This guide explains the possible origins of any potential latency you might experience between the source of a video and its live broadcast via the Infomaniak Video Streaming service.

Availability in the case of...

...rendering on the Manager

Once your encoder is connected to the Infomaniak master-type servers, the stream may undergo several transformations, particularly in the case of transcoding or the addition of a logo as a watermark. In these scenarios, the video must be re-encoded in one or more formats, which requires processing time that inevitably affects the final rendering.

...single bitrate stream without reprocessing

In this case, the stream is available after just a few seconds.

...transcoded stream or with watermark

This processing takes approximately 25 seconds for the transformed stream to be visible in the different qualities.

...lag between the source and the rendering for viewers

To avoid micro-cuttings during the broadcast, the player (video player) buffers several seconds of the video. You can thus easily notice a 30 to 60 second lag between the original source and the stream rendered for viewers.

To minimize this lag, the only way is to have a single bitrate stream, without transcoding, without watermark, with a bitrate not too high, and to reduce the buffer as much as possible in the player configuration. Depending on your needs, it is therefore necessary to make a compromise between the instantaneity of the broadcast and the features you want to use to enhance the experience of your viewers and personalize the branding of your live streams.
