DM8168使用swms合成4路视频,如果4路视频进swms前和在swms里都是一个分辨率,swms的scalar instance有硬件消耗么?



HI,如题。

4路960*540P30视频,Merge后送给swms,swms输出1080P30视频,4路视频在1080P30合成画面中是田字格4分割,也就是进swms前在swms中没有视频分辨率和帧率的变化,那如果swms分配的scalar是SC5,SC5是否有硬件消耗?比如就像普通视频缩放一样,A分辨率帧率缩小到B分辨率帧率,就按照输入输出中最大的分辨率帧率在计算Scalar硬件消耗。我想,因为进swms前就已经缩放好了,是不是SWMS中scalar instance不再有硬件消耗,或者消耗很少。

请TIer帮忙指正问题。谢谢!
