How to live stream video from camera using the new createCaptureSession API in Android App? - API 34
In this video it shows the steps to create live streaming video from the phone's camera on the Texture View widget of your Android App.
It uses the new CameraDevice.createCaptureSession(sessionConfiguration) API. The previous versions of this API are deprecated from API version 30 onwards.
