在Mac上从mp3文件目录获取带有元数据的音频HLS？

[英]Audio HLS with metadata on Mac from directory of mp3 files?

问题描述

我正在尝试从mp3文件列表创建HLS输出（m3u8文件+许多.ts文件），其中mp3 id3元数据保留在HLS输出中。

我一直在尝试ffmpeg这样的：

ffmpeg -f concat -i list.txt -hls_init_time 2 -hls_time 2 out.m3u8

其中list.txt包含： 

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

结果是一个单独的out.m3u8文件和一个非常大的out0.ts文件。 我期望大约1500 ts文件和一个包含最后5 ts文件的m3u8文件。

我是ffmpeg的新手，老实说，我现在不想深入学习它。

有谁知道如何用ffmpeg或其他方式做到这一点？

您的MP3可能嵌入了封面。 如果是这样，则将其检测为视频流并用作分割的参考流。 由于只有一帧，因此无需创建其他段。

因此，放弃封面： 

ffmpeg -f concat -i list.txt -vn -hls_init_time 2 -hls_time 2 out.m3u8
