Amelia Viewer by Jake Kenin

This is a fork of Jake Kenin's code to display LiveView video from the RICOH THETA V.
See Jake's original README.

Binaries are available for Windows and Linux in the releases section.

I've added Electron Forge to be able to build binaries for different platforms.

There is an active discussion on this forum here.

RICOH THETA MotionJPEG Streaming

This is a low-framerate, low-latency method of streaming video over wifi.

Live View Specifications (Only still image capture mode) (RICOH THETA S or above) Equirectangular data in MotionJPEG format is output.

Image size: 640x320, 1024x512*, 1920x960*

• RICOH THETA V or later

This project uses the camera.getLivePreview API for the RICOH THETA V. It should work with most RICOH THETA cameras. The API is here reference is here:

https://api.ricoh/docs/theta-web-api-v2.1/commands/camera.get_live_preview/

The Amelia Viewer code references this code for MotionJPEG readable stream.

You can see the working code with the THETA V here:

Wi-Fi Connection Options

You can connect to the THETA in access point mode or client mode. If your THETA connects to your home or office router, you must use digest authentication.

See this link for RICOH THETA digest mode information.

https://community.theta360.guide/t/tip-developing-theta-client-mode-applications/2450

There are many examples of how to connect and authenticate.
