Unreal Engine 5.4 released with Pixel Streaming 2

Unreal Engine 5.4 was officially released on April 23, 2024, with continued improvements to Pixel Streaming for web deployment.

Pixel Streaming 2 (experimental)

• New Pixel Streaming Player component
• Support for H.264, VPX, and AV1 encoders
• Display active pixel streams as media sources within UE projects

Why Pixel Streaming matters

Since Unreal dropped native HTML5 export, Pixel Streaming is the primary way to run high-fidelity UE content in browsers. The game runs on a server and streams video to the browser.

Trade-offs

• Pro: Full Unreal fidelity in browser
• Con: Requires server infrastructure and bandwidth
• Con: Latency-sensitive games may struggle
