TMS320DM8148: Can VIP capture send out interrupt by lines?

Hi,

My customer wants to get interrupt by several lines instead of whole frame during VIP capture? Does the driver in RDK support such feature? If yes, would you pls kindly suggest how? Is the interrupt from VPDMA or VIP?

Thanks,

    Hi Chris,

    There is an feature of slice based capture in VIP driver, i guess it was added in DVR-RDK4.0 and later releases. 

    Essentially, it given callback after every n lines are captured along with the frame. This frame can be used as read only frame and once the complete frame is captured, it can dequeued. 

    You could go through VIP driver's header file to get idea about this feature.

    Rgds,
