I am trying to take photos while the camera is connected to the computer. As soon as the camera is connected to to PC the camera changes it's mode to busy. I would like trigger the camera to take picture while it is connected to the computer.
You can use the EdsSendStatusCommand function with kEdsCameraStatusCommand _UIUnLock to use the camera manually while plugged in. Note that some commands issued with the Canon SDK may lock the camera UI again.

In the agora, there are methods that detect when users turn off the audio (onRemoteAudioStateChanged) of video (onRemoteVideoStateChanged) streams while you are both on a call.
But when one user starts previewing and turns off the cam or mic and then joins a call is there any possibility to detect that on onUserJoined?
I have bought new 2K Full HD webcam. Whenever I connect it to my windows laptop, it gives me green and black lines and it flickers badly.
I switched it to 50Hz and 60Hz in camera APP in windows but nothing worked. Here's the video of the flicker on windows 10: Google Drive Link
But this camera is 100% working fine with skype APP and I have tested it with my friend's MacBook Pro. The camera gives the crispy HD results. But whenever I connect it with windows. It gives me flickering and glitching. Here's the video recorded on skype video setting: Google Drive Link
Both of these videos are recorded in a room and the light in the room is not a bulb light. Its the natural light from the opened window. I have also tested it with bulb light and energy saver bulb, but still the camera is not fixed.
I have updated all of the system drivers, graphics card drivers, change camera app settings and followed every single tutorial to make it work. I cannot buy new one because it's the expensive camera and I can't afford to get a new one. It is working on Mac, Skype but not working on Zoom, Camera APP.
Please do reply to this thread if you know the solution. Thank you in Advance!
I bought this new camera for recording. It is flickering alot. I wanted it to work on windows as it is working on MAC. Thank you!
A. I have a general understanding question about the "still pin" or "snapshot" functionality on some web cameras: how does this work ? It must be one of the following possibilities:
The camera is on and video is streaming to the host. When the snap button is pressed, a signal is sent to the host's camera driver (/dev/input/event0 on linux), the driver extracts a frame from the stream, and sends it up in the stack.
The camera is on and video is streaming (or not) to the host. When the snap button is pressed, the on board firmware puts aside the current frame, and tells the host a new "still" is available.
B. I have 4 usb cameras attached on a R-Pi (single usb host). All cameras have a still pin. I don't care about the video, no need for streaming, I want to take 4 simultaneous photos. My idea is to trigger all 4 cams to capture a frame using the still pin. How can I capture those 4 images without streaming video (bandwidth issues) ?
Note: I have already experimented a lot and I am capable of capturing a frame from a video stream. My cameras are unknown brands but exposes "video capture" as device caps. When using AMCap on windows, the snap button triggers a snapshot.
Thanks for any help.
Could I send an image or video from Arduino IDE to Touch Designer software?
Could I use the pictures saved with the CMOS camera for example?
Thanks,
Giuseppe
You can send images via bluetooth, wifi or serial, but the speed of taking the picture and sending over wont be that fast.
You are better of with a gopro connected via wifi or Canon via usb cable. Forget Arduino if you need a live feed.
I'm working with a Sony DSC-QX100 camera via Sony's Remote Camera api, specifically for use on a Windows 8 tablet (basically replacing the built-in camera of the tablet with this unit). I'm able to consume the camera's LiveView (streaming) and LiveShot (take a picture and retrieve the image from url) features triggered from my application.
My question is whether or not the Remote Camera api exposes any functionality to access pictures stored on the camera's SD card (when it is available). Bottom line, my user may choose to take the picture directly with the camera unit (manually, instead of remotely via my application on the tablet) and I've not yet found the method by which to retrieve this picture from the camera (other than transferring the SD card from camera to pc). Anyone tried this or seen something in the API documentation that I'm missing?
Current Camera Remote API does not provide direct access to SD card.
All available APIs are documented.
