J'essaie de créer une sortie HLS (fichier m3u8 + plusieurs fichiers .ts) à partir d'une liste de fichiers mp3 où les métadonnées mp3 id3 sont conservées dans la sortie HLS.Audio HLS avec métadonnées sur Mac à partir du répertoire de fichiers mp3?
J'ai essayé ffmpeg comme ceci:
ffmpeg -f concat -i list.txt -hls_init_time 2 -hls_time 2 out.m3u8
où list.txt contient:
file 01.mp3
file 02.mp3
file 03.mp3
file 04.mp3
file 05.mp3
file 06.mp3
file 07.mp3
file 08.mp3
file 09.mp3
file 10.mp3
Le résultat est un seul fichier out.m3u8 et un seul fichier out0.ts très volumineux. Je m'attendais à environ 1500 fichiers ts et un fichier m3u8 qui contient les 5 derniers fichiers ts.
Je suis complètement nouveau à ffmpeg et honnêtement je ne veux pas l'apprendre en profondeur maintenant.
Est-ce que quelqu'un sait comment faire cela avec ffmpeg ou autrement?

[hls @ 0x7fc50f01aa00] Frame rate very high for a muxer not efficiently supporting it.
Please consider specifying a lower framerate, a different muxer or -vsync 2
No pixel format specified, yuvj444p for H.264 encoding chosen.
Use -pix_fmt yuv420p for compatibility with outdated media players.

Également essayé avec un autre ensemble de mp3 aléatoires et ne fonctionne pas non plus. J'ai également essayé de transcoder en HLS à partir d'une URL de flux mp3 en direct et que * a * travaillé * dans la création de plusieurs fichiers ts comme défini dans les options. Dois-je d'abord convertir les fichiers MP3 d'entrée? – eagspoo
