-i ts_links.txt : Tells aria2c to read the list of target URLs from your input text file.
Many streaming platforms protect M3U8 streams with custom user agents, cookies, or authorization tokens. If aria2c returns a 403 Forbidden error, pass the exact headers required by the source server:
Select-String -Path .\playlist.m3u8 -Pattern '^#' -NotMatch | Select-Object -ExpandProperty Line > urls.txt Use code with caution. Handling Relative URLs
Now unleash aria2c:
:Once all .ts segments are in your folder, use FFmpeg to combine them into one MP4 file. ffmpeg -i your_file.m3u8 -c copy output.mp4 Use code with caution. Copied to clipboard Why use FFmpeg instead?
Are the video segments inside your M3U8 file (starting with http) or relative local paths ?
Once the process finishes, you can safely delete the urls.txt , concat.txt , and all individual .ts chunks. Your final, high-quality output.mp4 is ready. Dealing with Complex Configurations 1. Master Playlists (Variant Streams) aria2c m3u8
Because aria2c expects direct file links, trying to run aria2c video.m3u8 will only download the tiny text file itself, not the actual video segments. To successfully download the stream, you must follow a three-step pipeline: the M3U8 playlist. Extract all the segment URLs into a plain text file.
Practical Commands & Options (concise)
ffmpeg -f concat -safe 0 -i concat_list.txt -c copy final_output.mp4 Use code with caution. Method B: Binary Copy Concatenation (Quick & Dirty) -i ts_links
Pass your browser’s User-Agent and Referer string directly into your aria2c command:
ffmpeg -protocol_whitelist file,http,https,tcp,tls,crypto \ -i "stream.m3u8" \ -c copy \ -f mp4 \ -download_protocol "http,https" \ -downloader "./aria2_downloader.sh" \ output.mp4
