Я пытаюсь создать вывод HLS (файл m3u8 + много .ts файлов) из списка mp3-файлов, где метаданные mp3 id3 сохранены в выводе HLS.Аудио HLS с метаданными на Mac из каталога mp3-файлов?
Я пытался FFmpeg, как это:
FFmpeg -f -i CONCAT list.txt -hls_init_time 2 -hls_time 2 out.m3u8
где list.txt содержит:
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
В результате получается один файл out.m3u8 и один очень большой файл out0.ts. Я ожидал около 1500 ts файлов и m3u8 файл, который содержит последние 5 ts файлов.
Я совершенно не знаком с ffmpeg, и, честно говоря, я не хочу углубленно изучать его.
Кто-нибудь знает, как это сделать с помощью ffmpeg или иным образом?

[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Use -pix_fmt yuv420p for compatibility with outdated media players.

Также попробовал другой набор случайных mp3-файлов, а также не работает. Я также пробовал транскодирование в HLS из живого mp3-потока url, и это * * работало при создании нескольких ts-файлов, как определено в опциях. Возможно, мне нужно сначала преобразовать входные mp3-файлы? – eagspoo
