This problem occurs in DeepStream 5 only, and not occur in DeepStream 4 In the reference application deepstream_test5_app, i tried to use the function callback overlay_graphics() to draw custom overlays. In that function I map the gestreamer input buffer in this sequence: gst_buffer_map() NvBufSu…

There is no update from you for a period, assuming this is not an issue any more. Hence we are closing this topic. If need further support, please open a new one. Thanks Can you repro your issue with pure ds-test5?

Hey Customer, Could you fill the setup info firstly?

• Hardware Platform (Jetson / GPU) - Xavier NX • DeepStream Version - 5.0 • JetPack Version (valid for Jetson only) - 4.4 DP • TensorRT Version - 7.0 • NVIDIA GPU Driver Version (valid for GPU only)

Thanks, we should support both RGBA and NV12, have you checked dsexample → get_converted_mat? And would you mind to share your code with us if the reference code no help.

I too am having the same problem. However, my deepstream version is 4.0.1. Can you tell me what exactly should I look for in dsexample? I am using it to save the detections and it works properly on local videos and even rtsp streams to an extent. And randomly PosixMemMap:71 [12] mmap failed comes …

Hi sharanssundar, Please open a new topic for your issue. Thanks

While deepstream-test5 is running, the memory leak can be observed by using the pmap command. After some time (some minutes, up to one hour, depending on free memory) the application fails with the messages ‘Warning - Can’t Map NvBufSurface.’ and 'Warning - Can’t sync NvBufSurface for CPU the patch…

Hey, I have exactly the same problem. I was also able to reproduce the memory leak in test app 5 with the patch posted by by dvir. Is there any solution from NVIDIA? Thanks

I am having exactly the same problem. Are there any workarounds? Thanks

Hi infol7p51, Please help to open a new topic for your issue. Thanks

Hi, I am facing the same memory leakage problem. I wrote a c++ plugin to rotate a frame by a particular angle. For that purpose I used: NvBufSurfaceMap(&ip_surf, 0, 0, NVBUF_MAP_READ_WRITE) to map the buffer and NvBufSurfaceUnMap(&ip_surf, 0, 0) to release memory again where NvBufSurface ip_su…
