The webcam capture feature will not be available on YouTube after 16 January 2016.
Previously, if you had a webcam built in or connected to your computer, you could record a webcam video on YouTube and upload it directly to the site. This feature will be turned off because it is rarely used and is built on technology that is no longer supported.
Alternatives to webcam capture
You can use software on your computer to record and save a webcam video, and then upload the video to YouTube. Popular software includes Photo Booth for Mac OS X and Camera for Windows 8+. If you have another OS, you may need to look up how to record videos using your webcam by referencing your device manual or searching online.
