Video stutters when getting buffer stalled error

[tfernandescunha]

Hello,

We are facing some problems with our videos using the Kaltura Payer on our application, in some vídeos, we are facing some stutters in some particular moments of the video.
We are using the kaltura-player-js embedded in ur page as a script in head:

Kaltura Player lib
kaltura-ovp-player v1.7.1

Expected behavior

Expected any stuttering nor buffer errors/exceptions

Actual behavior

In some videos, we face stutters in some particular moments of the videos that interrupt the video play. Every time that it happens we get a console error "bufferStalledError".

Console output

Hi, our environment is a web application that uses the Kaltura embedded in the head HTML section.
<script src="https://cdnapisec.kaltura.com/p/PARTID/embedPlaykitJs/uiconf_id/CONFID"></script>

The application was developed using vue.js

So I assume that the problem is inside Kaltura Saas.
