继承人的命令:
ffmpeg -i videos/test.mp4 -c:v libvpx -level 216 -profile 0 -qmax 42 -qmin 10 -c:a libvorbis -f webm out.webm
我不断收到此错误:
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
这是完整的回复

有人知道发生了什么吗?我完全迷路了。我尝试了很多不同的命令。从 mp4 转换为 ogg 工作正常,我之前有 mp4 到 webm 工作,但我重新安装了 ffmpeg 以使 mp4 到 ogg 工作,现在我失去了我的 mp4 到 webm 转换。>.< 整个安装过程简直就是一场噩梦。有没有人有一个很好的centos安装ffmpeg的教程,适用于mp4 ogg和webm?我使用了来自 ffmpeg 网站的 centos tut,但它让我失望了。如果有人有任何想法可以为我指明正确的方向,我将不胜感激!
