Hello, I’m using an usb camera on jetson nano. [https://developer.nvidia.com/embedded/learn/tutorials/first-picture-csi-usb-camera](https://developer.nvidia.com/embedded/learn/tutorials/first-picture-csi-usb-camera) I have refered to above url. Enter the following command to display a core dump. You can check ls /dev/video0. How do I use this camera? ~$ nvgstcapture-1.0 --camsrc=0 --cap-dev-node=0 Encoder null, cannot set bitrate! Encoder Profile = High Runtime USB Camera Commands: Help : ‘h’ Quit : ‘q’ Set Capture Mode: mo: (1): image (2): video Get Capture Mode: gmo Capture: enter ‘j’ OR followed by a timer (e.g., jx5000, capture after 5 seconds) OR followed by multishot count (e.g., j:6, capture 6 images) timer/multihot values are optional, capture defaults to single shot with timer=0s Start Recording : enter ‘1’ Stop Recording : enter ‘0’ Set Preview Resolution: pcr: e.g., pcr:2 (0) : 176x144 (1) : 320x240 (2) : 640x480 (3) : 1280x720 (4) : 1920x1080 NOTE: Preview/Encode resolution will be same as Capture resolution for USB-Camera Get Preview Resolution: gpcr Get Image Capture Resolution: gicr Get Video Capture Resolution: gvcr Set Capture Device Node: cdn: e.g., cdn:0 (0): /dev/video0 (1): /dev/video1 (2): /dev/video2 Get Capture Device Node: gcdn Runtime encoder configuration options: Set Encoding Bit-rate(in bytes): br: e.g., br:4000000 Get Encoding Bit-rate(in bytes): gbr Set Encoding Profile(only for H.264): ep: e.g., ep:1 (0): Baseline (1): Main (2): High Get Encoding Profile(only for H.264): gep Force IDR Frame on video Encoder(only for H.264): Enter ‘f’ \*\* (nvgstcapture-1.0:13071): ERROR \*\*: 18:46:12.602: \ nvvidconv element could not be created for image encode.

Hello, Yes when I try in 4.6.1 In Ubuntu’s Cheez app, the USB camera video is also displayed. nvgstcapture-1.0 --camsrc=0 --cap-dev-node=0 nvgstcapture-1.0 --camsrc=0 --cap-dev-node=1 In this way, I confirmed that the video came out of up to two USB cameras. If more than 3, a message appears indicating that the buffer is insufficient. Any idea why it doesn’t work in 4.4 and not in 4.6.1? Thank you. ---

Current only USB3.0 web cam for above 3 sensor. Sorry don’t know the detail fix for J4.6.1 ---
