      V853 创建三路编码+一路VO,MP4+JPEG+RTSP,分辨率都一致,在VIDEV=0上创建三路VIPP对应三路编码,VIDEV=4上创建一路VIPP对应VO,VO上叠加Qt菜单,现在想把Qt菜单也叠加到三路编码上,实现编码和VO的图像效果一致,当前SDK只能一路一路VENC叠加,效率极低,有什么最优的办法吗?

        可以在DE层面优化,不在VENC上优化

          @whycanservice V853 VO上叠加QT后,要送编码+RTSP,这个怎么操作好?测试发现DE回写速度很慢,谢谢。

            是否可以创建一路VirChn,同时绑定三路编码(MP4+jpeg+rtsp),然后在VI上叠Qt的OSD?是OSD效率高,还是采用非绑定模式,先GetCSIFrame后做G2D处理,再send到三路编码的效率高?
