The manifest snip below does not have the layers in order of bitrate. When layer switching events occur are the layers changed according to their order in the manifest or their bitrate?

In other words, does the QualityLevel index value matter or will the client choose the next closest bitrate when a switch event is required and regardless of the index value.

Thanks

Hi,

It’s really down to the player to make the decision.

We know for sure that the bitrate and resolution (width and height) are a factor in the decision, especially WRT to the player size on the embedded page.
