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!

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.
I'm trying to get an image capture from the front or back camera of my smartphone using the WebRTC. I used one of WebRTC samples for that. This code works perfectly in browsers on the computer, but on the smartphone with different operating systems (iOS, Android) I get a black screen in the tag <video autoplay></video>. I tried various browsers, in none of them the image capture function worked properly, everywhere a black screen was displayed. What should I do to capture the picture?
I have a http connection, all my smartphones and cameras work fine, so the problem is definitely in WebRTC (or in its use).
For Safari, try adding playsinline to the video element. See this thread for background information.
If that doesn't help you might want to check the mediastream as well as the video elements readyState property.
I have been using android studio and its AVD for a long time. I have used the webcam as the back camera with no problems.
I had a working app that took a pictures with the phones camera and updated an image view with the returned bitmap thumbnail.
I then decided to try and use files rather than bitmaps to improve the quality of the image by following the following tutorial..
Android tutorial: Taking Photos Simply
I did not manage to get it to work so reverted back to using the bitmap thumbnail.
My problem is, now when I use my mac book webcam to take a picture using the emulator, the image is so under exposed that it is returning just a black square (unless I am pointing it directly at a light source.
Has anyone any idea of what could have happened and how to fix it?
(I do not think this is related to my app as even when creating a new emulator and just running the built in camera app I get the same problem)
I am trying to record a video of my app using QuickTime and the new iOS record feature in Yosemite. Problem is all I get is a black screen. Can anyone assist?
I found the solution. It wasn't able to see video until I switched from my Blue microphone to the iPad's built-in one.
in the QuickTime Player go to > File > New Movie Recording
Click the Arrow (that points down) next to the red Circle
in the Camera choose your iOS device , if it not showing , unplug and plug your iOS device again. if you would like to record the sounds that your iOS makes , change the Microphone as well.
Hope this helps.
I've been struggling to make video on the iPad work. I'm using an MPMoviePlayerViewController and it plays fine in the simulator. I've tried several different converters, including ones dedicated to producing iPad-formatted video, but none of the videos play on the device. The MPMoviePlayerViewController loads and the controls appear.
For most of the videos, the spinning progress indicator never goes away. For a few, the video loads but when I press play the video immediately pauses. I know that the video is there because I can scan through and see various frames.
I know the code works because it plays a different movie file perfectly. I just have no idea what I'm doing wrong that's preventing my movie from playing. Does anyone know a good step-by-step process of getting an iPad-formatted video from any .mov or .mp4?
Thanks,
Luke
Also, just for future reference, import target video into iTunes, then highlight it and from the Advanced menu choose "Create iPod or iPhone Version" or "Create iPad or AppleTV Version" depending on your target device.
This guarantees that the right codecs are used and the right bitflags set on the video file.
Fixed - the one that loaded but couldn't play eventually worked. Why? Who knows.
