Part Number: TDA4VM

While capturing the yuv frames through customised app_single_cam test app, we are getting 0xFF data in first 6-7 frames.
How to resolve this issue.

Thanks

    Hi Gokul,

    SDK : version 10.1

    Camera- OV camera

    Configuration- GMSL2 + app_single_cam.cfg

    No changes in demo 

    Viewing frames using 7yuv app

    Thanks.

    Hi Anant,

    Could you verify if the camera is giving the correct image frames from the starting.

    So you are saving the output directly from the capture node ?

    Could you check the capture statistics to check if there are any errors reported by csirx ?

    Hi Gokul,
    Yes camera is giving correct frames from starting.

    No, I am not saving output directly from capture node, capturing YUV output from ISP (VISS node)

    Checked the capture statistics, there are no errors reported by csrix.

    Regards,
    Anant.

    Could you describe your entire pipeline, and more info on the sensor, I thought the sensor gives yuv frames as output.

    is this sensor driver supported out of box or you have written your own driver.

    Could you dump the raw frames from the camera and view it externally to isolate its a csirx issue or vpac issue.
