VOE provider returns HLS streams (.m3u8) which previously used yt-dlp's
native HLS downloader. That downloader does not report downloaded_bytes/
total_bytes in progress hooks, causing only 0% and 100% to ever show on
the queue page. Explicitly set 'downloader: ffmpeg' so progress updates
with actual byte counts are broadcast, enabling intermediate percentages
(25%, 50%, 75%, etc.) to display correctly.
