android Q System Rotation problem

[aber]

Hi 

    We need to rotate 180° the system on android10. For reference https://community.nxp.com/t5/i-MX-Processors/Android-10-i-MX8MMini-g2d-rotation-issue/m-p/1187205#M1... , the system can rotate normally but the playing video cannot be rotated. Is there a good solution?

Tks!

Hello aber,

If the patch does not work for you?, sorry this will be add it to the next android, however You can try to modify "info.orientation = 0;" to other value, which shown below code:

for (const auto& hwConfig : getHwComposer().getConfigs(type)) {
        DisplayInfo info = DisplayInfo();

        float xdpi = hwConfig->getDpiX();
        float ydpi = hwConfig->getDpiY();

        if (type == DisplayDevice::DISPLAY_PRIMARY) {
            // The density of the device is provided by a build property
            float density = Density::getBuildDensity() / 160.0f;
            if (density == 0) {
                // the build doesn't provide a density -- this is wrong!
                // use xdpi instead
                ALOGE("ro.sf.lcd_density must be defined as a build property");
                density = xdpi / 160.0f;
            }
            if (Density::getEmuDensity()) {
                // if "qemu.sf.lcd_density" is specified, it overrides everything
                xdpi = ydpi = density = Density::getEmuDensity();
                density /= 160.0f;
            }
            info.density = density;

            // TODO: this needs to go away (currently needed only by webkit)
            sp<const DisplayDevice> hw(getDefaultDisplayDeviceLocked());
            info.orientation = hw ? hw->getOrientation() : 0;
        } else {
            // TODO: where should this value come from?
            static const int TV_DENSITY = 213;
            info.density = TV_DENSITY / 160.0f;
            info.orientation = 0;
        }

Hello  Bio_TICFSL

  My problem is still unresolved, and I found that the problem is similar to the one I encountered after searching the forum. Our default mipi resolution is 800x1280, which may be the cause of the problem。

Hi  Bio_TICFSL

Thank you for replying in your busy schedule. According to your prompt, I modified it and it didn't work. The video playback interface is the other way around.

info.orientation I am forced to modify it to 2 。The source code is based on Q10.0.0_2.5.0
