Hi,every nxp experts
I use the imxv4l2src and appsink plugins of gstreamer to get the frame of the MIPI camera(OV5640),then i use QML+OpenGL to render the video and glsl to convert the pix format(YUV->RGB).when i run the program on the LVDS(1280x800),the rendering performance is very well,but when running the same program on the dual display(1920x1080@60,HDMI+LVDS),there is only about 15fps and 300ms rendering delay.
so how can i improve the performance when rendering on dual display
And is it the imx6q board is qualified the high rendering performance of dual display.
The bsp version is Linux4.9.88+Qt5.9.4+xwayland
Hi 747550962
in general video performance depends on internal bus loading and use case.
One can try to tweak IPUs (QoS) priority using IOMUXC_GPR6, described
in sect.36.4.7 GPR (IOMUXC_GPR6) i.MX 6Dual/6Quad Applications Processor Reference Manual
One can also try latest linux releases described on
Best regards
