AI Summary

This release focuses on enhancing media codec support (specifically H.264 profiles), improving testing coverage with mocks and downstream packet tests, and adding detailed Prometheus metrics for latency and status codes. It also includes several bug fixes regarding packet handling and timestamp calculations.

Key Highlights

Added support for more H.264 profiles
Enhanced testing capabilities with mocks for region pins and downstream packet push
Improved observability with new Prometheus metrics for latency and stream start times
Optimized VP9 handling using the simulcast constructor
Fixed a potential panic in reference layer RTCP timestamp handling

New Features

Mock for testing region pins with API
Country field added to participant closing log
Support for more H264 profiles
Status code for Twirp request latency Prometheus metric
Logging for high stream start latency
