I’m running the same version of Jetpack
I can test it with a Z1 later today.
Is the firmware of your Z1 updated? You can use the free desktop app on Mac/Windows of the free mobile app on Android/iOS to update the Z1 firmware.

thanks @Craig we bought 3 Ricoh theta z1 after seeing your post and videos, we thought this could help us in our case but now we’re facing issues but I knew it will be fixed by your support.
cat /etc/nv_tegra_release
Do you know how to upgrade the firmware inside the RICOH THETA Z1?
If you connect the Z1 to a computer with Wifi when the Z1 is a hotspot, you can get the firmware version with:
Yes, I will do this @Craig thanks
I want to use gstthetauvc with opencv for live streaming so please guide me for this.
Is the camera mounted as a filesystem?
@Vijay_Saw unfortunately, there is something wrong with my Jetson Nano and I don’t have equipment to test this with right now. However, I did install and run Jetpack 7.1 (nv_tegra_release) in June of 2023 and it worked fine.
I remember that someone else at a University was having the same problem as you. I believe that the source of the problem was that the camera was being mounted as a filesystem.
Also, I’ve never used Docker with my install. I used Etcher with the image.
Did you get the SD Card Image from this link?
I also used Etcher to flash the image and today I reinstalled everything but still I am getting an error
the only think I have to do is to update firmware
./gst_loopback
start, hit any key to stop
Opening in BLOCKING MODE
NvMMLiteOpen : Block : BlockType = 261
NVMEDIA: Reading vendor.tegra.display-size : status: 6

stop
Isn’t that a different error than you had before?
The original error you posted was Found 1 Theta(s), but none available.
The error you just posted is
Error: Internal data stream error.
Do you have the viewer working with ./gst_viewer
?
BTW, I ordered a replacement Jetson Nano for my personal testing, but it may take 2 weeks to getto my office. In the meantime, we have several years of people testing the Z1 with Linux for streaming. There’s a lot of great information on this site.
yes get_viewer is working and I was getting above error that I have posted earlier on running this command gst-launch-1.0 thetauvcsrc mode=4K ! queue ! h264parse ! decodebin ! queue ! autovideosink sync=false
In the thread above, the person had almost the same problem as you. He marked the last post as “Solution”. Maybe you can try and contact him?
It seemed like the last pipeline worked for him.
Note that in that discussion, the THETA was mounted on the Jetson as a filesystem at some point which caused a problem.
You have the camera showing and working with gst_viewer, right?
$ ./gst_viewer -l

Hello @craig
I am using opencv and thetauvcsrc to get the live streaming on Jetson Nano
VideoCapture cap("thetauvcsrc ! decodebin ! autovideoconvert ! video/x-raw,format=BGRx ! queue ! videoconvert ! video/x-raw,format=BGR ! queue ! appsink");
this is working as expected but FPS is very-very low but I just wanted to know,
Regards,
Vijay Saw
You can use the USB API to:
Alternately, you can use the USB API to switch the camera to video or image mode, which will step the stream over the USB cable.
FPS should be in the 30fps range with a 4GB model of the Jetson Nano without opencv processing. It will drop if you’re using object detection.
I tried all of those command that you have mentioned but it is giving an error device is busy and this is only happening when I am trying to stream more than 15-20 minutes.
Running on Jetson Nano with libgphoto2
or, if you’re using libptp2
The Z1 provides an error with /osc/state
Do you have an error occurring when you can’t put the camera to sleep?

it’ is only happening when I try to close this streaming after 20 min.
even on trying with libgphoto2 getting same error please see
gphoto2 --set-config=/main/other/d80e=1
*** Error ***
The property 'PTP Property 0xd80e' / 0xd80e was not set (0x2019: PTP Device Busy).
seems like Gstreamer pipeline is not closing ?
I can replicate this problem if the camera is streaming and being used by libuvc.
ptpcam --set-property=0x5013 --val=0x0001
Camera: RICOH THETA Z1
'Still Capture Mode' is set to: 0x8005 (-32763)
Changing property value to 0x0001 [(null)] FAILED!!!
PTP: Device Busy
I can switch between live streaming and image when the camera is not being used by libuvc.
Can you try open an issue on GitHub?
@Vijay_Saw , I submitted a community inquiry to ricoh to clarify the USB API specification and I received a response.
During live streaming in “live streaming mode”, MTP commands for changing settings are not accepted.
During not live streaming in “live streaming mode”, MTP commands for changing settings are accepted.
How critical is this feature to your deployment?
