Updates to Dolby OptiView's Real-time Streaming Platform and Media Server.

## 2026-07-16

### Media Server

<!-- 3.4.3 -->

#### Fixes

- Improved RTMP re-stream reliability by handling output back-pressure to prevent stream corruption.
- Fixed audio distortion that could occur with loud audio sources during WebRTC playback.
- Fixed an issue where recordings of simulcast WebRTC streams could be missing video.
- Improved Adaptive Bitrate (ABR) resilience on links with high RTT variation, preventing unnecessary switches to lower-quality layers.
- Fixed an issue where abnormal viewer disconnections could prevent new viewers in a region from receiving media.
