echo "Merging segments into $OUTPUT_NAME.mp4..."
If you want to use aria2c directly, you must first extract the segment URLs from the M3U8 file and feed them into a text file.
echo Downloading playlist: %M3U8_URL% set "PLAYLIST_FILE=temp_playlist.m3u8" curl -s -o "%PLAYLIST_FILE%" "%M3U8_URL%" aria2c m3u8
I tested a 2-hour 1080p stream (500 .ts chunks, ~50 MB total):
aria2c -o playlist.m3u8 "https://example.com/stream/video.m3u8" echo "Merging segments into $OUTPUT_NAME
aria2c cannot natively parse an M3U8 playlist file directly from a live URL link to download segments sequentially. It requires a plain text file containing a list of direct URLs.

For macOS, the easiest method is by using Homebrew .
Open your web browser (Chrome, Firefox, or Edge) and navigate to the video page.
