PROFILE

Josh Allmann

Joshua Allmann engineered robust real-time streaming and AI-driven video processing pipelines across the livepeer/go-livepeer and livepeer/ai-worker repositories. He architected features such as native WHEP server integration for immediate playback, advanced orchestrator discovery, and resilient live video-to-video transformation, leveraging Go and Python for backend development and concurrency control. His work included optimizing media streaming with FFmpeg, enhancing error handling, and reducing latency through queue management and timestamp correction. By addressing race conditions, improving observability, and modernizing test infrastructure, Joshua delivered maintainable, high-throughput systems that improved reliability, compatibility, and developer experience in distributed, real-time media environments.

October 2025: Stabilized streaming pipeline and accelerated playback startup across Livepeer projects. Key outcomes include: - Bug fix in ai-worker to drop out-of-order frames before muxing to prevent muxer errors when audio inputs are poorly prepared (commit 0a047a2105668d5da4697a3bfa7ff6df2b5dd7cc). - Gateway-native WHEP server introduced in go-livepeer to enable immediate playback connectivity and faster startup, with H.264 video and Opus audio support, timestamp conversion, and improved RingBuffer handling (commit f56f5d5fda542ac611ca46ac75365d6870d35c4f). The WHEP feature is off by default and configurable via LIVE_AI_WHEP_ADDR. These changes deliver tangible business value through reduced latency, higher reliability, and easier operational control.

June 2025: Consolidated growth in live streaming reliability and compatibility for go-livepeer. Delivered end-to-end improvements across iOS RTP timestamp handling, RTMP/Mediamtx ingest, and AI-based live video processing, with a focus on business value (uptime, throughput, compatibility) and maintainable code. Key work includes a TimestampCorrector for iOS RTP at 90kHz, enhanced with platform-specific logic and a kill switch; a MediaMTX output alias with request ID for rapid reconnects and improved logging; reliability hardening of the AI live video module using the orchestrator ManifestID and safer suspension behavior; stabilization of the trickle streaming library to prevent data loss and race conditions; FFmpeg audio re-encoding to AAC for non-local outputs to improve compatibility; and a controlled revert of the iOS timestamp workaround to restore stable handling when required. These efforts reduce drift, improve resilience under adverse network conditions, simplify monitoring, and contribute to a smoother viewing experience.

March 2025 performance summary: Delivered stability and reliability improvements across live streaming, AI processing, and observability. In livepeer/ai-worker, fixed stream teardown delay by relocating the control loop to a critical path, hardened the encoder with a last-value cache, added 48 kHz audio, and streamlined error handling during trickle subscriber close. In livepeer/go-livepeer, launched a WebRTC WHIP ingest server with segment duration enforcement and concurrency fixes, strengthened AI live processing with detached request contexts and standardized logging, and expanded debugging with on-disk input segment logging and unit tests for media I/O. Maintenance work included removing a stale field and enabling HTTP keep-alives/connection reuse to reduce latency. These changes reduce streaming interruptions, lower failure rates, and improve operability and observability, delivering measurable business value in reliability, scalability, and developer productivity.
