TMS320DM368: Frame loss in dual/triple stream

Part Number: TMS320DM368

Hi,

We are developing a camera using the DM368 DaVinci Video Processor and AR0330 sensor. The software platform used is IPNC RDK 5.1. We are observing  frame loss while streaming video in multiple stream mode. Lost frame count is increasing continuously and is verified with VLC (no issue observed with single stream).  Following are the video configurations:-

Primary stream configuration:-                                                Secondary stream configuration:-

Compression - H264                                                                 Compression - H264

Resolution - 1080p                                                                     Resolution - D1

FPS - 25                                                                                        FPS - 20

Bitrate - 4Mbps                                                                            Bitrate - 1Mbps

Primary stream FPS is reduced with above configuration.  So continuous break is observed in video and bebug print coming  in VLC is "core video output debug: picture might be displayed late (missing 6 ms)"

Also attaching video having frame loss issue when camera is connected in NVR. Issue is frequent while streaming in NVR. Kindly give your suggestions.
