Remote Play Item not working ... ?

[rbjtech 5284]

This used to work (as we used it for the early Introskip testing..) but I can no longer appear to remote play an item using the session service.

All works fine for remote browse to an item, remote send a message,  remote play/pause an item (so session control is there..) - but I just can't 'start/play' an item - it just says Playback Error on the client (Emby Theater for Windows in this case)

Trying to use via the swagger api for the moment -

curl -X 'POST' \
  'http://embyserver:8096/emby/Sessions/a178ecd0c8aa2feb006397adb79092d8/Playing?ItemIds=4191016&StartPositionTicks=0&PlayCommand=PlayNow&api_key=bdda47723d224c36b31f5abda7a****' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json' \
  -d '{
  "ControllingUserId": "string",
  "SubtitleStreamIndex": 0,
  "AudioStreamIndex": 0,
  "MediaSourceId": "string",
  "StartIndex": 0
}'

Debug log output for that API command

Any thoughts/clues ?

Thanks !

Ah - so tried a different client - AndroidTV on the same network as the server (vlan 30) - and for that session it works ok ..

So it's either Emby Theater itself or the fact that client is on a different network to the server - but then why do all the other API functions work ok .. ?

Going to do some more digging ...

Using the web app to remote play to Theater works just fine in my testing, so what I would suggest is opening the chrome debugger and then comparing the request that the web app sends to what you're saying. That should lead you to the answer.
