Latency Control Modes

Click PLAY button to start

Introduced in nanoStream H5Live Player Version 4.14.x, two new latency control modes have been added, targeting especially lowest latency use cases like live auctioning. The latency control mode can be selected via the added playback.latencyControlMode configuration parameter. The established latency control mode is available as the classic option which remains to be the default mode. In addition the new latency control modes balancedadaptive and fastadaptive have been added. According to the current stream and network conditions they can adjust the latency adaptively. This allows to achieve a lower latency while keeping the playback experience smooth.

Supported platforms and browsers

This feature is particularly helpful in i.e. live auctioning, where even lower latency is crucial. The usage depends on the needs, however, in most cases the "classic" mode is enough to achieve a satisfying viewing experience.

v.4.14.1

Version 4.14.x added support for all major desktop and Android browsers.

Desktop Windows/Mac/Linux: Chrome, Edge Chromium (80+), Firefox, Safari, Chromium-based browsers
Android: Chrome, Firefox, Chromium-based browsers
iOS is planned to follow soon

For unsupported platforms/browsers the player is doing automatic fallback to "classic" mode.

Configuration

Accessing latency control modes is possible via playback.latencyControlMode in the player configuration.

Parameter name: config.playback.latencyControlMode

var config = {
    "playback": {
        ...
        "latencyControlMode" : "balancedadaptive",
        ...

var config = {
    "playback": {
        ...
