When I click The Retrieve Data button,it shows success,but it never play back.you can see the picture bellow the details.

When I get the device bitstream, I parse out the first frame data, and pay the frame data to milestone in the readdata() interface. In principle, I should enter the readdata() interface again, but directly enter the destroy() interface, release the relevant resources, and then the client display is completed. Why is this happening?

It is likely that either the contents of the frame header or one of the goto methods returns something that indicates to the system that no more data is available. Please compare your code in the playback manager to the one of the demo driver.

Also please make sure that you select a period for retrieval.

goto methods returns something that indicates to the system that no more data is available.

There is no goto method, can you be more specific?

Sorry I meant MoveTo and Navigate
