V-Nova's LCEVC decoder for web
This project is V-Nova's implementation of the LCEVC (MPEG-5 Part 2) decoder for web-based playback. To learn what the LCEVC (Low Complexity Enhancement Video Coding) codec is and how it works, please refer to the V-Nova documentation portal.
Only supported on browsers with Media Source Extensions support.
This project is designed to work alongside any existing web player rather than on its own. Since LCEVC works as an enhancement to existing codecs it works in tandem with decoders for those formats. Within web environments, the native system decoders are typically used to decode the base video codec as an input to LCEVCdecJS to provide the LCEVC enhancement decode and rendering.
Simple LCEVC-enhanced player implementations may also be accomplished by directly using Media Source Extensions.
LCEVC decoding support is included within the Shaka Player project from version 4.3 onwards. Therefore, if you are building Shaka Player, LCEVC support can be easily enabled by including this project and using player.configure('lcevc.enabled', true);. Please visit the Shaka Player project for more details.
Install the dependencies using npm install and build the library with npm run build. Run
the tests with npm run test to confirm that LCEVCdecJS is built succesfully. More
detailed guides are available for various environments:
