Whether in games, communications, or media production applications, audio and video content is often a crucial part of modern applications. When working with native APIs, even the simplest audio-visual (AV) applications can be quite complicated, especially when supporting multiple platforms.

- Simple audio playback
- Recording and playing audio
- Recording and playing video
