Vishal Posted September 13, 2018 Share Posted September 13, 2018 I am currently working on a Development Board based on RK3288. We are using Rockchip kernel as mentioned here https://github.com/rockchip-linux/kernel This uses libdrm (DRI) for its rendering purposes. But it has limitations. Only one CRTC is connected out of 2. It provides 8 planes, out of which only 4 are available for the working CRTC, out of which user available OVERLAY planes are only 2, and out of which only 1 Plane supports NV12 rendering. I need to show 2-4 videos simultaneously, can anyone help me here on how to procure more planes, particularly NV12 compatible OVERLAY type, that can be connected to the working CRTC?

chwe Posted September 13, 2018 Share Posted September 13, 2018 keep in mind, technical support sub-forums are only for boards we actually support --> moved to p2p tech support. @JMCCs work might be a starter for you... Link to comment Share on other sites More sharing options...
