Jul 1, 2025July 2025 monthly summary for the whereby/sdk repository. Key features delivered include enabling P2P VP9 codec handling with a subsequent refactor to remove the explicit p2pVp9On flag and rely on general codec sorting, along with a bandwidth optimization that removes the _KEY SVC encoding option to reduce bandwidth ~15%. These changes improved codec negotiation efficiency, reduced network usage, and simplified maintenance. Impact: improved user experience for P2P calls, lower bandwidth costs, and a cleaner codebase. Technologies/skills demonstrated include VP9 codec handling, feature flag removal, codec sorting, test updates, and overall performance optimization.

Apr 1, 2025April 2025 monthly summary for whereby/sdk: Delivered three primary outcomes across the media and web SDKs: 1) clarified P2P hardware decoding preference by renaming the flag and updating interfaces; 2) improved power efficiency by reordering codec sorting to prioritize hardware-decodable and power-efficient codecs (VP9 placement after AV1/H.264); 3) fixed remote audio playback when the remote participant's video is muted by ensuring audio element rendering/management in VideoMutedIndicator. These changes enhance user experience with more reliable audio/video behavior, reduce device power consumption, and simplify API usage.
