ffmpeg('C:/path/to/list.txt').mergeToFile('C:/path/to/out.mp4', 'C:/path/to/temp');
list.txt:
file 'C:/path/to/chunk01.ts'
file 'C:/path/to/chunk02.ts'
file 'C:/path/to/chunk03.ts'
file 'C:/path/to/chunk04.ts'
注意：绝对路径和相对路径我都试过了，结果一样。
预期结果
C:/path/to/out.mp4 处的视频文件与 list.txt 中的 4 个文件相匹配，首尾相连。
观测结果
C:/path/to/out.mp4 处的空文件，持续时间为 0，大小仅为 15kB。没有抛出任何错误。
这是我要复制的命令（它按预期工作，相对路径在 list.txt 中）：
C:/path/to> ffmpeg -f concat -i list.txt -c copy out.ts
标准输出和标准错误
标准输出为空。 stderr 复制如下（修改文件名以匹配上面的文件名）：
