Many premium streaming platforms protect their HLS content using AES-128 encryption. If the playlist file includes a #EXT-X-KEY tag specifying a URI for an encryption key, FFmpeg can decrypt the segments automatically on two conditions: The encryption key is using standard AES-128.
-i : Specifies the input URL of the M3U8 playlist. Always wrap the URL in quotes to avoid shell parsing errors caused by ampersands or question marks.
Segmented streams often contain timestamp discontinuities that lead to drifting audio or frozen video frames during playback.
Master M3U8 files often contain multiple variant streams tailored for different bandwidth conditions (e.g., 480p, 720p, 1080p). By default, FFmpeg selects the highest bitrate variant. You can manually map specific video and audio streams using the -map flag.
