    Hi,

    The root cause is that the VIP port cannot detect the video on the port.
    Please make sure that the parser configuration is done correct and the video is availalble at the video port.

    Note that the video size register is automatically updated by thr parser as soon as the video gets detected.
    The only software configuration needed for VIP is the parser config for this to happen.

    You may also find this utility helpful to find if the video is actually getting received at the VIP port
    git.ti.com/.../iodelay-config
    Generate(using -g option) a GPIO based probe script for the port you are using.
