Problem displaying 720x480 ( NTSC ) image with OSD0 on DM365

amit pandya

Hi all,

when i try to display 720x480 (NTSC ) image using the OSD0 on DM365 ,I am getting the output image is been cropped in all directions,means Image is overshooting the display ( TV ) boundaries.

I am using following two APis to set the node and output.

change_sysfs_attrib(ATTRIB_OUTPUT, DISPLAY_INTERFACE_COMPONENT)

change_sysfs_attrib(ATTRIB_MODE, DISPLAY_MODE_NTSC)

I am using Directfb for dispalying the image.

Can anyone tell me what could be the problem? why image is been cropped instead of fitting exacly in the TV screen.

Amit,

We have faced the same issue on the Dm355 as well. We were using a VID0 and see that the Image is over-shooting the TV Boundary.

Ravi

Hi Ravindra.

For which resolution you got the same problem?

what fix you have made to solve the problem?

Have you used any other library ( say directfb .. ) to display on tv or the normal fbdev code to display?

Have you faced similar over shooting problem for HD ( 720P & 1080i ) display also?

Thanks.

Amit,

We have not yet solved this problem. It is just that we have also observed the same issue on the Dm355 Leopard board as well.

Ravi
