You can use your mobile phone as a hotspot and stream to a RTMP server like Facebook or YouTube with the plug-in below:
http://theta360.guide/plugin-user-guide/wireless-stream/
You can get the 4K stream onto something like Oculus Go with webRTC.
I do not know of any public application that allows a USB cable to stream to an Android device.
I know people have successfully done this for their own work projects (source code not released).
Super great work you are all doing here! I have a project that I am doing right now in Panama where I am trying to make 360 Camera trap prototypes. We got the first up and going with the MADV camera because it was easy to control with two pins they had broken out that you can just short to turn the camera on and take photos, etc

But now i am trying to make one with the Theta V, but running into much more difficulties.
The basics we need are to:
I asked Theta support and they told me it couldn’t be done.
But after some hacking, i have some promising findings.
A) If i connect an arduino via an OTG cable set up as a Human Interface Device (HID), and send it a key stroke, it will wake up from sleep
B) If i run the HID plugin on the Theta V, i can completely control the shooting with an Arduino emulating a keyboard (It’s great!). BUT the camera will not automatically start up in Plugin Mode
C) if i connect the CA-3 remote shutter, it can make the camera take photos without any plugin over the USB, BUT the CA-3 cannot wake the camera up.
So I am able to do all the actions i need, but not all with the same device.
Does anyone know
A) how to send the USB Api triggers from an Arduino? (Teensy has USB serial support)
B) How to start up the camera in plugin mode?
or
C) What the CA-3 is sending to trigger the photo?
Another question will be:
is it possible to supply power TO the Theta over the USB while also sending messages?
I know that it is possible to draw power from the Theta to run my Teensy attached to just the USB for example, but i don’t know if i can send power the other way?
You can power the THETA over USB and send USB API commands to it. It will work indefinitely. I need to review the rest of your questions in more detail. Breakfast is on the table. Have to run.
ptpcam and programs using libptp2-1.2 may not work properly without a small modification to the line 77. Change the PTP_USB_INT_PACKET_LEN to 28
to install in /usr/local/lib and usr/local/bin run
$ make clean
$ make
$ sudo make install
In your ~/.profile, add this line:
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib
run
source ~/.profile
Alternately, you can add the library path to a file in /etc/ld.so.conf.d and run
$ sudo ldconfig
craig@jetson:/etc/ld.so.conf.d$ cat libc.conf
# libc default configuration
/usr/local/lib

Library for operating MTP devices from C# and operating cameras such as the RICOH THETA.
With ptpcam -R, it can send a raw generic PTP request with parameters. The returned result could be reformated to shutter speed settings of Theta S. First read properties available, 0x1014 for reading device property description and 0xd00f for shutter speed. In the returned values, all the possible shutter speed is listed. For example, 01 00 00 00 a0 0f 00 are two 4-bype integers, 01 00 00 00 is 1 and a0 0f 00 00 is actually 0f a0 which is 6400.
$ ptpcam -R 0x1014,0xd00f,0,0,0,r

To get current setting of a property, 0x1015 for get property and 0xd00f for shutter speed:
$ptpcam -R 0x1015,0xd00f,0,0,0,r
Camera: RICOH THETA S
Sending generic request: reqCode=0x1015, params=[0x0000d00f,0x00000000,0x00000000,0x00000000,0x00000000]
01 00 00 00 3c 00 00 00 00 00 00 00 - ....<.......
PTP: response OK
The result 01 00 00 00 3c 00 00 00 could be read as (01)/(3c) = 1/60
To set shutter speed, could send binary data with ptpcam -R. To send 1/8, use 0x1016 for set property:
echo -e -n '\x01\x00\x00\x00\x08\x00\x00\x00' > shutter.bin
ptpcam -R 0x1016,0x00f,0,0,0,0,shuuter.binThere’s a new Linux streaming driver that allows streaming over a USB cable to a Linux computer. I’ve seen it working a NVIDIA Jetson with the livestream controlled by the USB API.

According to the past thread, it seems to work on Ubuntu 14.xx, but I want to use ROS Kinetic, so I can’t change the version down.
I hope you can somehow make it possible to record video.
Also, there are a number of other commands that can’t be executed for something else.
Is this an error for the same reason?
I’ve written a version of the elements that might be necessary for a smooth resolution.
I’ll keep adding to it as requested.

ptpcam -R 0x101c,0,0,1
wow!
Thank you so much, craig!
What an easy, simple, startling, brilliant answer! I can’t believe that adding just “,0,0,1” to the bottom works perfectly!
My less than 4 hours(?) So much trouble and time spent searching can be solved with just one post!
That’s the power of community! That’s fantastic!
I knew from the specs to add “,0,0”.
But where is the information on the last “,1”?
I thought I did my best to look into it, as mentioned above, but I couldn’t find a way to do so.
Maybe I just missed it.
But still, thank you so much.
Hi all, glad to find this community! I’m new to theta development. We are now working on a project to setup a Theta Z1 camera in a remote site. The Z1 camera is connected to a computer through USB and we use it to stream live 360° video. As it’s a remote site without regular workers, we want to control the camera remotely. Sometimes we may put the camera and computer into sleep mode. However, we can’t find a way to turn on the Z1 camera from the sleep mode. We have to turn on the camera by manually pressing the power button. I would like to know if there’s a way to turn on the camera from the computer with USB connected. Thanks a lot!
$ ptpcam --set-property=0xD80E --val=0x00
Camera: RICOH THETA Z1
'UNKNOWN' is set to: 1
Changing property value to 0x00 [(null)] succeeded.
@NaokiSato102, thank you for the nice note. With the surge of interest in the live streaming to Linux topic, there is now more activity on the USB API. I am working on a new document with a table of contents. If you have additional questions, feel free to ask.
My current test setup:
If this information is useful, you can help us out by telling us more about your project. 日本語 is OK.
We report back to RICOH on what the community is doing. This helps us maintain sponsorship for testing and creation of documentation we can make available to the community. You can send the information to @jcasman by DM or email. Thank you.
I added the information to the new document which is available to the people that registered for the meetup right now. We’ll make it available to everyone else in about a week.
Thanks Craig! We will give it a try!
I understand, @craig.
I can just let @jcasman know what I’m doing by DMing or some other way, right?
But what kind of content should I send? I don’t know if I can send just the content to @jcasman because it might confuse him.
Would the following be sufficient?
Greetings
Brief self-introductions
@craig asked me to introduce what I’m doing.
Contents(what I’m doing)
I’m waiting for your reply.
By the way, will the URL be posted here when the document is completed or published?

Is it @craig or @jcasman who says it’s okay to speak Japanese?
This is what it looked like when I tried it in my environment. Is it the same for all of you?
What I can see from this table is that, for now, it’s safe to use “ptpcam -R 0x101c,0,0,1”.
私の環境で試したところこんな感じになりました。みなさんも一緒ですか？
この表からわかることは、とりあえず、「ptpcam -R 0x101c,0,0,1」を使っておけば安泰ということですね。

yes, I believe it’s the same. I believe the V and Z1 are the same.
I must have first encountered this in Sept of 2017 with the V. See this post. There must have been a problem with the V without the additional 0,0,1
Thank you for your help. Please fill out the short survey below. Japanese is OK. Both @jcasman and I can read Japanese.
Is there anyone can give me a complete guide of how to do API over USB Cable for Z1, as I am not a developer so it is kinda hard for me to understand the process. I want to try to do a factory reset to my Z1 using API, maybe it would fix the problems, as my Z1 won’t boot and keep getting error during the boot process.
