Due to the increasing demand and availability of OTT and online content, playback in common Internet browsers has become an essential feature for any web based application. Native video decoding is currently driven by HTML5, but the currently missing support for HEVC/H.265 makes it difficult to process this exciting format for online delivery.

A solution that might help to overcome this problem is WebAssembly, aka WebASM or WASM. The standard allows the creation of web products with video decoding functionality - without the need of relying on 3rd party browser plug-ins which are often rejected by system administrators. Whereas, WASM enables users to develop JavaScript (JS) based, self-contained apps running in Google Chrome, Mozilla Firefox, Microsoft Edge and Apple Safari.

If a workflow in Chrome, Firefox, Edge or Safari requires HEVC/H.265 preview, playback, editing or monitoring, the MainConcept® WebASM HEVC Decoder SDK is the product of choice. The industry-leading MainConcept HEVC Decoder is now available for WASM, so users can develop powerful browser apps featuring H.265 video decoding on every system or mobile device, and in every Internet browser supporting WebAssembly. Due to the nature of the WASM binary format, the MainConcept WebASM HEVC Decoder does not depend on any specific hardware.

The MainConcept WebASM HEVC Decoder offers the same feature set as its powerful cross-platform desktop counterpart supporting many 8-bit, 10-bit and 12-bit profiles up to 4:4:4. The MainConcept WebASM HEVC Decoder SDK also includes a ready-to-use JS sample for quick integration in your app.
