Video Effects SDK 3.13.1 for Web

This release updates the default segmentation models and improves SDK startup across WebGPU and self-hosted WASM configurations.

Updated#

• Quality and balanced segmentation models. The default landscape and portrait models for the quality and balanced presets have been updated to versions 1.6.0 and 5.6.0 respectively.
• ONNX Runtime Web build. The bundled ONNX Runtime package has been refreshed.

Fixed#

• WebGPU compatibility fallback. When a browser exposes WebGPU but cannot provide the adapter information required by ONNX Runtime, the SDK now falls back to CPU WASM instead of failing during session creation. The CPU_FALLBACK notice includes the compatibility reason and failure stage.
• WebGPU device parameters. Adapter information is normalized on the GPU device before it is passed to ONNX Runtime, fixing session initialization on affected browser and runtime combinations.
• WASM runtime resolution with both a script URL and sdk_url. The SDK checks the script directory first and falls back to sdk_url when the runtime is not served there. Explicit wasmPaths configuration still takes precedence and prevents fallback to a third-party origin.
• Duplicate WASM runtime lookups. Runtime path resolution is cached for the active configuration, avoiding repeated probes and duplicate warnings during initialization.

Added#

• WASM_RUNTIME_LOCATION_FALLBACK (1068). Reported when the runtime is not available at the first candidate location and the SDK uses the next configured location. data contains { resolved, skipped }.

Upgrading#

No configuration changes are required when upgrading from 3.12.1.

If you self-host SDK assets, continue to place ort-wasm-simd-threaded.asyncify.wasm next to the SDK bundle or configure its exact location explicitly:

sdk.config({
  wasmPaths: {
    wasm: 'https://your-domain.com/assets/ort-wasm-simd-threaded.asyncify.wasm'
  }
});
