deepstream4.0 GST_ELEMENT_FACTORY gstelementfactory.c:456:gst_element_factory_make: no such element factory "nvstreammux",Why?

I try to install deepstream4.0 and test the sample.

my command like this:

deepstream-app -c samples/configs/deepstream-app/source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt

but I get error:

** ERROR: <create_multi_source_bin:653>: Failed to create element 'src_bin_muxer'
** ERROR: <create_multi_source_bin:715>: create_multi_source_bin failed
** ERROR: <create_pipeline:967>: create_pipeline failed
** ERROR: <main:632>: Failed to create pipeline
Quitting

so ,I use GST_DEBUG=3 deepstream-app -c samples/configs/deepstream-app/source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt and got this:

0:00:00.016348189  4765 0x5574dfe86010 WARN     GST_ELEMENT_FACTORY gstelementfactory.c:456:gst_element_factory_make: no such element factory "nvstreammux"!
** ERROR: <create_multi_source_bin:653>: Failed to create element 'src_bin_muxer'
** ERROR: <create_multi_source_bin:715>: create_multi_source_bin failed

I try to delete the cache file.and get this :

I got many alert info and 14 files in blacklist.but i can’t get nvstreammux.

and I notic alert info like this:

(gst-plugin-scanner:4773): GStreamer-WARNING **: 18:49:55.712: Failed to load plugin ‘/usr/lib/x86_64-linux-gnu/gstreamer-1.0/deepstream/libnvdsgst_dewarper.so’: libcudart.so.10.1: cannot open shared object file: No such file or directory

but ,I have the file use this command:

$ls /usr/lib/x86_64-linux-gnu/gstreamer-1.0/deepstream/libnvdsgst_multistreamtiler.so

/usr/lib/x86_64-linux-gnu/gstreamer-1.0/deepstream/libnvdsgst_multistreamtiler.so

so,the file is ok,but why i can’t open with sudo?

gst-inspect-1.0 nvstreammux
没有那样的组件或插件‘nvstreammux’

my system is ubuntu 18.04 ,with cuda 10.0 and trt 5.1.5.0

so,why i got error?could u help me?

Hi tms2003,

Please check if your NVIDIA driver is the latest one, you could find relevant driver information from official website.
Be sure to reboot the system after installed.

Thanks

I still confuse about which CUDA_VER should I use. I think 10.0, but at nvidia-smi says: 10.1.
All program I compile with CUDA_VER=10.0.

Thank you very much.

Warmest regards,
Suryadi
