我试图从mp3文件列表中创建HLS输出（m3u8文件+许多.ts文件），其中mp3 id3元数据保存在HLS输出中。
我一直在尝试ffmpeg：
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out.m3u8文件和一个非常大的out0.ts文件。我期待大约1500个ts文件和一个包含最后5个ts文件的m3u8文件。
我对ffmpeg来说是全新的，说实话，我现在不想深入学习它。
有没有人知道如何用ffmpeg或其他方法做到这一点？

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Use -pix_fmt yuv420p for compatibility with outdated media players.

您的MP3可能嵌入了封面艺术品。如果是，则将它们检测为视频流并用作用于分割的参考流。由于它只有一个框架，因此不需要创建额外的细分。
所以放弃封面艺术：
