New RICOH R Development Kit Focuses on Live Streaming



Doe’s it mean that all the cables are seen on the video when plugged in on the site :theta_s:
or do the camera also have inlets at the bottom :3theta_s:


I imagine that the internal technology will be able to crop out the cables. I’m not sure though. I have not seen the camera.

I’m surprised that RICOH is releasing the RICOH R Development Kit. Based on this, I’m assuming that the RICOH R Development Kit is not the next-generation THETA S. The RICOH R Development Kit appears to be a potentially low-cost offering for developers that want to use live streaming in their products.

There was also a mention that the RICOH R Development Kit will be available with camera control software that is open source.

The chat session on YouTube indicates that the dev kit will be available in April.


Jumping in here, I’m a little behind. This announcement caught me a little off-guard. In think for developers and businesses looking to build products and services, this could be a really interesting new device.

There are a lot of items that look really great as a developer kit:

  • No battery, uses an AC adapter, can live stream up to 24 hours
  • Real-time stitching on the camera of the two fisheye lens videos
  • Can be controlled with video settings via USB
  • The source code for the video control tool will be publicly released

All of these items (I’m just cherry picking the good ones, there are more) could make this a great platform for building things. Exciting!

Pre-ordering is “coming soon” - Does that mean it’s pre-pre-ordering currently? - so I’ll be keeping my eyes peeled. :3theta_s:


This sounds like a check-list of features that the developer community requested. So awesome! Can you get me a pre-release version for testing? I’ll sign a NDA if I need to.


There’s a 360 degree live stream of CES going on now.

There is a RICOH employee on site that is answering questions about the RICOH R Development Kit in the YouTube live stream chat window.

This is a straight-down view of the live stream from the RICOH R Development Kit

It looks like it is plugged into LiveShell.

The HDMI port outputs an equirectangular video stream and plugs into LiveShell.

This is the view that I’m seeing on YouTube 360 stream now.

THETA USB Live Streaming Now in Full 1080 HD - Free Upgrade

I agree despite the naysayers claiming it was a fail to not release a higher res camera. I think this device is going to really open lots of pro options up.


I’m looking forward to doing more with live streaming. The RICOH THETA S can do a fair amount, actually, but this will be a big step up. It would be fun, for example, to broadcast the RICOH THETA developers meetups in San Francisco, held about every other month. I think this device could handle it easily.


@paulgailey, thanks for joining in the conversation.

I think there’s confusion among people that the RICOH R Development Kit is somehow a next generation of the THETA. It’s not. My understanding from reading the available information is that this is not intended for consumer use. It’s a Dev Kit for engineers or product designers that want to use live streaming in their products for things like surveillance.

I think people want to see the next generation of the THETA S. There’s been no announcement about this yet. I’m sure that when the successor to the THETA is announced, it will be an upgrade in features.

What we have with the RICOH R Dev Kit seems like a stripped down version of the current THETA S with some tweaks.

Remember that back in December of 2015, an enthusiastic member of the community had hacked the THETA S to live stream equirectangular video in Full HD at 29.97 fps using the internal stitching technology of the camera. This is basically the same as the RICOH R Dev Kit. Unfortunately, this hacked camera was never released to the public. Now, it looks like a dev kit of this camera will be available.

This is a machine translation of the specs back in December of 2015 of the community hack.

Full Sphere Live Cam Experimental Machine Specifications:

  • Real-time output of 2K full sphere moving image realized
  • Full HD output from HDMI
  • Equirectangular 1920 x 960 dots 1080 p 29.97 fps
  • In the equirectangular format, horizontal: vertical is 2: 1, so in the full HD the lower 120 dots are black bands
  • Simultaneous monaural audio output from monaural microphone on camera side
  • Turns ON by the connection of the external AC adapter, and video output starts
  • Video control in real time via USB (EV, RGB gain)
  • Continuous operation for more than 24 hours

This is the original Japanese.

全天球ライブカム実験機 仕様:

  • 2K全天球動画のリアルタイム出力を実現
  • HDMIよりFull HD出力
  • Equirectangular 1920 x 960ドット 1080p 29.97fps
  • Equirectangular形式は横:縦が2:1になるためFull HDにおいて下側120ドットは黒帯となる
  • カメラサイドにあるモノラルマイクよりモノラル音声同時出力
  • 外部ACアダプター接続によりONとなり映像出力が開始される
  • USB経由にてリアルタイムに映像コントロールが可能(EV, RGBゲイン)
  • 24時間以上の連続動作

This was the original hack back in Dec of 2015

I think it’s a bit unfortunate that the public is confusing the technology dev kit that engineers can use to build things like VR prototypes or computer vision with the next generation camera.

It seems that the media also had a misunderstanding of the purpose of the DevKit, which is likely the source of the confusion. The release of the information at CES instead of an engineering conference may have also contributed to the confusion by the media.


A person on the CES chat indicated that it was going to be available in April.

I’m most excited about the camera because it appears from reading the public description that the camera uses the internal ASIC to do the live streaming. The ASIC is used for the still pictures which have great stitching. The main problem with using the ASIC is probably heat, which is probably why RICOH took out the battery and added the low-profile heatsink lines.

Back in Dec of 2015, the Japanese article indicated that the heatsink used in the hack was made out of plastic, not metal due to cost. I wonder if they have some metal powder in the plastic of the RICOH R Dev Kit to allow it to conduct meat more easily.


But i think you still need a LiveShel 449 $ to get it going from HDMI

it would be great if it worked directly from USB in or on type: Google hangouts


I believe the output of the USB is also in equirectangular.


There’s a lot of interest in the RICOH R Development Kit. Today, someone was asking about the putting two cameras into a single computer and streaming two equirectangular videos into the same computer. I believe the person’s research is related to low-cost autonomous vehicle navigation and object recognition.

With the THETA S, we can connect two cameras to a single computer with USB and see two dual-fisheye streams. From two cameras, there will be four spheres. Alternately, we can get one equirectangular stream using THETA UVC FullHD Blender and one dual-fisheye stream using the THETA S driver.

As the stitching of the spheres is done inside the camera, it’s likely (though untested) that we’ll be able to get two equirectangular streams into one computer and then do image processing on the two streams.

In addition to two cameras into one computer, there are a large number of other applications that the RICOH R Development Kit might be useful in:

  • stream 24/7 for surveillance with some control of the camera over USB (to be determined what functionality can be controlled over USB). I’m hoping the camera can be turned on with USB like a normal webcam
  • using Linux and thus cheap devices like the Raspberry Pi for streaming. We don’t need the UVC Blender driver, so the ability to stream moves to other platforms, including Android and iOS
  • using a cheap device like a Raspberry Pi (connect to RICOH R Dev Kit) with USB to act as a server using WiFi, allowing 2K live streaming over WiFi
  • connecting an Android or DayDream device (as well as a headset) to the RICOH R Dev Kit with USB and get the equirectangular stream directly into the headset

We’re still in the pioneering stages of live streaming 360 video. Up until the RICOH R announcement, most people have been thinking of streaming as YouTube live streaming. This is primarily because people can’t find a good way to navigate the 360 video stream on a local device without a web browser. with the RICOH R, it will become much easier to stream the 360 video. If we collect information on how to view and navigate the 360 video stream on different devices, it will open up a wide range of applications.


Sirs, any forecast for sale of the RICOH R Development Kit?


During a live chat session at CES, a person mentioned April 2017. So, hopefully in a few months. This date is not confirmed with RICOH. I just heard it from someone at CES.


Master, do you know the function of the two cables?


One cable is power. One cable is video output. The camera can output from both HDMI and from USB. I think that the power input is on a separate cable.


I am searching cable USB extender for 10, 20 or more meters. I will test cable with amplifier, but at first the problem is the USB output of the computer that does not provide 1.5A. I believe that the USB output from the Mac provides a maximum of 1A. I’m going to try a 10-meter cable and see if there is data loss.


Now I understand why the update uses a separate power input from the USB data output. The problem is that we can not wait for the release of this new model. We have to make Ricoh Theta S work with a cable long enough for the MacBook Pro to stay behind the scenes. So the idea of ​​testing a USB extender cable.


Try a powered USB hub. My anker usb hub has an wall outlet adapter for it. I plug the hub into a wall to power the hub and then plug the cables into the hub. Plug one cable from your Mac into the powered hub and another from your THETA into the powered hub. The powered up will bridge the connection. See if you can borrow one to test it.
