我正在尝试使用 ffmpeg 中的 arnndn 过滤器对音频剪辑进行降噪：
ffmpeg -i audio.aac -af 'arnndn=m=mp.rnnn' audio_out.aac
但我一直收到错误
[AVFilterGraph @ 0x5928550d3e80] Error initializing filters Error reinitializing filters! Failed to inject frame into filter network: Invalid data found when processing input
我尝试了不同的输入文件。我需要特殊的依赖项才能使用 arnndn 吗？
我正在使用这个 ffmpeg 版本：
