• Hardware Platform (Jetson / GPU) Jetson
• DeepStream Version 6.0.1
**• JetPack Version (valid for Jetson only)**4.6.
• TensorRT Version
• Issue Type( questions, new requirements, bugs) Failed to create ‘sink_sub_bin_encoder1’

• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
Running the sample app :
sudo deepstream-app -c source2_1080p_dec_infer-resnet_demux_int8.txt

Hello, i have installed jetpack 4.6.4 on a jetson nano using the sdk manager, then installed deepstream 6.0.1, i’m having issues with the encoder plugin :

sudo deepstream-app -c source2_1080p_dec_infer-resnet_demux_int8.txt 
** ERROR: <create_encode_file_bin:372>: Failed to create 'sink_sub_bin_encoder1'
** ERROR: <create_encode_file_bin:467>: create_encode_file_bin failed
** ERROR: <create_sink_bin:781>: create_sink_bin failed
** ERROR: <create_processing_instance:815>: create_processing_instance failed
** ERROR: <create_pipeline:1326>: create_pipeline failed
** ERROR: <main:688>: Failed to create pipeline
Quitting
App run failed

And when i try to run :

/opt/nvidia/deepstream/deepstream-6.0/samples/configs/deepstream-app$ gst-launch-1.0 videotestsrc ! nvvidconv ! nvv4l2h264enc ! filesink location=out1.h264
WARNING: erroneous pipeline: no element "nvv4l2h264enc"

Although vv4l2h264enc is a component of the library libgstnvvideo4linux2.so and it exists :

/usr/lib/aarch64-linux-gnu/gstreamer-1.0$ ls | grep ibgstnvvideo4linux2.so
libgstnvvideo4linux2.so

I also tried to clear the gstreamer cache and i’m still facing the same error, any help will be appreciated !

Could you try to set the codec=2 and see if it works?

I have changed the codec and i’m getting the same error:

source2_1080p_dec_infer-resnet_demux_int8.txt (4.4 KB)

Even by trying to change the encoder to software encoding, i get a different error:

If you want to use software encoding, you need to install the x264enc plugin.

Could you run the command gst-inspect-1.0 nvv4l2h264enc?

I have managed to fix the issue by reinstalling the NVIDIA BSP packages :

sudo apt install --reinstall nvidia-l4t-gstreamer
sudo apt install --reinstall nvidia-l4t-multimedia
sudo apt install --reinstall nvidia-l4t-core
