This application is based on yolov5. the FPS drop to 0 when i set “sync=0” in [sink] group, but it works fine if sync=1.

here is my config:
deepstream_app_config_yoloV5.txt (3.2 KB)

anyone reply?

With DS 6.0, nvtracker is changed. Your tracker configuration in deepstream_app_config_yoloV5.txt (3.2 KB) is not correct.

I’ve tried with source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt in /opt/nvidia/deepstream/deepstream-6.0/samples/configs/deepstream-app, with both “sync=0” and “sync=1” for [sink 1] group, the app works well. “sync=0” is much faster than “sync=1”.

Hi, it still happened when i disabled nvtracker. I’ve found that sync is not the main factor,the problem occurs with “enc-type=0” for [sink1] group, but the app you metioned works well with both “enc-type=0” and “enc-type=1”.
Can u give me some reference to locate this problem?
