NanoPlayer - Release Overview

[4.12.0]

Release Notes

This version is adding the option to configure the minimum number steps during an ABR initialized switch down via the adaption.downStep parameter. Potential related use case are configurations containing a higher number of qualities or configurations with rather close rendition bitrates. The detection of the available buffer time has been improved for iOS in general and iOS 15 in particular. A timing related condition that could lead to buffering after a stream switch has been fixed. The start-buffer calculation in bufferDynamic mode has been fixed to prevent out of range values. Assigning null values to non mandatory configuration parameters will no longer lead to a setup error.

Changelog

Added

new option config.source.options.adaption.downStep
- for ABR automatic 'deviationOfMean' and 'deviationOfMean2' only
- allows to define the minimum number of steps during a ABR initialized down switch via the adaption object
- if the number of remaining lower renditions is smaller than the value then the switch will be performed to the lowest rendition
- default value is 1
- e.g.:
```
"adaption": {
    "rule": "deviationOfMean2",
    "downStep": 2
}
```

Improved

detection of the available buffer time for iOS in general and iOS 15 in particular
config warning message in case of wrong configured properties of an entry

Fixed

timing related condition that could lead to buffering after a stream switch
start-buffer calculation in cooldown if bufferDynamic is enabled
- prevent lower values than the original configured start buffer value
assigning null values to non mandatory configuration parameters will no longer lead to a setup error
