TDA4VM: frame rate loss

xie jc
Expert 2180 points
Part Number: TDA4VM

Dear TI experts,

    Is there a register to monitor the frame rate of the camera received by the SOC？

    We found that the frame rate was 5~6 frames lost in the SDK8.4 when we run surround view test case.

    We can get the complete 30 frames of signal through the oscilloscope, but the print of soc is only 24 frames.

   

Regards.

    Hi xie jc,

    There is no register to check for the frame rate and most likely in your case, some other node is dropping the frames or taking more time, which is why graph is running slower. Please check your individual node performance in the graph.

    Actually, I only have one capture node now.

    Can you tell me how to test node performance？

    Regards.

    Hi xie jc,

    Typically, for vision apps usecase, when we press 'p' on the uart console when running the usecase, it prints complete statistics.. which gives node performance as well as complete graph performance.. Can you please get this performance and see if capture is running at 30fps? Also in the application, are you running anything else which can block enqueue/dequeue operations of the capture node? 

    Regards,
