Re: Webcam Camera
Leana Eckes
The webcam has been correctly assigned an ID of 0 because there's only 1 camera. However, mNumberOfCameras is presumably still 0. This means that the camera is being registered by the emulator, but it hasn't bothered to update the number of connected cameras.
Edit 2: This seems to be a bug in the emulator. The suggested answer tells you what to do to set up the camera, but doesn't solve the problem for me. I ultimately solved it by using a laptop with a built-in webcam. Perhaps another USB webcam might have worked as well.
If the Android Camera is still not working after launching it with elevated permissions via the Terminal, in System Settings.app, navigate to Privacy & Security -> Camera and ensure the Camera Permission for Terminal is enabled

Use your phone's camera as a wireless webcam in your PC or Mac.
Install Webcam for Windows, Mac or Linux, download Iriun Webcam app to your mobile phone and start using the phone with your favourite video applications.
With Continuity Camera, you can use your iPhone as your Mac webcam or microphone, and take advantage of the powerful iPhone camera and additional video effects. You can connect wirelessly, or with a USB cable for a wired connection.
Remove your iPhone as an option: On your iPhone, tap Disconnect, then confirm that you would like to disconnect. Your iPhone is removed from the camera and microphone lists in apps, and also from the list of sound input devices in Sound settings.
When you use your iPhone as a Mac webcam, you can use the Video icon in the menu bar to use video conferencing features. For example, Desk View shows a top-down view of your desk, and Studio Light dims the background and illuminates your face.
Get a rare view of the Farallon Islands' craggy peaks and rocky shorelines and scan the islands for marine mammals and birds. Our high-definition webcam is newly restored and now streaming live from a lighthouse atop Southeast Farallon Island.
The islands of the Farallon Islands National Wildlife Refuge are managed by the U.S. Fish and Wildlife Service and are located nearly 30 miles off the coast of San Francisco. The Farallones host globally significant wildlife populations, including hundreds of thousands of seabirds and thousands of seals and sea lions. They are also a place of science where biologists from Point Blue Conservation Science study this complex ecosystem every day of the year, looking at the data to find ways to guide conservation and restoration of the islands in the face of climate change and other threats.
Because of the important and sensitive seabird and mammal populations that use the Farallones as breeding grounds, the islands are not open to the public. They are accessed only by a small number of wildlife biologists and resource managers. Point Blue Conservation Science has been doing science and training the next generation of scientists on the islands since 1968 in partnership with the U.S. Fish and Wildlife Service.
What is the problem? Trying to increase resolution and quality of web cam and OctoLapse videos. I would like the web cam image to be of better quality when I full size the dashboard and would like OctoLapse to render either 720p or 1080p (preferred) video with better image quality.

So setting camera="raspi" allowed me to use the camera_raspi_options value, but I still get the same issue where resolution isn't actually increased, it just zooms in and gets blown up with worse quality.
It looks like my issue is related to this.
Raspberry Pi Camera V2 Settings? Webcams When I edit the camera settings in octopi.txt for my raspi cam, it zooms in like crazy and crops out most of the frame. I removed the hash tag for these two settings. camera="raspi" camera_raspi_options="-x 1920 -y 1080 -fps 30" I am running the latest version of OctoPrint This is my code: [image] This is my defaul setting result [image] This is my 1920x1080 settings result [image]
Sure we can increase resolution easily but the bitrate is not enough to support it. I get bad compression artifacts at 10Mbps? Netflix can stream you nearly 4k HDR UHD with that. Whereas here I can't get a reasonably clean 1640x1232.
I am using a MacBook running macOS 14.4 and using it with a large external monitor. I have a webcam installed on my monitor. For the past month, my screen has been turning itself off during Zoom meetings (going into video hiding mode). Additionally, for the last few days, the webcam camera has been blinking, so I cannot use it.
I'm having the same problem and have tried everything I can to fix it. I've reloaded Zoom several times and tried different external cameras and dongles, all to no effect. Have you or others had any luck?
So I check that when I open Camera Hub and change the frames to 1080p60 or 720p60 it stops the flicker/blinks. But I need to keep opening the Camera Hub app while using Zoom which is annoying but it does the trick
Arriana Vasquez is an updates writer for Wirecutter who also works as a professional product photographer, for which she shoots everything from rings to raincoats. For Wirecutter, she has worked on several camera-related guides, including our guides to instant cameras, instant photo printers, and tripods.
The current version of this guide builds on the work of Wirecutter senior staff writer Melanie Pinola, who has written about technology and home-office topics for more than 12 years for sites such as Lifehacker, PCWorld, Laptop Magazine, and Consumer Reports. She has tested and reviewed various gear for Wirecutter for more than four years.
Once we narrowed down the field, we took multiple pictures and videos with each webcam under controlled conditions so that we could compare them directly. With each contender, we captured the following:
We then asked a panel of Wirecutter staffers to compare the images and videos from the different cameras, without knowing which was which, and to rank their quality from best to worst. We used that data, our findings from the previous version of this guide, and notes from other professional reviewers to arrive at our picks.
Its autofocus works quickly, and its exposure and white balance are very accurate. Even in rooms with a mix of sunlight and warm overhead light, or where we sat in front of a bright window, the Brio 505 delivered a more color-accurate image with snappier autofocus than the higher-resolution Logitech Brio 4K.
Generally speaking, these options all work the same way: After you install software and connect the device (over USB or Wi-Fi in some cases, but USB is more reliable), you can select that device as the camera in web-conferencing and video-streaming apps. You should also have a tripod or some other way to raise the camera or mobile device to the proper height.
Though such features are more than what most people need, Camo is a more affordable alternative to buying a DSLR. The software is simple to use, and we found the video quality excellent at both 720p and 1080p (tested with an iPhone XR).
If you use Windows and have an iPhone/iPad or an Android device: Use DroidCam. In contrast to Epoccam and iVCam, DroidCam was the only app that actually worked for us (tested with a Windows 10 Surface Book, a MacBook Pro, a Samsung Galaxy Note 7, and an iPhone XR).
The free version of DroidCam for Android provides only 480p video and shows ads. The free version for iOS offers 720p resolution but adds a watermark. For $5, you get 720p video on Android, remove the watermark on iOS, and unlock camera controls.
What sets it apart is that you can pair several Mevo Start cameras together using the Mevo app (iOS, Android) and use them to create a multi-camera setup for conference calls. Each camera also has a mic input so you can use a lavalier mic or small shotgun mic for better audio quality, as well as the ability to accept a microSD card for recording footage directly to the camera.
Footage from the Lumina was unimpressive out of the box, but what really turned us off was the long list of permissions required to use its software. Even after we installed the software and tried to calibrate the Lumina using the included color checker, it still produced footage that was too warm and too soft, especially for a 4K camera. It has other flaws, too, namely a cheap-feeling plastic build and a privacy cap that attaches to the camera with a weak magnet (which we lost just a day after opening the box). Overall, this is not what we expect from a webcam that costs almost $200.
