通过ffmpeg将mp4文件转换为tta音频

我正在使用以下命令：

C:/ffmpeg/bin\ffmpeg.EXE "-i" "F:\laragon\www\sample\uploads\video\ba4ca90a71e0a05f67b9274827cc4f020c6ba95d.mp4" "-q" "4" "-strict" "experimental" "-threads" "1" "-vn" "F:\laragon\www\sample\uploads\audio\35b9611321a57726636a9a46c315ba395e3df6e8.tta"

但我收到了错误

    Unable to find a suitable output format for 'F:\laragon\www\sample\uploads\audio\35b9611321a57726636a9a46c315ba395e3df6e8.tta'
