Mission critical delivery of reliable high-quality video with minimal bandwidth impact.

Internet browser support is a must have feature for any web-based application looking to engage more viewers. HEVC/H.265 is a top codec of choice for high quality video viewing, but HTML5 doesn’t support it, which degrades the user experience.

WebAssembly, aka WebASM or Wasm, is a simple option to securely view videos on any web browser, anywhere, using the latest and greatest codec technology, without needing 3rd party browser plug-ins. WebAssembly lets you develop secure JavaScript (JS) self-contained apps that run in Google Chrome, Mozilla Firefox, Microsoft Edge and Apple Safari.

MainConcept WebASM HEVC Decoder SDK is an ideal solution for browser-based workflows that require HEVC/H.265 preview, playback, editing or monitoring. With the MainConcept HEVC Decoder, you can build powerful applications with optimized performance for multi-threaded H.265 video decoding on any device with an Internet browser supporting WebAssembly. And, since WebAssembly is a binary format, the MainConcept WebASM HEVC Decoder does not require specialized hardware or software.

Our WebASM HEVC decoder offers the same feature set as its powerful cross-platform counterpart, supporting 8-bit, 10-bit and 12-bit profiles up to 4:4:4. It comes with a simple tool for testing performance and conformance using different processing modes, and includes JavaScript samples for quick application integration.
