Hi,

             I am following below link to up the LCD (480X272 sharp)

http://processors.wiki.ti.com/index.php/TI81XX_PSP_VPSS_Video_Driver_User_Guide.

It is able to generate the clk, hsync, vsync and I am using the test application from the source

/TI81XX-LINUX-PSP-04.04.00.02/src/examples/video/saFbdevDisplay

log for the application run is

root@dm814x-evm:~/lcd# ./saFbdevDisplay

Fix Screen Info:
----------------
Line Length - 1440
Physical Address = 8ce00000
Buffer Length = 25165824

Var Screen Info:
----------------
Xres - 480
Yres - 272
Xres Virtual - 480
Yres Virtual - 272
Bits Per Pixel - 24
Pixel Clk - 111111
Rotation -0

but nothing is getting displayed on to the LCD screen.

please let me know if I am missing any thing.

Thanks,

Sudheer.

    Hi,

                  Now I am able to run the matrix-gui-e application and it is able to display ti matrix menu and its content.

    Please let me know the application to display image, play video on LCD using the fbo interface.

    Thanks,

    Sudheer.

    Hello,

    You could check OMX decode_display demo.

    To get the graphics plane over the fbdev0, the command to be used is as follows:
    ./decode_display_a8host_debug.xv5T -i ./sample.h264 -w 1920 -h 1080 -f 60 –d 1 -g 1

    -d 1 for LCD display

    -g 1 for graphics enable.

    Best Regards,

    Margarita

    Hi,

               I have tried the command but there was no display on the lcd.

    Do we have a application which uses the /dev/fb0 interface

    Command log:

    Hello,

    Could you provide the steps that you are executing before to start the decode_display demo?

    By default this is the what is using when the -d 1 is set :

    /*LCD display specific configurations, these parameters come from */
    /*the LCD display datasheet */
    #define DISPLAY_WIDTH         (800)
    #define DISPLAY_HEIGHT        (480)
    #define LCD_PIXEL_CLOCK   (33500)
    #define LCD_H_FRONT_PORCH (164)
    #define LCD_H_BACK_PORCH  (89)
    #define LCD_H_SYNC_LENGTH (10)
    #define LCD_V_FRONT_PORCH (10)
    #define LCD_V_BACK_PORCH  (23)
    #define LCD_V_SYNC_LENGTH (10)

    Have you try to change this in /EZSDK/component-sources/omx_05_02_00_48/examples/ti/omx/demos/decode_display/src/dm814x

    platform_utils.h

    Hello,

    Try first to decode_display  the video without the audio.

    The pipeline should be something like:

    gst-launch filesrc location=/..../  ! qtdemux ! h264parse ! omx_h264dec ! omx_scaler ! v4l2sink device=/dev/video2 userpointer=false  min-queued-bufs=2

    Hi Margarita,

                                    I am trying the suggested script for displaying the video, there is some issue with the input source .h264 file and trying to down load a proper .h264 file.                               

                                    How can I change the LCD display channel to TV-out display. There is some script change_display.sh but there is no code in this script which will change the display to TV out. Please help to display the content on to TV out.

    Thanks,

    Sudheer.
