Показать описание
RICOH THETA streaming 4K 30fps video to an NVIDIA Jetson Nano using an USB cable. Processed in real-time with OpenCV 4.4 compiled with cuda support. Uses libuvc-theta to get the JetPack 4.4 (Ubuntu 18.04) to detect the THETA.

Hi, theta s can do the same (360° live stream on a jetson/raspi board with usb connection) ?

Hello, i was able to successfully install libuvc theta following your linux streaming guide.
In the gst_viewer.c file i had to keep following settings
v4l2sink device=/dev/video1 sync=false" / line number 187

pipe_proc = "nvv4l2decoder ! nv3dsink sync=false"; / line number 191
After this i am able to view the camera stream on my Nvidia Jetson Xavier as well as Tx2 successfully.
But while running this example with
Device id as 0, I get this error :
select timeout
VIDIOC_DQBUF: Resource temporarily unavailable

Device id as 1, I get
VIDEOIO ERROR: V4L: can't open camera by index 1
camera open failed

I have put camera in live mode

Any suggestions how to solve this issue ?
For Nvidia Jetson TX2, Opencv 4.1.1 with Theta V
