call.adv.stats_ms is a numeric property controlling Chrome remote media statistics.
call.adv.stats_ms only works in Chrome browser. On other browsers no statistics is available, nothing happens when you set call.adv.stats_ms.
Numeric:
Avoid values lower than 500 (0,5 seconds) to avoid excessive CPU strain.
0
Set call.adv.stats_ms to more than 100 (preferably 500) to make event function wrtc.onStats() be repetitively called while in call with someone. You may change call.adv.stats_ms at any time.
Set call.adv.stats_ms=0 to turn statistics off again.
On non-Chrome browsers, or when not in call, no event wrtc.onStats() will occur.
If wrtc.adv.volumeMeter() has been called call.adv.stats_ms also determine how often wrtc.onVolume() events will occur.
