Hi, new to the forum sorry if this has been asked before.
We are developing a native Windows 10 Application (C++), and need to control the Theta Z1 camera to:
Take still shots and record videos
Transfer the media to a PC
Delete media from the SD card
Put camera to sleep
The hardware setup is unattended, it must perform those operations without any human interaction (button presses, etc). Can we do that? I saw some web/JSON-based interfaces, which I suppose we could use from under Windows as well. Is there documentation on those APIs/Interfaces? Any sample code would also be greatly appreciate.
If your use case allows the use of sleep and awake, it is better to use sleep and awake as the API is listed on the RICOH site.
We don’t have any sample applications with Windows MTP.
You may be able to use gphoto2 on Windows as well.
There are more examples using Linux with libptp2 because people are often using a Raspberry Pi due to low cost and size.
Are you using the Windows machine to control the camera because you want to show the boat passengers the pictures and you’re using the Windows machine form something else as well? Maybe you already have a Windows machine on the boat?
BTW, I’m just curious, but would you be able to post a picture of the boat? I used to fish a lot with my son when he was younger.
Re:sleep / awake
Sure, that’s a good option. We are fine with sleep/awake.
Does not look like there is a windows version, in any event, this is a commercial setting, I dont think GNU GPL would be acceptable
Re: Why Windows?
Yes, we need the capture to happen on a Windows machine because that’s where the rest of our extensive software stack is, from processing and biz logic, to communication and remote mgmt.
Re: Picture of the boat.
Sure! Once (if) we succeed with integration. Now leaning towards X
Suggest you buy the camera from a place with a return policy. It’s possible that the X may generate more heat than the Z1 with the current firmware. Even if you turn off the LCD screen of the X, it may still be a bit hot. There has not been as much long-term testing with the X, especially inside of an enclosed case.
I did test the USB API of the X and it worked fine in my limited tests.
I believe the Windows MTP extensions work without any issues.
There are 192 clicks on the MTP extension link on our forum and people haven’t reported problems.
This is the tip from MattWymore.
The correct way to do this is to use
WPD_COMMAND_MTP_EXT_EXECUTE_COMMAND_WITHOUT_DATA_PHASE and set up all
the parameters and Op Code for image capture and then send that command. Take a look at this
example from Microsoft for setting things up. Basically you just need to change the Op Code to
0x100E (for initiate capture) and change the StorageID to 0x0 (as documented in the Theta v2
USB API) and you are ready to go.
It’s likely that people are using the MTP commands from Windows and because there are no problems, there is no discussion on the forum about it.
Once you have a few basic commands working, suggest you take the camera out in the sun inside the weatherproof case to simulate the use case of mounting it to the boat. You may need to circulate air inside the case.
It’s possible that X may run cooler if you take out the battery as the power charger for the battery likely generates heat. The X can run without a battery in it.
