One of the features I was expecting to see in Android 14 was the ability to turn your phone into a USB webcam for your PC.
Google hasn't talked about this feature yet, but I hope they still plan to ship it!
Here's some tidbits about Android 14's USB webcam feature 👇
So back in February, I discovered (https://twitter.com/MishaalRahman/status/1621194700790054914) code changes in AOSP that hinted at a new "DeviceAsWebcam" service (which upon re-reading the code changes I now believe to be a separate system app) that "turns an Android device into a webcam."
Android devices that support the UVC gadget mode (ie. the kernel is compiled with CONFIG_USB_CONFIGFS_F_UVC=y) can be set up to send camera frames to a /dev/video* node that a host device supporting UVC webcams can read from.
