Does DS Run Model on Every RTSP Frame?

Hello! I’m wondering if DS 4.0 or 5.0 runs a model (such as the example NVIDIA SSD model) on every single frame or if it would be skipping frames? The frames are handled over RTSP.

The logs I’m seeing look like DS runs the model on every frame but I’m not sure if this could be because frames are actually being dropped and DS is just sequentially numbering the frames that do get processed into the pipeline? Basically asking for clarification on how frames are handled over RTSP. Thanks!

Hi,
You can configure interval to decide the period of processing frames. Please check instruction in development guide.

For running eight sources on Jetson Nano, we have the sample config file:

deepstream-5.0\samples\configs\deepstream-app\source8_1080p_dec_infer-resnet_tracker_tiled_display_fp16_nano.txt

In the config file, interval=4 is set to [primary-gie]. For your reference.
