Chrome 107 Enables HEVC Hardware Decoding: Impact and Contributions from ByteDance Engineer
Chrome 107 Enables HEVC Hardware Decoding: Impact and Contributions from ByteDance Engineer, enabling lower deployment costs, better user experience for high‑resolution video, and detailing the developer’s journey, challenges, and future plans across platforms.
Chrome 107 rolled out HEVC hardware decoding support to all users on October 25, 2022, following an official note on October 21.
The advancement was driven by ByteDance open‑source contributor Zhū Sīdá, whose work enabled hardware‑accelerated HEVC playback in Chromium.
HEVC offers roughly half the bitrate of H.264 for comparable quality, reducing CDN traffic and transcoding costs, especially for 4K/8K and HDR video.
With Chrome’s 67% market share, sites can now deploy HEVC video efficiently, lowering deployment costs and improving user experience on older devices.
The article details the contributor’s background, the challenges faced (patent concerns, sandbox limitations, GPU driver edge cases), and the development process across macOS, Windows, and Android platforms.
Future work includes HEVC with Alpha performance improvements, zero‑copy HDR tone mapping, and WebCodec encoding support.
