Memory Leak
Hello @dusty-nv, Can you please help me with the reason for the following warning?
nvbuf_utils: dmabuf_fd 1269 mapped entry NOT found nvbuf_utils: NvReleaseFd Failed... Exiting... [gstreamer] gstreamer mysink taglist, video-codec=(string)"H.264\ (Constrained\ Baseline\ Profile)", minimum-bitrate=(uint)19420, maximum-bitrate=(uint)4039001, bitrate=(uint)332830; nvbuf_utils: dmabuf_fd 1271 mapped entry NOT found nvbuf_utils: NvReleaseFd Failed... Exiting... 1 objects detected detected obj 0 class #0 (person) confidence=0.664551 bounding box 0 (37.000000, 286.625000) (479.000000, 359.000000) w=442.000000 h=72.375000
detectnet is running okay and getting detections too but with the above warning. Any leads would be really helpful.
Thanks
You can ignore that, it is some internal warning from the NVMM zero-copy memory library. Unfortunately I'm unable to suppress the warning because it gets printed by that nvmm library itself.
Hi,
I also see lots of this warning. If I use webcam 1280x720, I don't see it, but if I use IP cam H.264 with 1920x1080/20 fps --input-rtsp-latency=0, it pops up a lots... Even on my NX... Will it be the h.264 is too slow and timing unpredictable? But my traffic is low on my 1G switch. I can tune the input camera stream if required (like fps, constant bit rate...) My application is time critical, is there any way, I can bypass this warning? This warning is annoying that I cannot see my own print statement.... :< I am looking at this forum, https://forums.developer.nvidia.com/t/jetson-utils-videosource-capture-latency-issue/188593/16 Does it mean if I update this https://github.com/dusty-nv/jetson-utils/commit/b38357bbe33640613acb7616fd7e675adbeaab2a I can eliminate the warning?
Thx
Maybe the resolution is the key here. I fixed the warning by changing 1280 x 720 to 1280x768. If there is any downstream task after streaming, maybe there is a code that is accessing a pointer with a garbage value.
