I have the same problem with 11.17.
Indeed, by the following set, I was able to play the video in ios.
"uiVars": [
{
"key": "Kaltura.UseAppleAdaptive",
"value": false,
"overrideFlashvar": false
}
]
In this case, it is delivered by [HLS] in ios? Or it is delivered in [HTTP Progressive Download] in ios?
