你有两次二进制名称。简单地删除/usr/bin/ffmpeg：

sudo ffmpeg -y -i /home/alfanso/work/project/public/slides/file.mp4 -strict -2 -acodec vorbis -b:v 10k /home/alfanso/work/project/public/slides/file.ogg

第一个ffmpeg已经是您要运行的程序的名称。第二个作为参数传递给ffmpeg（因此程序ffmpeg已启动，其第一个参数设置为/usr/bin/ffmpeg）。

将mp4转换为ogg / usr / bin / ffmpeg时出错：参数无效
