我根据以下推荐选择了 ffmpeg 作为工具:如何批量将 MP3 系列转换为 M4B。
我从以下网址下载了适用于 Windows 的静态版本http://ffmpeg.zeranoe.com/builds/。
当我尝试将 4 个 mp3 文件合并为 1 个 m4b 文件时,出现如下错误。我该怎么办?没错,ffmpeg 支持 m4b 文件....
我跑了:
C:\EBC>ffmpeg -i "concat:65.mp3|airbus.mp3|alcoholabuse.mp3|allergies.mp3" -c libfdk_aac -b:a 64k EBC.m4b

答案1
.m4b
无法被 ffmpeg 识别。
两种解决方案:
- 使用
-f mp4
强制 MP4 格式输出,或 - 用作
.m4a
文件名并稍后手动重命名
