KODI JSONRPC Player.GetItem method provide empty details - json-rpc

Question

I start a new video with JSON-RPC call:
{"jsonrpc": "2.0",
"method": "Player.Open",
"params":
{"item":
{"file": "c:\\MyCodes\\samples\\sample-6s.mp4" }},
"id": 1
}
Video started and I want to get the video details and use the following Player.GetItem method:
{
"jsonrpc": "2.0",
"method": "Player.GetItem",
"params": {
"properties": [
"title",
"album",
"artist",
"season",
"episode",
"duration",
"showtitle",
"tvshowid",
"thumbnail",
"file",
"fanart",
"streamdetails"
],
"playerid": 1
},
"id": "VideoGetItem"
}
The problem I got back this:
{
"id": "VideoGetItem",
"jsonrpc": "2.0",
"result": {
"item": {
"album": "",
"artist": [],
"episode": -1,
"fanart": "",
"file": "c:\\MyCodes\\samples\\sample-6s.mp4",
"label": "sample-6s.mp4",
"season": -1,
"showtitle": "",
"streamdetails": {
"audio": [],
"subtitle": [],
"video": []
},
"thumbnail": "",
"title": "",
"tvshowid": -1,
"type": "unknown"
}
}
}
but if I start the same video from KODI GUI I got back this:
{
"id": "VideoGetItem",
"jsonrpc": "2.0",
"result": {
"item": {
"album": "",
"artist": [],
"episode": -1,
"fanart": "",
"file": "C:\\MyCodes\\samples\\sample-6s.mp4",
"label": "sample-6s.mp4",
"season": -1,
"showtitle": "",
"streamdetails": {
"audio": [
{
"channels": 2,
"codec": "mp3",
"language": ""
}
],
"subtitle": [],
"video": [
{
"aspect": 1.3333330154418946,
"codec": "mpeg4",
"duration": 2701,
"hdrtype": "",
"height": 384,
"language": "",
"stereomode": "",
"width": 512
}
]
},
"thumbnail": "image://video#C%3a%5cMyCodes%5csamples%5csample-6s.mp4/",
"title": "",
"tvshowid": -1,
"type": "unknown"
}
}
}
Any idea, or experience? Maybe I should use a different method to get the currently running video details?
