-downloader_options "-j 16 -x 16 -s 16" : Passes high-speed optimization flags to aria2c. -j 16 : Allows up to 16 concurrent downloads. -x 16 : Allows up to 16 connections per server.
Aria2c's parallel download capability is its killer feature for m3u8 streams. Traditional downloaders fetch video segments one at a time, sequentially. Aria2c can simultaneously download multiple segments using multiple connections per server. This approach can reduce total download time by 50-80% depending on your network conditions and the server's configuration.
Once you have the m3u8 URL, the first step is downloading the playlist file itself:
ffmpeg -i "URL.m3u8" -downloader aria2c -downloader_options "--user-agent='Custom' --header='Referer: URL'" -c copy out.mp4 aria2c -i segments.txt -j 16 -x 16
aria2c --header="Cookie: session_id=abc123; user_token=xyz789" "https://example.com/video.m3u8"
aria2c --max-download-limit=5M -i ts_urls.txt
It only downloads the files; it does not automatically merge them into a single video file. Method 2: High-Speed Parallel Download ( -P -Z )
The key to success lies in understanding the underlying HLS protocol, properly extracting m3u8 URLs, using appropriate aria2c parameters for your network conditions, and correctly handling any encryption or authentication requirements. With practice, you'll develop workflows that can download even the most complex streams efficiently.
