolutions = [];//check if we can make 4k versionif ( ( $bitrate >= 14000 )  ||  ( $width >= 3840 && $height >= 2160 ) ) {     // Then it's a 4k video    // We make a 4k version of HLS    $resolutions[] = ['q' => 14000, 'size' => [ 'w' => 3840, 'h' => 2160]];}//check if we can make HD versionif(  ( $bitrate >= 5800 )  ||  ( $width >= 1920 && $height >= 1080 )  ){     // Then it's a HD video    // We make a HD version of HLS    $resolutions[] = ['q' => 5800, 'size' => [ 'w' => 1920, 'h' => 1080]];} //Lastly we loop through and add formartsforeach($resolutions as $resolution){    $video->addFormat($resolution['q'], function($media) {        $media->addFilter('scale='. $resolution['size']['w].':'. $resolution['size']['h]);    });}$video->save('video_name.m3u8');有什么幫助嗎？
