Nvbuf_utils: dmabuf_fd 1106 mapped entry NOT found, nvbuf_utils: NvReleaseFd Failed... Exiting

[user152011]

Hi guys!
I already read some post about this topic, but it doesn’t help me.
I am using the Capture and Render functions from jetson-utils and then I use some OpenCV cuda functions.
I use two 60fps, Full-HD mp4-input videos. For one frame the needed time is round about 16,6 ms for 60 fps.
Here is my problem:
Only for some frames I get the two warnings/messages:
1.
nvbuf_utils: dmabuf_fd 1106 mapped entry NOT found
nvbuf_utils: NvReleaseFd Failed… Exiting…

and
2.
[gstreamer] gstreamer mysink taglist, video-codec=(string)“H.264\ (High\ Profile)”, language-code=(string)en, bitrate=(uint)5992786, minimum-bitrate=(uint)865440, maximum-bitrate=(uint)23660640;

For the first problem: as consequence the running time of the current frame doubles from 16 ms up to 33 ms (see picture).
I would like to know, how to avoid this fact, that one frame do not behaves fine in this pipeline of streaming.
My suggestion is that the one frame is left out and, for the next frame the timer includes the time for the failing frame. So the needed computation time doubles.

The second warning doesn’t seem to have an negativ impact, but I would like to know its meaning and how to avoid it too.

Another question: there another possibility to capture frames of a video directly in the GPU of the jetson boards to use opencv function? My solution was using jetson-inference, but maybe there is still another solution.

Thank you for your advices! I will be glad to read them!

Hi @user152011, this warning seems to occur sometimes sporadically, but if you want to disable NVMM you can compile jetson-inference/jetson-utils with cmake -DENABLE_NVMM=off ../ option. Then re-run make && sudo make install

This isn’t an error or warning, it’s just an informational message from GStreamer about the incoming multimedia stream. If you want to suppress it, you can use --log-level=info or comment out this line of code: https://github.com/dusty-nv/jetson-utils/blob/8b6c5ca4b2b52d51f5415ce033ee52563ddf3f2c/codec/gstUtility.cpp#L348

Thank for your reply!

Concerning the first question: Do I have to expect losses concerning the performance (runtime) of the code if I disable NVMM? Because that is definitely not what I want.

Concerning the second one: the first try of supressing the informational message by adding --log-level=info in the terminal does not work. It gets printed anyways.
For the second advice: after comment out the line. Do I have to recompile and do I have to to that?

Thank you again for your response!

Is this still an issue to support? Any result can be shared? Thanks
