Nvbuf_utils: NvReleaseFd Failed… Exiting…

AK51 · April 2, 2022, 2:03am

Hi,

I am running dusty nv code with a rtsp 1920x1080 camera with latency = 0 , there are warning but it does not affect the speed. Is there any setting in camera so there I can eliminate them?
I have been searching in the forum of how to eliminate this warning, but it seems like there is no way of eliminating them, is it? Thx. 'Coz I can not see my own print statement with tones of this warning scrolling down… :<

Hi,
Do you observe the prints if you change the source to video file? Would like to know if it happens in video file playback. And please share which release version you are using.

Hi,
Oh, the mp4 also has the same warning. So, it may not relate to rtsp. Sorry.
For my code, I crop several areas (cuda_mem) of the screen for posenet
poses=net.Process(cuda_mem, overlay=none)
Or, shall I make several cuda_mem instead of using the same one in the for loop?
I wonder if
jetson.utils.cudaDeviceSynchronize()
can remove these warning… Wait

AK51 · April 3, 2022, 9:36am

I’ve just tried to put this in my code

jetson.utils.cudaDeviceSynchronize()
jetson.utils.cudaCrop(img,cuda_mem, crop_roi)
...
jetson.utils.cudaDeviceSynchronize()
poses=net.Process(cuda_mem, overlay=none)

But the warnings are still there…
Pls PM me if you need future info. from my code. Thx

Hi,

I have put jetson.utils.cudaDeviceSynchronize()
everywhere before I call any function related to the jetson.utils… including drawlines and box…
The warnings are still there…

Thx

If I run the same code using c270 webcam (1280x720),I don’t see the warning.
So, it is the problem with 1920x1080? Thx

I have tried to bypass the posenet, there is still some warning but less. I use these functions
Note: I have tried to add “jetson.utils.cudaDeviceSynchronize()” before each call, same warning
And I am using NX already.

jetson.utils.cudaToNumpy
jetson.utils.cudaMemcpy(...)
jetson.utils.cudaToNumpy(...)

Here is the output

If I add just one posenet checking in each frame (print “posenet” before), here is the output

Hi

Herre is the shorten code to demonstrate the warning.
jetson.utils.cudaDeviceSynchronize() cannot eliminate the warning…
Pls use 1920x1080 mp4 for testing. If I use c270 (1280x720) I don’t see this warning

Hi @AK51, that’s because the V4L2 device isn’t appearing to use NVMM memory, and the NVMM library prints these warnings spuriously sometimes when NVMM memory is used - I have not found a way to suppress them, sorry about that.

MIPI CSI camera and compressed V4L2 will use NVMM memory, unless cmake -DENABLE_NVMM=off option is specified. Although these warnings don’t always appear when NVMM is used either, just sometimes. I’ve been unable to find a way to get rid of them (they come from inside a lower-level library, presumably via a printf)

You could use -DENABLE_NVMM=off if you really want to get rid of the warnings, however you would then lose potential performance improvement from using NVMM memory (zero copy)
