Unable to get playback status when using integrated player in Jellyfin android

[tatamiboy]

Describe the issue
When using the integrated player in Jellyfin android I can't get the playback status and no scripts are loaded.
When I sent a request to the jellyfin api using the curl command
curl [ServerIp]/Sessions -H "Authorization: MediaBrowser Token=[ApiKey]" | jq | grep Id,
the response contained two DeviceIds, and the order was different between the web player and the integrated player.

When making a request in the format [ServerIp]/Sessions?ApiKey=[key]&DeviceId=[id], it seems necessary to specify the first DeviceId.

For the web player:

"Id": "****",
"UserId": "****",
  "ServerId": "****",
  "Id": "****",
  "ChannelId": null,
  "ProviderIds": {},
  "ParentId": "****",
"DeviceId": "28c0b44b74216c7c",
    "Id": "****",
    "PlaylistItemId": "playlistItem1"
    "ServerId": "****",
    "Id": "****",
        "Id": "****",
    "ChannelId": null,
    "ProviderIds": {},
    "ParentId": "****",
    "DisplayPreferencesId": "****",
"PlaylistItemId": "playlistItem1",
"ServerId": "****",
  "SupportsPersistentIdentifier": true,
"Id": "****",
"UserId": "****",
"DeviceId": "28c0b44b74216c7c1306d0f125d84c849df7c75aa97deafb",
"ServerId": "****",

[ServerIp]/Sessions?ApiKey=[key]&DeviceId=28c0b44b74216c7c→ Playback status can be obtained.
[ServerIp]/Sessions?ApiKey=[key]&DeviceId=28c0b44b74216c7c1306d0f125d84c849df7c75aa97deafb → Unable to obtain playback status

For the integrated player:

"Id": "****",
"UserId": "****",
  "ServerId": "****",
  "Id": "****",
  "ChannelId": null,
  "ProviderIds": {},
  "ParentId": "****",
"DeviceId": "28c0b44b74216c7c1306d0f125d84c849df7c75aa97deafb",
"ServerId": "****",
  "SupportsPersistentIdentifier": false,
"Id": "****",
"UserId": "****",
"DeviceId": "28c0b44b74216c7c",
    "Id": "****",
    "PlaylistItemId": "playlistItem1"
    "ServerId": "****",
    "Id": "****",
        "Id": "****",
    "ChannelId": null,
    "ProviderIds": {},
    "ParentId": "****",
    "DisplayPreferencesId": "****",
"PlaylistItemId": "playlistItem1",
"ServerId": "****",

[ServerIp]/Sessions?ApiKey=[key]&DeviceId=28c0b44b74216c7c1306d0f125d84c849df7c75aa97deafb→ Playback status can be obtained.
[ServerIp]/Sessions?ApiKey=[key]&DeviceId=28c0b44b74216c7c → Unable to obtain playback status

---

Expected behavior
Get the correct device ID and get the playback status in the integrated player.

I don't know how to read your output, can you post full json response when calling /Devices and /Sessions?

[tatamiboy]

The output of the first post is the response of
curl [ServerIp]/Sessions -H "Authorization: MediaBrowser Token=[ApiKey]" | jq | grep Id.
Only the parts related to Id are extracted using grep. Due to my lack of understanding, I posted a confusing and incorrect explanation. I'm sorry.

The full json response is as follows (The device in issue is the A202ZT) :
/Sessions (Playing in integrated player):

The web player and the integrated player are in separate sessions, and the integrated player's DeviceId is in the form of [Id, which can be obtained from /Devices] + some string.

[Yoooi0]

What is the difference between integrated and web players?

Having two sessions on one device does not make sense so I dont know how to handle this.

DeviceId is in the form of [Id, which can be obtained from /Devices] + some string

Its Id + LastUserId

[tatamiboy]

What is the difference between integrated and web players?

This is the player that can be selected from the Jellyfin Android client settings. The app description says the following:

Web player:
The default HTML video player from the Web UI.

Integrated player:
Based on ExoPlayer, supports more video formats and codecs, and is more integrated into the OS.

I would like to use the integrated player because it has more features and supports more codecs.

[Yoooi0]

For now my only idea is to rewrite the whole Jellyfin source to enable users to select sessions instead of devices.
This probably warrants a question on jellyfin forums/github how this is supposed to be handled.
If you can filter sessions by DeviceId but there is a session with DeviceId not present in /Devices, then imo its a bug.

[tatamiboy]

I see, so it is not a problem that should be handled on the MFP. I understand.
Thank you for your response.
