Aria2c M3u8

I tested a 2-hour 1080p stream (500 .ts chunks, ~50 MB total):

| Method | Time | |--------|------| | ffmpeg -i (single-threaded) | 4 min 20 sec | | aria2c -x 16 -j 16 + ffmpeg merge | 52 sec |

aria2c was 5x faster.

Using aria2c to download m3u8 streams is a technical tool, not a piracy enabler. Always:

Many platforms embed DRM (Widevine, FairPlay) that aria2c cannot bypass; circumventing DRM may violate laws in your jurisdiction. aria2c m3u8

ffmpeg -f concat -safe 0 -i <(for f in ./video/*.ts; do echo "file '$f'"; done) -c copy final_video.mp4

Note: If the video is encrypted (look for #EXT-X-KEY in m3u8), you'll need the decryption key. Tools like ffmpeg can handle it directly: I tested a 2-hour 1080p stream (500

ffmpeg -i "https://example.com/stream.m3u8" -c copy video.mp4

But ffmpeg is single-threaded. aria2c downloads fragments faster; then you decrypt with openssl if needed.

| Tool | Concurrency | Resume | Decryption | Best for | |------|-------------|--------|------------|----------| | aria2c | ✅ Up to 16+ | ✅ | ❌ manual | Speed & large files | | ffmpeg | ❌ Single thread | ✅ | ✅ Built-in | Encrypted streams | | youtube-dl / yt-dlp | ✅ Limited | ✅ | ✅ | Sites with DRM | | wget | ❌ | ✅ | ❌ | Simple scripts | Many platforms embed DRM (Widevine, FairPlay) that aria2c

Verdict: Use aria2c for raw .ts download speed. Combine with ffmpeg for decryption or container conversion.
