当我从命令行运行它时一切都很好
ffmpeg -i input.mp4 -f mp3 -ab 320000 -vn output.mp3
但是当我从 python 调用相同的
subprocess.call(['ffmpeg', '-i', 'input.mp4', '-f', 'mp3', '-ab', '320000', '-vn', 'output.mp3'])
几秒钟转换后，我收到此错误
[aac @ 0x7fb3d803e000] decode_band_types: Input buffer exhausted before
END element found
Error while decoding stream #0:1: Invalid data found when processing
input

有任何想法吗？
