Nvds_obj_enc_process for whole frame leaves aritfacts over time

I don’t have a A3000 GPU, but I have tried on many other GPUs. Cause I can’t reproduce the issue, so Could you help try to debug this? Try to set the userData.quality to 95. It will affect the quality of jpeg coding. Thanks

Hi yuwiew,

With userData.quality = 95:

With userdata.quality = 100:

@syther666 , I have tried in Ampere architecture GPU, it still have no problem. So I think we can only rely on you and your own environment to debug this problem.
There are two methods I can think to try:
1.just change the source (sample_720.h264…)
2.You can refer the link below to get the data from NvBufSurface directly, and see if it’s the same issue. Then we’ll know whether it is the jpeg coding problem or the plugin processing problem. Thanks

RTSP camera access frame issue

Hi DaneLLL, I tried your suggestion. I also referred the documentation for providing appropriate parameters. I could understand that I need to pass -1 for computation of all buffers. However, I am still unable to get the output for second stream. I get null pointer for “dst_surface->surfaceList[1].mappedAddr.addr[0]” using these parameters. Please find my code below: /** * Buffer probe function after tracker. */ static GstPadProbeReturn tracking_done_buf_prob (GstPad * pad, GstPadProbeInfo *…

There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
