JWPlayer failing on polyfills.vttrenderer.js
I am using JWPlayer to stream videos with VTT captions. It is working fine in all the current browsers but failing sometimes on Safari 9 and IE 11 and below with the following error which is hampering other operations which are based on the on('time') event.
Error: NotSupportedError: DOM Exception 9: The implementation did not support the requested type of object or operation. createProcessingIntruction -- polyfills.vttrenderer.js:1:2067
Anyone else facing similar issues? Any suggestions?
