High quality camera sensors usually output only raw RGB(Bayer pattern) data.

But FSL camera HAL can only preview HAL_PIXEL_FORMAT_YCbCr_420_SP format, which is supported by IPU and VPU both(see below codes in BSP).

 

void DeviceAdapter::setPreviewPixelFormat()

{

    int vpuFormats[MAX_VPU_SUPPORT_FORMAT];

    memset(vpuFormats, 0, sizeof(vpuFormats));

    int ret = mMetadaManager->getSupportedRecordingFormat(&vpuFormats[0],

                                    MAX_VPU_SUPPORT_FORMAT);

    if (ret != NO_ERROR) {

        FLOGE("getSupportedRecordingFormat failed");

        mPreviewPixelFormat = HAL_PIXEL_FORMAT_YCbCr_420_SP;

        return;

    }

    mPreviewPixelFormat = getMatchFormat(vpuFormats, MAX_VPU_SUPPORT_FORMAT,

                          mAvailableFormats, MAX_SENSOR_FORMAT);

}

 

How to modify the camera HALL to preview this type of sensor data?
