TDA4VM: enable writing LDC output fail

Part Number: TDA4VM

Hi ,

I use TDA4 evaluation board, SDK v8.04 and a IMX390 camera.

I want to get LDC image output file.

I tried the vx_app_multi_cam.out.

The configuration parameter "en_out_ldc_write" change from 0 to 1.

Following is my configuration file.

app_multi_cam_ldc_write.cfg

The screen freezes after run vx_app_multi_cam.out.

No LDC image file output after key in "s" command.

Following is the log.

    Hi Jason,

    Thank you for pointing this out. This is a bug in the software.

    I have filed an internal JIRA for the same.
    Putting the JIRA link here for TI's internal reference.

    https://jira.itg.ti.com/browse/ADASVISION-5758

    Could you please let me know your usecase here?
    In the software, the viss output write and capture output write are working as expected.

    Could you tell me the reason to dump the LDC output?

    A suggestion here would be to connect to a display and verified the LDC output.

    Regards,
    Nikhil

    Hi Nikhil,

    My FOV120 camera have distortion.
    I tried to generate lookup table for my FOV120 camera.
    In order to remove distortion.
    So, I need to check the LDC output when use the new lookup table.
    I found another method to get LDC output.
    I used the "run_app_single_cam.sh" to get LDC output.
    Thank you about your reply.

    -Jason

    Hi Jason,

    Yes, LDC LUT can also be checked in the single camera or any other application. Once checked, you would reuse it in any other application..
