Strategy 1 - relay stream to high-powered server for processing

to relay the stream to another server, you can also reference the great project from @Hugues.

Low latency (0.4s) H.264 livestreaming from Theta V WiFi to html5 clients with RTSP plug-in, ffmpeg and Janus Gateway on raspberry Pi

Hello, After many tries on Theta V, I achieved to get a H.264 livestreaming on a Raspberry Pi for multiples html5 clients with a 0.4s latency. It uses almost all realtime protocols available and powerfull softwares just to bypass USB livestreaming witch is not available on linux ! How it works: Theta V with RTSP plug-in connected in client mode (should work in AP mode too, 5GHz WiFi for better bandwith). RTSP with Device WebAPI Plug-in also works. ffmpeg (running on a Raspberry Pi) gets the…

Strategy 2 - Process Inside the RICOH THETA Camera with Plug-in

Projects that use OpenCV or FastCV inside the camera:

Note that FastCV is a free library that uses the Qualcomm Snapdragon hardware acceleration. The RICOH THETA V and Z1 use the Snapdragon hardware and run Android OS inside the camera.

• FastCV Painting
• THETA Magic Filters (with GitHub Repo)
• FastCV on RICOH THETA article

Strategy 3 - Process with small board Linux computer attached to RICOH THETA with USB

The NVIDIA Jetson Xavier has a 512-core Volta GPU with Tensor Cores and an 8-core ARM, 16GB of memory with 4K H.264 hardware encoder/decoder. It may be enough to process some of your computer vision requirements.
