## Flux: WebM Container Support Added

Flux now supports the WebM container format with Opus codec, providing seamless compatibility with audio sources that output WebM-formatted audio streams.

### WebM Container Support

Flux now accepts WebM containers with Opus codec encoding:

- **WebM containers** with `opus` encoding

When sending WebM containerized audio, **omit** the `encoding` and `sample_rate` parameters—Flux will automatically detect these from the container metadata.

### Why This Matters

WebM is commonly used in web applications and streaming scenarios. This addition makes it easier to integrate Flux with audio sources that natively output WebM format, eliminating the need for format conversion.

### Implementation

**For WebM containerized audio:**
