Hi,I run export LD_PRE_LOAD = ./libmyplugins.so deepstream-app -c deepstream_app_config_yoloV5.txt then i got this in my terminal：

any ideas？ thanks

export LD_PRELOAD=./libmyplugins.so instead of export LD_PRE_LOAD = ./libmyplugins.so

export LD_PRELOAD=./libmyplugins.so instead of export LD_PRE_LOAD = ./libmyplugins.so

thanks a lot, but then I got the following error: ERROR: : Failed to create element 'src_bin_muxer' ERROR: : create_multi_source_bin failed ERROR: : create_pipeline failed ERROR: : Failed to create pipeline Quitting App run failed

export LD_PRELOAD=./libmyplugins.so instead of export LD_PRE_LOAD = ./libmyplugins.so

@luvwinnie does it matter where libmyplugins.so is located? I have it in ~/Repo/tensorrtx/yolov5/build/libmyplugins.so
