NvMMLiteNVMEDInvbufsurface: mapping of memory type (-1734435427) not supported nvbufsurface: error in mapping Seg fault

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) Xavier
• DeepStream Version 6.0

I just need to understand what causes this error and what it means really. If you need more info, please let me know.

Can you describe in which case/command you found this error? Thanks.

I have a three detector pipeline that gets images through appsrc. A PTZ camera is connected locally and im using camera API to fetch and feed the image through appsrc

then when I try to run the pipeline, this error comes up

Could you attach your pipeline graph and set GST_DEBUG=3 to get a whole log? You can refer the link below:

the pipeline is


did not get any other log with gst_debug

It seems like something wrong with your system. Could you provide more info?
• Hardware Platform (Jetson / GPU) Xavier
• DeepStream Version 6.0
• JetPack Version (valid for Jetson only)
• TensorRT Version
Could you try to narrow down the problem by reducing the number of plug-ins, like:
First: filesrc->jpegparse->nvv4l2decoder->fakesink
Then: filesrc->jpegparser->nvv4l2decoder->nvstreammux->fakesink, thanks

Hey, thanks for quick response, We figured out that it was a camera issue.
