在Android上使用FFmpeg合并mp3文件 [英] Merge mp3 files using FFmpeg on Android

问题描述

  ffmpeg -iconcat：/ storage / emulated / 0 / Recordings / oneone.mp3 | /storage/emulated/0/Recordings/twone.mp3-c copy /storage/emulated/0/Recordings/concated.mp3 
  

但收到此错误：

 concat：/ storage / emulated / 0 / Recordings / oneone.mp3 | /storage/emulated/0/Recordings/twone.mp3：没有这样的文件或目录
  

即使这两个文件都存在于目录中。我已经根据以下文档编写了这个命令： https://trac.ffmpeg.org/wiki/ Concatenate＃protocol

我该如何解决？请帮助我。

解决方案

您确定您对设备有读写权限吗？因为从我的经验，下面的命令工作完全正常。

  ffmpeg -iconcat：/sdcard/test1.mp3 | /sdcard/test2.mp3-acodec copy / sdcard / output.mp3 
  

I am trying to merge two mp3 files using this command:

ffmpeg -i "concat:/storage/emulated/0/Recordings/oneone.mp3|/storage/emulated/0/Recordings/twone.mp3" -c copy /storage/emulated/0/Recordings/concated.mp3

but get this error:

"concat:/storage/emulated/0/Recordings/oneone.mp3|/storage/emulated/0/Recordings/twone.mp3": No such file or directory

Even though the both files exist in the directory. I have written this command according to the documentation: https://trac.ffmpeg.org/wiki/Concatenate#protocol

How do I fix this? Please help me.

解决方案

Are you sure you have read and write permissions on the device? Because from my experience the below command works perfectly fine.

 ffmpeg -i "concat:/sdcard/test1.mp3|/sdcard/test2.mp3" -acodec copy /sdcard/output.mp3
