- Improved the upload/edit flow to auto-grab thumbnails.
What changed: Added shared thumbnail helpers in [includes/db.php](/Users/tyemeclifford/Documents/GH/mediaplayer/includes/db.php):YouTube direct thumbnails Dailymotion direct thumbnails oEmbed thumbnails for Vimeo, Wistia, TikTok, SoundCloud, Spotify, etc. optional first-frame thumbnail generation for local uploads when ffmpeg is installed Added an “Auto-grab thumbnail” checkbox to [admin/add.php](/Users/tyemeclifford/Documents/GH/mediaplayer/admin/add.php) and [admin/edit.php](/Users/tyemeclifford/Documents/GH/mediaplayer/admin/edit.php). Reused the new shared downloader in [admin/youtube_import.php](/Users/tyemeclifford/Documents/GH/mediaplayer/admin/youtube_import.php). Documented the behavior in [README.md](/Users/tyemeclifford/Documents/GH/mediaplayer/README.md).
