Unable to find a suitable output format for 'opus'
FFmpeg v4.14 执行如下命令，会报错，为何？ffmpeg -y -v warning -i <infile> -vn -acodec libopus opus <outfile.opus> & pause Unable to find a suitable output format for 'opus'opus: Invalid argument
不删减任何输出，执行一下ffmpeg把输出贴出来看一下 本帖最后由 mmlion 于 2020-5-13 02:51 编辑
顺便，希望能解决中文名乱码问题，烦人！

Unable to find a suitable output format for 'opus'
opus: Invalid argument 我以为MP3支持不好，找了一首音乐wav，还是报错：Guessed Channel Layout for Input Stream #0.0 : stereo

Unable to find a suitable output format for 'opus'
opus: Invalid argument 这个看上去更像是不支持opus的格式输出，可以尝试输出webm的格式，音频codec是opus
