Components to use microphone / camera

#### Is your feature request related to a problem? Please describe
With some fantastic new components like text and image annotators enabling seamless data science workflows, it would be cool to take it one step further by using microphones and cameras.

#### Describe the solution you'd like
Components that can capture audio or video using available microphone / camera device from directly inside an app and make the audio / video files available for the app for processing / inferencing.

#### Additional context
This would greatly benefit some of the deep learning apps on audio/video projects, especially Automatic Speech Recognition, Speech-To-Text, Face/Gesture Recognition, Video Inferencing, etc.

The issue names no files, tests, or entry points. Begin by surveying existing components and determine how microphone and camera capture should expose audio and video files for app processing or inferencing; done means the component behavior and supported capture flow are defined and verified.
