when i use tracker, object id only show in the later part of the video. i can’t get the tracker id at the begining.

Not very clear about your question, Are you using deepstream-app, have you checked https://docs.nvidia.com/metropolis/deepstream/dev-guide/index.html#page/DeepStream%20Development%20Guide%2Fdeepstream_app_config.3.2.html%23 and https://docs.nvidia.com/metropolis/deepstream/plugin-manual/index.html#page/DeepStream_Plugin_Manual%2Fdeepstream_plugin_details.02.02.html

i solve this problem, i recompile the tiny yolo V3.thanks all.

but i have another problem. i try the NvDCF in rtspsrc, the track id not change when detected object disappear. I try IOU and KLT successfully.

NVDCF should work, could you check your config file for NvDCF. BTW, pls create a new topic for the new problem.

it’s the topic

NvDCF work when new object showed, but when object disappear, the object id does’t changge to -1

Let’s close this topic and track the problem on that topic .
