The Zoom Video SDK, designed for developers to build browser-based video applications, has significant feature gaps and performance issues compared to more established developer SDKs like WebRTC. The SDK's proprietary approach to video encoding and decoding using custom WebAssembly modules results in high CPU usage and poor video quality, especially on older devices or variable network conditions. Additionally, the SDK lacks support for standard HTML elements, styling, and positioning of video tiles, as well as features like end-to-end encryption, HLS live streaming, and access to raw media tracks. The Zoom Web SDK's maturity is lower compared to other platforms, and its developer tooling is incomplete, with limited guides and official sample applications that require workarounds for proper functionality on Safari.
