How to use encodedecode example as LCD display

Hi all,

We want to use encodedecode which is in dvsdk_2_00_00_22\dvsdk_demos_2_00_00_07\dm6446 as LCD display. We had been verifed to display as COMPOSITE. How can we use encodedecode as LCD display. We have tried it at the following.

const Display_Attrs Display_Attrs_DM6446_LOGICPD_ATTR_DEFAULT = { //OSD1
    1,
    Display_Std_FBDEV,
    VideoStd_LCD_1024_768, // this is included on our source(Dmai, logicpd_encode.c).
    Display_Output_LCD,
    "/dev/fb/2",
    0
};

const Display_Attrs Display_Attrs_DM6446_LOGICPD_OSD_DEFAULT = { // OSD0
    2,
    Display_Std_FBDEV,
    VideoStd_LCD_1024_768,
    Display_Output_LCD,
    "/dev/fb/0",
    0
};

const Display_Attrs Display_Attrs_DM6446_LOGICPD_VID_DEFAULT = { // capture
    3,
    Display_Std_V4L2,
    VideoStd_LCD_1024_768,
    Display_Output_LCD,
    "/dev/video3",
    0
};

But, It isn't work. So, we want to know what is changed in source or what is important points. If it is necessary to know any information about it, request me please.

Best regard.

    I believe that if you run encodedecode with the -h (help) option, it will give you  options for routing output to composite (analog), or component (digital interface) video outputs.  Optionally, you can read encodedecode.txt file instead of using help option.

    Thank you for your reply.

    I have some questions.

    If we are using Display_Output_COMPONENT for digital interface, what is Display_Output_LCD? Is this analog interface?

    If we want to use 800x600 LCD, Do we have to add this resolution into device driver sources and so on?

    Thanks and BR.

    And,  We have verifed 640x480 with just back screen. we changed something for this as the follwoing.

    (1) We had tried OSD.

    (2) "ERR: Png_show() not supporting image color format" was launched. what is mean?

    (3) "[Display] Failed to detemine video display format on Invalid argument" was launched, I don't understand what is mean? Why is "Invalid argument"? 

     

    Would you like give me some advice?

    Thanks and BR.
