How to play an LCEVC source with THEOplayer

This article will show you how to play an LCEVC encoded source in THEOplayer. If you are not familiar with THEOplayer, we strongly recommend reading the getting started documentation for web first.

1. Your THEOplayer SDK needs to have the 'lcevc' feature enabled.

You can quickly check using THEOplayer.features. The feature is only available from THEOplayer 4.0 onwards.

2. You need to include V-Nova's Decoder Integration Layer (DIL) on the page.

This example below uses the latest version of the DIL that is maintained by V-Nova:


Setting the source

After your player is correctly configured you can set your LCEVC source, but you need to also include lcevc: true on the SourceDescription so that the player knows how to configure the correct playback pipeline:

DASH example
player.source = {
sources: {
type: "application/dash+xml",
src: "path/to/your/source/master.mpd",
lcevc: true
HLS example
player.source = {
sources: {
type: "application/x-mpegurl",
src: "path/to/your/source/master.m3u8",
lcevc: true


LCEVC enhanced playback only works on modern browsers that support Media Source Extensions (MSE). If the platform does not support MSE (for example: Safari on iOS), the player will fall back to native playback without LCEVC enhancements.
