Hi, I originally repeated this issue using my own live streams. However for ease of anyone to repeat this issue, I have repeated it with the deepstream-app demo. While running the demo with some minor tweaks (details later), the video o/p & performance starts off ok. However, in less than 30 minut…

Hi, Patch in #13 is a quick fix. We have reviewed and updated to new patch set. Please check the attachment. Thanks. DS40X_TEST_0001-gstv4l2dec-Fix-high-CPU-usage-in-drop-frame.zip (1.87 KB)

Hi, Thanks very much for trying to repeat this. I am using the original Jetson Nano Developer kit with a 64GB Class 10 sdcard (no eMMC). I created my sdcard image from your latest updates on 9/24/19…Jetpack 4.2.2 and Deepstream 4.0.1. Did you make the changes that I suggested - especially the …

Hi, this issue maybe the same with me. [url] https://devtalk.nvidia.com/default/topic/1065188/deepstream-sdk/why-nvv4l2decoder-use-too-much-cpu-/post/5395132/#5395132[/url] Thanks.

Hi ClancyLian, Thanks for your update. So I read your post & my take-away from it is that you had normal performance if you don’t set the drop-frame-interval attribute. Since you are using a different SOC to me… “tesla P4 gpu” & we have narrowed down our extremely high use of CPUs to the one vari…

Hi vincent.mcgarry, We will investigate this issue and update to you. Thanks!

hi, Vince , carolyuu Is there a temporary solution to drop frame before decoder ? Thanks.

Hi ClancyLian, Our internal team still investigate issue. Sorry for late responds and inconvenience.

Hi, I have had the same problem for several days. I set “drop-frame-interval” too, and the cpu increase over time. Has this issue been solved?

I also meet the issue in Jetson tx2. once enable drop-frame-interval, the problem will happen in one hour. Jetpack 4.2.2 and deepstream 4.0.1. Can you help me? my project will deploy in December.

Hi, Does anyone from Nvidia have any update on this issue? It has been over a month & it appears from this thread that several others are experiencing the same issue. Thanks, Vince

Hi we can recreated your issue, Our dev team is looking into this issue, sorry for the late response.
