Using the supplied Android demo from
https://developer.sony.com/downloads/all/sony-camera-remote-api-beta-sdk/
Connected up to the WIFI connection on a Sony QX1. The sample application finds the camera device and is able to connect to it.
The liveview is not displaying correctly. At most, one frame is shown and the code hits an exception in SimpleLiveViewSlicer.java
if (commonHeader[0] != (byte) 0xFF) {
throw new IOException("Unexpected data format. (Start byte)");
}
Shooting a photo does not seem to work. Zooming does work - lens is moving. Camera is working fine when using the PlayMemories app directly, so no hardware issue.
Hoping from advice from Sony on this one - standard hardware and demo application should work.
Can you provide some details of your setup?
What version of Android SDK are you compiling with?
What IDE and OS are you using?
Have you installed the latest firmware? (http://www.sony.co.uk/support/en/product/ILCE-QX1#SoftwareAndDownloads)
Edit:
We tested the sample code using a QX1 lens and the same setup as you and were able to run the sample code just fine.
One thing to check is whether the liveview is ready to transfer images. To confirm whether the camera is ready to transfer liveview images, the client can check “liveviewStatus” status of “getEvent” API (see API specification for details). Perhaps there is some timing issue due to connection speed that is causing the crash.

I am developing using EDSDK.
However, if I press the shutter of the camera (physical button) while receiving live view data(EVF Mode), the picture won't be taken. Is this normal?
My camera model is 200D II.
What I'm trying to do is as follows, and it's very simple.
My software activates the camera through EDSDK and receives live view data.
The person behind the camera takes a picture by pressing the camera shutter, and my software shows the picture on the screen.
The questions are as follows.
How to take pictures using physical camera shutter buttons when receiving live view data(EVF).
HDMI connections are not considered because there are features that need to be controlled directly through EDSDK.
Thank you.
Below is what I added after Johannes Bildstein's answer.
As Johannes Bildstein answered, the following code was inserted to unlock the UI.
But it still hasn't been solved.
if (!MainCamera.IsLiveViewOn) {
MainCamera.StartLiveView();
MainCamera.UILock(false);
}
Error message occurs when I try to unlock UI and get EVF data. (Shutter still doesn't work)
If I unlock UI after receiving EVF data,
When dial is in photo mode: EVF data is coming in, but the shutter still does not work.
When dial is in video mode: EVF data does not come in due to BUSY error. Is it a conflict due to UI unlocking? We check your answers and SDK documents and try in many ways, but they are still unresolved. We are currently testing the more recent model, 200D II.
"| EvfOutputDevice.Camera " should be added like below!
public void StartLiveView()
{
CheckState();
if (!IsLiveViewOn) SetSetting(PropertyID.Evf_OutputDevice, (int)(EvfOutputDevice.PC | EvfOutputDevice.Camera ));
}
The camera "UI" is probably locked. The EDSDK does that automatically when connecting and before doing certain commands. You can unlock it with EdsSendStatusCommand using kEdsCameraStatusCommand_UIUnLock.
I am developing a python remote control application using the open source pysony library. The program should be able to shoot images in a loop, download them and then delete the artifacts on the camera (We can't manually format the sd card, since the idea is that, of a remote control application).
I'd like to point out, that I have read this post about the correct way of remotely deleting files. I have read the Sony API documentation and have successfully managed to control everything I need to, but the deletion of images. The camera in question is a Sony a6300, updated to the latest firmware as is its API.
The problem in question is the fact that the camera returns a success response ({'result': [], 'id': 1}) after trying to delete a set of image URIs, but the images still remain on the camera. I am using the remote control app and am connected directly to the camera wifi (making this the standard 1:1 connection). When I issue the delete command, the screen of the camera shortly displays a "controlling with smartphone... you cannot directly operate this device" message.
I have searched all around the www an can't seem to find and aswer.
Thank you in advance!
I am developing Phonegap Application and my application has scenarios where camera is used very frequently.
In my application I have used custom camera plugin (https://www.npmjs.com/package/cordova-camera-custom) to take picture and use it in my application.
Now when I capture images from this camera 30 times by opening camera and capturing again and again the app goes to crash.
The app just crashes so I am not able to identify the root cause of the crash.
I am not an iOS Programmer though I have tried to check the plugin code but I was not able to find the cause.
You can even check the plugin code on your end if needed.
I have also posted this issue to DevExtreme, the framework which I am using to develop hybrid applications at following link:
https://www.devexpress.com/support/center/Question/Details/T480068
and they found that issue indeed is related to memory shortage. The error message was with bug_type: 298 and fault cause: vm_pageshortage.
Please help me on this, I am struggling on it since long before.
Any Help is greatly appreciated.
I am trying to control my Camera DSC-RX1RM2 with Remote SDK.
With the PDF guide [Sony_CameraRemoteAPIbeta_API-Reference_v2.20.pdf],
I think I can use [Continuous shooting mode]API for my Camera,
But the result always return ["error": [12, "No Such Method"]].
I want to ask where is the problem?my camera or the SDK or my source?
Unfortunately, the DSC-RX1RM2 is not supported by the API. Stay tuned to the Sony Camera Remote API page for any updates on supported cameras - https://developer.sony.com/develop/cameras/.
The latest API does support the DSC-RX1RM2, just confirmed it.
Also check that your URLs are like:
http://ip:port/sony/camera
or
http://ip:port/sony/avContent
I didn't append camera or avContent at first and got similar No Such Method errors.
I have two or more cameras connected to my pc. My goal is, to switch between the local cameras in an ongoing webrtc videoconference - but only to switch video from camera 1 to camera 2 NOT audio. Audio should always come from camera 1.
How to toggle between the two videoTracks?
See this answer.
Basically you can use replaceTrack() in Firefox to do this today for a seamless replacement of a camera. This is being added to the spec, but Chrome doesn't support it yet.
The best you can do in Chrome today is to get a new stream with the same mic but a different camera, remove the old stream/tracks from the PeerConnection and add the new one, and then handle onnegotiationneeded and renegotiate. This will likely cause a glitch, and will require at least a couple of round-trip-times to complete. (This will work in Firefox as well.
