How to know which sessions support pause, unpause etc?

[Inrego 76]

Hello. I'm building some sort of remote control of current sessions to Home Assistant, but how do I know which sessions support pausing? From my tests, I can send a pause command when playing on my Android TV device, but if I send it to a Web Client, I get an error from the server.

Hi, thanks I'll test that issue out. You can check out the remote control wiki here:

 

https://github.com/MediaBrowser/Emby/wiki/Remote-control

 

the api will tell you what the supported commands are for a given session.

Hello. Thank you for your response. I meant playstates, not commands.

I did see that there is SupportedCommands response on the webservice, but none of them show the pause since it's a playstate, not a command. Here's a link to the relevant part that I mean:

 

https://github.com/MediaBrowser/Emby/wiki/Remote-control#sending-a-playstate-command

 

Sending these doesn't work for WebClients as far as I've experienced. Is that a bug? Or is there a way to check if a session supports settings these playstates.

the playstate commands will also be in the list of supported commands. yes there is ongoing work involved with controlling another instance of the web client so there might be some issues there. theater is fully controllable though.

I'm not sure I understand. Let me elaborate.

 

When I call GET on /Sessions, I get the following for my Android TV:

[
  {
    "SupportedCommands": [
      "DisplayContent",
      "Mute",
      "Unmute",
      "ToggleMute"

      "IsPaused": false,
      "IsMuted": false,

    }
  },
  {
    "SupportedCommands": [
      "GoHome",
      "GoToSettings",
      "VolumeUp",
      "VolumeDown",
      "Mute",
      "Unmute",
      "ToggleMute",
      "SetVolume",
      "SetAudioStreamIndex",
      "SetSubtitleStreamIndex",
      "DisplayContent",
      "GoToSearch",
      "DisplayMessage",

    ],
    "QueueableMediaTypes": [

    ],

    }
  }
]

Pause and Unpause are not listed here under "SupportedCommands". However, calling the webservice /Sessions/{Id}/Playing/pause does in fact pause the current video on that device, and unpause resumes the video. From my understanding the commands listed in "SupportedCommands" are only for the /Sessions/{Id}/Command/{CommandName} webservice, and unrelated to the playstate commands.

Sorry, maybe i was wrong. My memory was a little fuzzy on that. The supported commands list came after the playstate commands so in order to retain compatibility that's they are just assumed supported if SupportsRemoteControl is true.

No worries It's quite a large api endpoint to know by memory. And it does also seem like web clients return false on the SupportsRemoteControl property, so that's all I needed, thanks! (How did I not see that property myself?)
