用 ffmpeg 分割 flac 音轨

  • 772

我正在尝试将 flac 配乐拆分为多个文件，但它以Output file #0 does not contain any stream. 该文件实际上是在 ogg 容器中编码的 flac，但我对常规 flac 文件有同样的问题。

命令： ffmpeg.exe -i D:\_\RecManagerTests\103_1.flog -f segment -segment_time 30 -c copy D:\_\RecManagerTests\StreamingChunks/103_1_%03d.flog

输出：

    正如@Rotem 所建议的，目标扩展正在确定目标格式/编码，flog是一个组成的扩展（flac + ogg），例如使用它来flac解决问题：

    ffmpeg.exe -i source.flog -f segment -segment_time 30 -c copy target_%03d.flac
