Зачем конвертировать M3U8 в AAC?
An .m3u8 (UTF-8 M3U Playlist / HLS manifest) is a text file listing segment URLs or local file paths - the actual audio lives in .ts or .m4s segment files. HLS audio is very commonly encoded in AAC (Advanced Audio Coding), making .aac a natural extraction target for offline playback or archiving.
Способы конвертации M3U8 в AAC

- The
.m3u8file itself contains no audio; the actual audio lives in.tsor.m4ssegment files that ffmpeg or yt-dlp fetches automatically. - Some HLS streams use time-limited, token-signed segment URLs - if the M3U8 was captured earlier and tokens have expired, you will get 403 errors and need a fresh URL.
- Encrypted HLS streams (marked
#EXT-X-KEY) require the decryption key; ffmpeg handles standard AES-128 automatically if the key URL is accessible.
