Capture audio data from a selectable option of sources (e.g., system audio, microphone, or both) using WASAPI (Windows Audio Session API).
Encode audio using the AAC codec.
Take the encoded video and audio streams and multiplex them into a single .mp4 container.
Ensure that audio and video are synchronized by testing the capture using an AV sync test video
UI/UX Considerations, provide appropriate UI controls:
Allow users to select audio sources (system audio, microphone, or both).
Provide feedback mechanisms, like audio meters, to show real-time audio levels.
Give users the option to toggle mute the audio source.
Note: We currently use video-rs a high-level abstraction of ffmpeg-next to encode video, unfortunately there is no audio API implemented, you may need to leverage ffmpeg-next for audio encoding/muxing. You may want to utilize entirely on another crate to encode/mux both video/audio sources, which will require rewriting the existing encode_frames function.
