Tool/software:
Hi expert,
I have adapted the X3C camera. However, when using the Python script to retrieve the stream, an error "[ERROR] Error pulling tensor from GST Pipeline" occurs. Could you please help me figure out the cause? In addition, when using the GStreamer command alone to obtain the video stream, it is successful.
