试了 --scenecut 80 160 320 500 1000 (500 和 1000 没看出区别来 估计浪费了)
另外 -i 在 --scenecut 1000的情况下 试了 6 12 24 怎么反而是24 I帧最多呢 不懂了
-i的描述
This is the minimum GOP (Group Of Pictures) value. This specifies the minimum number of frames allowed before a new IDR frame and GOP is forced. If a scene change happens within the --min-keyint value, it will simply code the first frame of the scene change as an I frame and prevent it from starting a new GOP.
另外 关于VP7的CPU消耗问题 即便调节到30% 播放时候照样还是在50-70% 光这点VP7就败了
