Device info: v4l2-ctl -d0 --list-formats-ext ioctl: VIDIOC_ENUM_FMT Type: Video Capture [0]: 'YUYV' (YUYV 4:2:2) Size: Discrete 384x288 Interval: Discrete 0.020s (50.000 fps) Gstreamer command: gst-launch-1.0 v4l2src device="/dev/video0" ! …

Hello @dennis.zhang97 , Thanks for providing the output. It seems like the pipeline is not being to negotiate the CAPS between v4l2src and the t element. However, it might be cause because a compatibility issue between the caps of the 2 v4l2sink elements and the v4l2src itself. Would it be possib…

Hello @dennis.zhang97 , Can you run the pipe with GST_DEBUG=3,GST_CAPS:5 ? This might give us a bit more info. regards, Andrew Embedded Software Engineer at ProventusNova https://proventusnova.com/embedded-software-engineering-support/

[image] proventusnova: GST_DEBUG=3,GST_CAPS:5 Sure, here is log file gstreamer.log (75.6 KB)

All three commands executes successfully, I haven’t check the output result, but it should be fine, thank you very much! FYI, video8&9 are virtual devices created by v4l2loopback

Hi @proventusnova , One more thing to bother you, I have another gstreamer command works on Nano but not on Orin Nano also gst-launch-1.0 nvarguscamerasrc sensor-id="0" ! 'video/x-raw(memory:NVMM), width=1280, height=720, format=NV12, framerate=30/1' ! nvvidconv flip-method=0 ! 'video/x-raw, …

It looks like it’s CAPS compatibility issue again but I did videoconvert this time

Hello @dennis.zhang97 , Great to hear that worked for you! The problem with the last pipeline you share I believe has to do with the fact that you are trying to use nvarguscamerasrc to capture from /dev/video0, which according to your v4l2-ctl --list-formats-ext only provides YUYV which is an unsup…

Hi @proventusnova , Sorry I forgot to mention that I replaced another camera, here’s its formats v4l2-ctl -d0 --list-formats-ext ioctl: VIDIOC_ENUM_FMT Type: Video Capture [0]: 'RG10' (10-bit Bayer RGRG/GBGB) Size: Discrete 3280x2464 Interval…

And for that YUYV device, would you mind teaching me how to do munipulation like following python code using gstreamer? It would be really helping. ret, frame = cap.read() if ret: smallBits, bigBits = cv2.split(frame) image_16bits = cv2.scaleAdd( np.uint16(bigBits), np.uint16(256), …

Hi @dennis.zhang97 , Sounds good. What is your end goal? What do you want to achieve with your NVIDIA Jetson system, just out of curiosity? Also, do you have any other questions? Anything else we can help you with ? regards, Andrew Embedded Software Engineer at ProventusNova https://proventusn…
