这是我的命令:
ffmpeg -i /path/to/filename.wav -vn -acodec copy -ss 00:00:00 -t 00:13:00 /path/to/filename-0.wav
当我运行它时出现以下错误:
[NULL @ 0x55dfa3f27c80] Unable to find a suitable output format for '/path/to/filename-0.wav'
这是错误发生之前的输出:

Guessed Channel Layout for Input Stream #0.0 : mono
Input #0, wav, from '/path/to/filename.wav':
Duration: 00:14:07.60, bitrate: 128 kb/s
Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 8000 Hz, mono, s16, 128 kb/s
无法剪切 WAV 文件吗?将 WAV 文件转换为 MP3 是我唯一的选择吗?
答案1
尝试通过添加来明确告诉它输出到 wav-f wav
ffmpeg -i /path/to/filename.wav -vn -acodec copy -ss 00:00:00 -t 00:13:00 /path/to/filename-0.wav
