The deepstream-nvdsanalytics-test frame dropped problem is very serious

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

Everytime I try deepstream-nvdsanalytics-test, the frames went smoothly at the first few seconds, but after that, the log printed: “Warning from element nvvideo-renderer: A lot of buffers are being dropped.”, the frame seems to be frozen, and the program didn’t quit. My input source is rtsp camera source, the resolution is 1920 x 1080.

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU): Jetson Agx Xavier @ 30W 6CORE mode (activate jetson_clocks already)
• DeepStream Version: 5.0
• JetPack Version (valid for Jetson only): 4.4 DP

Hi,
Please add sync=0 to sink and check if it runs more smoothly.

g_object_set (G_OBJECT(sink), "sync", FALSE, NULL);

Thank you DaneL, you save my day, it’s running smooth now! So do you consider modify the app in the following release? I noticed that there’re more than 3 posts mentioned this issue.

Hi,
The sample is for Jetson platforms and desktop GPUs. Certain customization may be applied to it based on the platform. Beside setting sync=false, you may try to configure interval in nvdsanalytics_pgie_config.txt
