Error getting capabilities for device '/dev/nvhost-msenc': It isn't a v4l2 driver. Check if it is a v4l1 driver

[nav007verma]

• Hardware Platform (Jetson / GPU) – GPU (RTX 1080)
• DeepStream Version – 6.1.0
• NVIDIA GPU Driver Version (valid for GPU only) – 510.47.03

I’m getting the below-mentioned error:-
v4l2 v4l2_calls.c:94:gst_v4l2_get_capabilities:<sink_sub_bin_encoderprocessor2> error: Error getting capabilities for device ‘/dev/nvhost-msenc’: It isn’t a v4l2 driver. Check if it is a v4l1 driver.

Output of gst-inspect-1.0 nvvideo4linux2 is

I have removed the GStreamer cache but still, the problem persists.
What could be the issue here?

There is a similar topic report before, can you check if the solution works for your case? Thanks.

Error getting capabilities for device '/dev/nvhost-msenc'

• Hardware Platform (Jetson / GPU) GPU • DeepStream Version 5.0 • TensorRT Version 7.1 • NVIDIA GPU Driver Version (valid for GPU only) 440.95.01 Since the latest driver update, it seems a video decoder device used by DeepStream’s encoder is no longer available. Is there and updated package or a workaround for this? Err msg when trying to use nvv4l2h264enc is: Error getting capabilities for device '/dev/nvhost-msenc': It isn't a v4l2 driver.

@yingliu Thanks for your reply. I’ve already tried the solution mentioned in the above post. nvvideo4linux2 is not blacklisted. You can see the output of gst-inspect in my question.

Are you running in docker container? Can you check your environment with the compatibility table? Quickstart Guide — DeepStream 6.1.1 Release documentation

[nav007verma]

@Fiona.Chen No, I’m not using the docker container. All the Deepstream 6.1.1 dependency has been resolved.

What application are you runing? If it is deepstream-app, can you provide your configurations and command?

[nav007verma]

@Fiona.Chen

I have developed an application using deepstream plugins. I am attaching xdot file
pipe.dot (81.3 KB)

[Fiona.Chen]

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one.
Thanks

From the dot graph you provide, v4l driver is not used by DeepStream. Please check you r application by yourself.

I notice you used GstInterPipeSrc: GstInterpipe 1.0 Reference Manual, it is neither a gstreamer public plugin, nor a DeepStream plugin . Please check which part in your code trigger the nvv4l2decoder by yourself. What we can say is that the NVMM hardware buffer does not support inter-process transferring.
